Answer 1

Hello @Vishal Shukla,

Good day! I hope you are doing well. 

Based on your description, I understand that the Microsoft Teams Meeting add‑in is missing or no longer visible in your Classic Outlook after reinstalling Microsoft Office and Microsoft Teams. 

Please note that the Microsoft Teams Meeting Add‑in for Outlook does not have a separate MSI installer. The add‑in is installed and registered when all eligibility and configuration requirements are met. Because of this, the issue is usually related to eligibility, licensing, configuration, or registration rather than a missing download file. 

For your reference: Use add-ins in Outlook - Microsoft Support 

Here are a few steps you may want to try to resolve the issue: 

Step 1: Confirm eligibility requirements 

Please verify that the following requirements are met: 

• You have a valid Microsoft 365 subscription that includes Microsoft Teams 
• A Teams license is assigned to your account 
• You are using Classic Outlook for Windows (Outlook 2013 or later) 
• The Microsoft Teams desktop client is installed on the same machine as Outlook 
• You are signed in to Teams using a work or school account 

If you are using New Outlook for Windows, the Teams meeting capability is built in, and the COM add‑in will not appear. This is expected behavior. 

Step 2: Check whether the add‑in is installed but disabled 

In Classic Outlook, please check the following: 

• Open Outlook 
• Go to File > Options > Add‑ins 
• At the bottom, set Manage to COM Add‑ins and select Go 
• Look for Microsoft Teams Meeting Add‑in for Microsoft Office 
• If it appears but is unchecked, enable it and restart Outlook 

Outlook may automatically disable add‑ins if it detects performance or stability issues. You can also go to Disable Items > Go... and check whether this add-in is disabled and re-enable it if you want. 

Step 3: Ensure Outlook and Teams are running in the same context 

The add‑in will not load if Outlook and Teams are running under different privilege levels. 

• Right‑click the Outlook shortcut > Properties > Compatibility 
• Right‑click the Teams shortcut > Properties > Compatibility 
• Ensure “Run this program as administrator” is unchecked for both applications 

Then fully close both apps, start Microsoft Teams first, sign in, and then open Outlook. 

Step 4: Reinstall Microsoft Teams to re‑register the add‑in 

If the add‑in is still missing: 

• Fully close Outlook and Teams 
• Uninstall Microsoft Teams from Settings > Apps: Uninstall Microsoft Teams - Microsoft Support 
• Download and install the latest Teams desktop client: Download Teams Desktop and Mobile Apps | Microsoft Teams 
• Restart your device. 
• Launch Teams, sign in, then open Outlook 

Reinstalling Teams re‑registers the Teams Meeting add‑in with Outlook. 

For your reference: Understanding the Microsoft Teams Meeting Add-in for Outlook: Eligibility, Issues, and Troubleshoot… 

If the issue persists after the steps above, contact your IT administrator for further investigation. Ask them to: 

• Confirm the add‑in has not been disabled by tenant or group policy 
• Check for corrupted user profiles or registry entries 
• Consider manual add‑in registration 

If needed, they can help you open a support ticket using this instruction: Get support - Microsoft 365 admin | Microsoft Learn 

Please let me know if you need any further assistance. Thank you and wish you a nice day!

Answer 2

There is no separate MSI download for the Teams Meeting add‑in for Outlook. The add‑in is installed and registered automatically by the Microsoft Teams desktop client and surfaced in Outlook if eligibility and configuration requirements are met.

To restore the add‑in, use these steps instead of looking for an MSI:

1. Verify the add‑in status in Outlook
   1. In Outlook, go to File > Options > Add-ins.
   2. At the bottom, under Manage, select COM Add-ins and choose Go.
   3. Look for Microsoft Teams Meeting Add-in for Microsoft Office.
   4. If it appears but is unchecked, check it and select OK, then restart Outlook.
2. Make sure Outlook and Teams are running in the same context
   1. Right‑click the Outlook shortcut > Properties > Compatibility and ensure Run this program as an administrator is unchecked.
   2. Do the same for the Teams shortcut.
3. Restart Teams and Outlook in the correct order
   1. Fully quit both apps.
   2. Start Microsoft Teams first and sign in with a valid commercial account.
   3. Then start Outlook and check again under File > Options > Add-ins.
4. Reinstall the Teams desktop client to re‑register the add‑in
   1. Close Outlook and Teams.
   2. Uninstall Teams via Settings > Apps.
   3. Install the latest Teams desktop client from the official Microsoft Teams download page.
   4. Restart Windows.
   5. Launch Teams (sign in), then open Outlook and recheck the COM Add‑ins list.
5. If the add‑in is still missing, follow advanced/IT steps
   • For classic Outlook, admins can:
     • Confirm the add‑in is not disabled by policy.
     • Reregister the add‑in loader DLL as documented in Resolve issues that affect the Teams Meeting add-in for classic Outlook.
   • If using the new Outlook for Windows, note that it does not use the legacy COM add‑in; it has a built‑in Teams meeting capability instead. If that is missing, see Teams meeting add-in missing in new Outlook from the same documentation set.

If these steps do not restore the add‑in, escalation to an IT admin or Microsoft support is recommended to check for tenant policies, mailbox configuration, or registry/profile corruption.
