11/13/2025, 2:52 PMOK am I losing the plot here - does the "new" Teams use some different add-in for Outlook than the old one did? Got a customer who keeps seeing the Outlook and Teams integration just "disappear" after they log on to their VDIs.....

11/13/2025, 4:36 PMManaged to sort this out. Set up an Ivanti job to re-register the Teams add-in DLL at every reboot and it seems to have brought it back. Trying to work out what "new" and "old" Teams need is a nightmare - and don't, for the love of God, ask an AI platform, or it will send you down a rabbit hole
