Outlook Add-in Missing

Dear all

 

I am unable to make the Outlook plugin work for one of our employees. I know where the plugin-in is located on the computer and when I add it manually - nothing happens. I have also reformatted the entire computer but to no avail.

 

Can other plugins interfere with the proper loading of the Teams plugin? 

 

Do you have any suggestions on what I can do? 

 

Thanks

 

Massimo

    mscola   I know this is a late REPLY to your message, but I just had the same symptom occur today.  I closed Outlook and logged out of Teams.  I logged back into Teams, opened Outlook, and the plug was enabled and it shows "Teams Meetings" when I create a new meeting request.

     

    The symptom started right after I tried to install Visio.  The install failed, and I lost all the O365 file extension associations.  I re-loaded O365, then I loaded Visio successfully.  That is when I noticed that the "Teams Meeting" plug was missing.  Teams wasn't even listed as an available add-in.

     

    Also - we are still using Skype For Business, and we are in "Islands" mode in the Teams Org Settings.  

     

    I am running O365, v 16.0.13001.20266 and MS Teams v 1.3.00.13565

     

    ...anyhow - just sharing my experience for others.  hope it helps!

    If a user switched in the Microsoft Teams App to another tenant, the Outlook plugin for Microsoft Teams is hidden. As soon as the user is back in the "home" tenant, the Outlook plugin should be available.

      Achim_Bossler Hi Achim

       

      What tenant are you talking about? 

       

      I have even reset this user's computer - yet he is still unable to see the plugin. 

       

      Thanks

        I'm talking about the case, where a user is a member of at least two tenants:

        • member of the "home" tenant
        • external guest of any tenant

      This was my issue. User was a member of an external team. Had her switch Teams to her (our) office account and then close/reopen outlook and the start meeting icon reappeared. We've also advised users to be sure to be logged into their (our) office account before connecting to outside teams meeting they were invited to. Otherwise, they can't connect to the meeting as it is trying to connect with their guest teams account.

    A method which I use to resolve this which generally tends to work is the below:

     

    1. Navigate to C:\Users\*****\AppData\Local\Microsoft

    *** Being the user who is having issues

    2. Delete the MicrosoftTeamsAddin folder

    3. Copy the file from another users account which works

    4. Reopen outlook and check to see if Teams addin is within com addins

     

    If this doesn't work I have used the below:

     

    1. Close outlook

    2. Open CMD as Admin

    3. cd C:\Users\*****\AppData\Local\Microsoft\TeamsMeetingAddin\1.0.20107\x86 (Addin version number may be different)

    4. regsvr32 Microsoft.Teams.AddinLoader.dll

    5. Restart machine

     

    Now this doesn't work 100% of the time but I have found this to work in most cases.

    If the add-in is listed under Inactive, make sure "COM Add-ins" is selected in the "Manage" drop-down and click "Go...". Check the checkbox next to the Add-in and click "OK". Restart Outlook. Close Outlook, wait for 5 seconds, then start it again.

    This May Help,
    Peter
