I have a user whose teams add in keeps on disappearing from outlook calendar to create new meetings. What I have done is go to Applications and uninstall Microsoft Teams meeting add-in for Microsoft office then quit teams and close outlook. Relaunch teams so the add-in auto installs when I open outlook the meeting invite is back on the calendar. This has happened 3 times within a few weeks of each other. I have not been able to find any other fixes. Does anyone know of a more permanent solution?

    Hi,

    The Teams add-in keeps disappearing because Outlook disables it when it detects performance issues or because updates reset its load behavior.

     

    Permanent Fix:

    In Outlook, re-enable the add-in under File > Options > Add-ins if disabled.

    Repair Office and Teams, and ensure both apps are fully updated.

    If in a managed environment, confirm no Group Policy is disabling the add-in.

     

    Doing these steps usually prevents the add-in from disappearing again. I hope this helps!
