Issue
Teams version 1.5.0.17656 was installed using an exe file from the Teams Download site. No matter how often you update, uninstall, or reinstall, there seems to be no change in the behavior at launch. Teams 1.2.x is present on the machine and keeps looping.
1. Tried to remove it using RevoUninstaller, and all artifacts
2. Manually scavenged any temporary folders and blew them away
Solution
The device originally came with ‘Teams System-Wide Installer,’ which was removed manually from add/remove as bloatware in past years. Reintroducing the ‘ Teams Machine-Wide Installer‘ fixed it instantly with no other changes to the machine.
Reboot the device now.
Have you run into any other fixes for this issue? Let me know. I threw the kitchen sink at it and could only get this to work by reintroducing the baseline installer in the image.
