I’m excited for this event which a handful of us at Microsoft helped organize, planned and produced this amazing technical event for IT pros. Looking forward to seeing you at Microsoft Technical event, for you learning, and engagements.

Harjit Joins Microsoft!

The time has come to let the ?‍? out of the bag and make the formal announcement. On May 21, 2021, I wrote a blog post where I mentioned that I left my 18 year career in Higher-Ed as a Senior Systems Administrator at the University of Vermont.

I am excited to announce that as of today, June 7, 2021, I have joined Microsoft as a Customer Engineer for Microsoft 365. My role covers a variety of solutions under the Microsoft 365 umbrella including Modern Management which I’m very passionate and super excited about. I can finally say that I’m now a “Blue Badge” and my dream of joining Microsoft has come true!

There is so much that I want to mention and perhaps, I’ll start with my family. My wife Jenny and my daughters Sabrina and Hannah have been my rock, strength, motivation, strong supporters for what I do, and they highly encouraged me to pursue my dreams and passion. Thank you!

I’ve been privileged and honored to be a Microsoft MVP since January 2017, and I have grown and learned so much since then, as well as had many amazing opportunities, from guest blogging, consulting work, product reviews, NDA opportunities with Microsoft, Subject Matter Expert (SME) on various webinars and technical user groups, speaking engagements with several conferences including Microsoft Ignite in Orlando, Microsoft Ignite The Tours in Milan, Johannesburg, and Dubai (unfortunately COVID-19 cancelled my speaking gigs in Zurich, Mumbai, Bangalore, Tel-Aviv, and Chicago), TechMentor, IT/Dev Connections, and the one close to my heart and my favorite MMS aka MMSMOA, to name a few. During this journey, I developed strong bonds, positive reputation, respect, and trust among Microsoft product groups, MVP Program leadership, fellow Microsoft MVPs, vendors, event organizers, IT Professional community, mentees, my wonderful followers, and close friends. Thank you to all of you for your support, guidance, encouragement, and friendships.

Today also marks the end of the road for my Microsoft MVP award, which is something one has to give up upon joining Microsoft as an employee. I will continue to be a valuable resource not only to the MVP Program, the leadership, but to the IT Pro community as well, and will continue to empower everyone and help improve what I can. Thank you Betsy Weber, Rochelle Sonnenberg, and Christian Talavera for allowing me to do what I do, and most importantly for all the amazing opportunities as well as for my inclusivity as one of the trusted leaders within the MVP program. Also, Thank you Cathy Moya for the same and so much more. It’s amazing that we are all colleagues now. ??‍???

There are a few people who I would like to mention and recognize, who have been instrumental for my next career phase with Microsoft. The offline chats, references, internal recommendations, referring to open positions, keeping me in check, pushing me harder, motivations, encouraging me to stay positive, mentorship, discreet conversations, trust, friendships, and so much more, meant a lot to me and I’m forever appreciative and grateful. I know I am going to miss mentioning someone or another, and for that I apologize in advance and please forgive me. In no particular order, Thank you very much Noel Fairclough, Rod Trent, John Deardurff, Art Hogarth, Cathy Moya, Heather Poulsen, Kerim Hanif, Kris Loranger, Joe Lurie, and last but not least Julie Andreacola.

Thank you to Prayer Solanky who I consider my brother, and has been there for me in good times, during challenging moments of my life, provides tons of valuable advice, keeps me grounded and humble always, and who I trusted with my journey to Microsoft.
Also, Thank you to my wonderful friends Mick Pletcher, Anoop Nair, Richard Hay, John Yoakum, Jen Sheerin, Ben Dumke, Mary Jo Foley, Scott Ladewig, Ben Whitmore, James Petty, Jitesh Kumar, Octavio Rodriguez, Damien Van Robaeys, Nick Pilon, Benoit Lecours, Brian Mason, Greg Ramsey, Mirko Colemberg, Johan Arwidmark, Anne Baker, Peter De Tender, Adnan Hendricks, Team MMS, The Krewe, Team Devops Collective, Team SCDudes, and so many more. Last but not least, my close “Ignitable” friends (Pat, Dean, Brandon, Kenji, Stu, Henrik, Stuart, Joe, Travis, and Jin.

As I celebrate this happy occasion, I’m also reminded of my brother Amarjit who passed away on this very day (June 7th) in 2015. I miss him very much, but I know he is proud of me and is watching over me from heaven. ???

With all that said, it’s time to kick start my new adventures with the company and people I love, embrace the unique opportunities, advocate and evangelize modern technologies, support the IT Pro community, and I’m ready to “empower every person and every organization to achieve more”! ?‍??‍??‍??‍???✔

Vulnerability details for the current month

Below are summaries for some of the security vulnerabilities in this release. These specific vulnerabilities were selected from the larger set of vulnerabilities in the release for one or more of the following reasons: 1) We received inquiries regarding the vulnerability; 2) the vulnerability may have received attention in the trade press; or 3) the vulnerability is potentially more impactful than others in the release. Because we do not provide summaries for every vulnerability in the release, you should review the content in the Security Update Guide for information not provided in these summaries.

Notes on details in the vulnerability summaries:

Attack VectorThis metric reflects the context by which vulnerability exploitation is possible. The Base Score increases the more remote (logically, and physically) an attacker can be in order to exploit the vulnerable component.
Attack ComplexityThis metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability. Such conditions may require the collection of more information about the target or computational exceptions. The assessment of this metric excludes any requirements for user interaction in order to exploit the vulnerability. If a specific configuration is required for an attack to succeed, the Base metrics should be scored assuming the vulnerable component is in that configuration.
Privileges RequiredThis metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.
User InteractionThis metric captures the requirement for a user, other than the attacker, to participate in the successful compromise the vulnerable component. This metric determines whether the vulnerability can be exploited solely at the will of the attacker, or whether a separate user (or user-initiated process) must participate in some manner.

Vulnerability details for the current month:

Below are summaries for some of the security vulnerabilities in this release:

Attack VectorThis metric reflects the context by which vulnerability exploitation is possible. The Base Score increases the more remote (logically, and physically) an attacker can be in order to exploit the vulnerable component.
Attack ComplexityThis metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability. Such conditions may require the collection of more information about the target or computational exceptions. The assessment of this metric excludes any requirements for user interaction in order to exploit the vulnerability. If a specific configuration is required for an attack to succeed, the Base metrics should be scored assuming the vulnerable component is in that configuration.
Privileges RequiredThis metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.
User InteractionThis metric captures the requirement for a user, other than the attacker, to participate in the successful compromise the vulnerable component. This metric determines whether the vulnerability can be exploited solely at the will of the attacker, or whether a separate user (or user-initiated process) must participate in some manner.

February 2021 Microsoft Office security updates

Microsoft Office security updates are delivered through the Microsoft Update platform and via the Download Center.

Patched Office security vulnerabilities – (Source: Bleeping Computer)

This month’s Office security updates address bugs exposing Windows systems running vulnerable Click to Run and Microsoft Installer (.msi) based editions of Microsoft Office products to remote code execution (RCE), information disclosure, and spoofing attacks.

Microsoft rated the six RCE bugs patched in February 2021 as Important severity issues given that they could enable attackers to execute arbitrary code in the context of the currently logged-in user.

Following successful exploitation, attackers could install malicious programs, view, change, and delete data, as well as make their own admin accounts on exploited Windows devices.

How to Use and Configure Outlook Shared Mailbox

Generally, admins setup a shared mailbox to improve collaboration between teammates and simplify email organization. This blog post explains how to use and configure Outlook shared mailbox with step-by-step instructions, as well as what to do when you face issues with the shared mailbox.

Outlook shared mailbox is a mailbox that can be accessed by multiple users in an organization. It allows teammates to coordinate and manage activities, and all the members can read and send emails from the mailbox, update shared calendars, etc.

The following are a few benefits of using Outlook shared mailboxes:

  • Multiple employees in an organization can share the responsibility of handling and replying to the emails of a single mailbox.
  • Outlook calendar and contacts information can be shared between multiple employees.
  • Admin can assign specific permissions to the members of shared mailbox for security and transparency.

How to Use Outlook Shared Mailboxes?

A shared mailbox automatically shows up in your Outlook profile once the Exchange admin adds you as a member of the mailbox. If you don’t see the shared mailbox, you can restart Outlook and check again.

Note: It may take a while for the shared mailbox to display in your Outlook profile.

If you don’t see the shared mailbox in your Outlook profile even after restarting Outlook, you can add it manually by following these steps:

  • Launch Outlook and go to File > Account Settings > Account Settings.
  • Open the Email tab, select your account, and then click Change.
  • Select More Settings > Advanced > Add.
  • Enter the email ID of the shared mailbox and click OK > OK.
  • Click Next > Finish and then close the window.

How to Send an Email from the Shared Mailbox?

Once you have successfully setup a shared mailbox, you can send emails by following these steps:

  • Launch Outlook and click New Email.
  • Click the From field at the top and select the shared mailbox email address. If you don’t see the shared email address, select Other email address and manually enter the email address. Then click OK.
  • Enter your message and click Send. Now, whenever you will create a new message, you will see the shared email address in the drop-down list in the From field.

How to Use Shared Calendar and Contacts?

Once admin has allowed you to use Outlook Shared Mailboxes, the shared calendar and contacts are automatically added to the appropriate lists in your Outlook profile.

To use calendar associated with the shared mailbox:

  • Go to Outlook and open the calendar view.
  • Then select the shared mailbox.

You need to know the following things about shared calendars:

  • When you create appointments in a shared calendar, whoever has access to the shared mailbox can see these appointments.
  • Members of shared mailbox can create, view, and edit appointments in the calendar.

Like in the case of shared calendar, the shared contacts are added to your My Contacts list automatically, once the admin allows you to use Outlook shared mailboxes. To access the shared contacts, follow these steps:

  • Launch Outlook and select People.
  • Under My Contacts, select the shared contacts folder.

How to Use Shared Mailbox in Outlook Web Access (OWA)?

If you want to open a shared mailbox in a web browser via OWA, you need to know how to setup a shared mailbox in your account manually. Following are the steps to setup a shared mailbox:

  • Sign in to your OWA account. If you are using Office 365, sign in to your account and launch Outlook.
  • Right-click on a folder or your mailbox in the navigation pane, and click Add shared folder
  • Enter the email ID of your shared mailbox in the dialog box and click Add.

Troubleshooting Shared Mailbox Issues

Outlook stores shared mailboxes data, like other mailbox items, locally in Outlook data file (OST). Sometimes, this OST file gets damaged or becomes inaccessible due to various reasons that include network connection issues, storage device failure, virus infection, etc. The problems with OST file may make your shared folder inaccessible or lead to syncing issues with the shared folder.

In such cases, you can delete and recreate the OST file to resolve the issues. However, if you’re not able to recreate the OST file or there are locally saved items in the file, you can recover the OST file data and save it in Outlook importable PST file by using a specialized OST to PST converter software such as Stellar Converter for OST. The software can easily convert an inaccessible or orphaned OST file into PST, in a few clicks.

Conclusion

Shared mailboxes in Outlook make it easy for small teams to manage and send emails from a common email address. These mailboxes also allow you to share contacts and calendars with the members. It’s easy to use and configure Outlook shared mailbox. You can access the shared mailbox almost instantly after the admin has made you a member.

Sometimes, you face some issues with your shared mailbox. This may usually happened due to problems with the OST file. In such a case, you can recreate the OST file to resolve the issue. If this doesn’t work, you can use an OST converter tool such as Stellar Converter for OST to save your OST file data in Outlook importable PST file.

Microsoft MVP Renewal 2020-2021

I’m so Thankful, honored, and excited to receive the confirmation email (below) from the Microsoft Most Valuable Professional (MVP) Award team confirming my award renewal for the 2020-2021 year. This is my fourth consecutive award since receiving my first one on January 1, 2017. It has been a wonderful, exciting, fun, challenging, and rewarding experience with so many positive opportunities.

The MVP award has provided me with some great opportunities in terms of my career growth, skill development, and various avenues to give back and help others in the IT Professional community. I had been invited to speak and delivered technical and soft skill sessions at conferences such as Microsoft Ignite Orlando 2019, Midwest Management Summit (MMSMOA), MMS Jazz Edition (New Orleans), and most recently covered the international circuit at Microsoft Ignite The Tour in Milan (Italy), Johannesburg (South Africa), and Dubai (UAE). I was also scheduled to deliver sessions on behalf of Microsoft at Microsoft Ignite The Tour in Zurich (Switzerland), Mumbai (India), Bangalore (India), and Tel Aviv (Israel), however these events were unfortunately cancelled due to COVID-19. I have also delivered various webinars, guest and ghost blogged, joined some technical expert panelist, reviewed technical books, tested and evaluated software, provided technical expertise, guest on podcasts, moderated technical forums, and engaged with the community both in person and online.

This is my 4th MVP Award and I am very grateful and appreciative for this honor and for the various opportunities provided to me over time. Thank you very much to each and every one of you for making me successful in my efforts as a MVP, IT Professional, and community contributor, and for providing me with the valuable resources and networking opportunities. I could not have achieved any of the above without the support and encouragement from the community, my friends in the technology industry, people I look up to as mentors, my mentees who keep me on my toes, wonderful Program Managers at Microsoft, a few industry leaders, and last but not least my loving family. Thank you!

I would like recognize and give my special Thank you to:

How To Install ConfigMgr Client On VDI Template

The installation of the ConfigMgr client on workstations and servers is pretty straight forward, and can be done manually, with Client Push, and Software Update Based client installation to name a few. However, it is not as simple when dealing with Windows VDI systems, where extra steps need to be taken to avoid duplicate ConfigMgr client GUIDs and certificates on cloned VDI systems. Below are the steps to follow.

On the master or template system:

  1. Install the ConfigMgr client. Ensure it is properly functioning and has all the necessary components and actions.
  2. Stop the SMS Host Service. This can be done by launching the Command Prompt (CMD) as Administrator and running the following command:
    net stop ccmexec
  3. Delete the SMSCFG.ini file from the Windows folder location. In Administrator CMD, run the following command:
    del %WINDIR%\SMSCFG.ini
  4. Delete the SMS Certificates. To do this, launch PowerShell as Administrator and run the following command:
    Remove-Item -Path HKLM:\Software\Microsoft\SystemCertificates\SMS\Certificates\* -Force
  5. Remove the Inventory Action ID 1 in WMI. You can run the following command:
    wmic /namespace:\root\ccm\invagt path inventoryActionStatus where InventoryActionID=”{00000000-0000-0000-0000-000000000001}” DELETE /NOINTERACTIVE
  6. Once the above steps have been completed, shutdown the master template, capture a snapshot, and provision the VDI systems. At this point, each VDI system will generate a unique ConfigMgr GUID and will function as expected.

For step number 5, this can be achieved by using the wbemtest tool with the following steps:

  • Launch wbemtest as Administrator
  • Click Connect
  • Change the Namespace field as root\ccm\invagt, and click Connect
  • Click on Enum Classes
  • Select Recursive and click Ok
  • Scroll down and locate InventoryActionStatus, and double click
  • Click on the Instances button
  • Select the Inventory GUID and click Delete
