Mitchell ShollyWe've had a small number of our clients report that the Microsoft Teams add-in for Outlook may be affecting Out'n About! and other add-ins. If you are having add-in loading issues after installing Microsoft Teams, please check you are running the latest version of Teams add-in or disable the add-in entirely, if it's not critical to your users. This is a developing issue, and may be limited to only certain environments. This post will be updated when we learn more.
