Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
This morning, I contacted Microsoft Support, and a technician helped me with this issue. Remember this is on a Windows 11 with Microsoft 365. It's a fairly easy solution.
Hold down the Windows key + R
Type: %localappdata%
Open the Microsoft folder
Delete the Identity folder
In Search on the Task Bar type: appwiz.cpl (or just Un/Install in Control Panel)
look for: Microsoft 365 - en-us and right click on it
click on: change
Choose: Online Repair
It will do a repair and a download, and it was okay again.
Many thanks to the Microsoft technician who did a remote fix on my computer!
PS: I also had a Windows 10 laptop and it's about the same. Only the "Identity" folder was called "IdentityCache".
