outlookopen with error code 80090016
Last Updated a year ago

The solution for me was to rename this folder:


This needs to be done with the affected user logged off, i.e log on as a different admin user or do it from a network share. the folder will get recreated when the user logs on next.

Start Outlook, you will need to enter password again, you will get asked to workplace join again "say yes to allow my organization to manage this device" it may still throw the 'Something went wrong, TPM error' but ignore this and Outlook should continue to load again. The TPM error will only occur once.

I have tested this on many different affected systems with 100% success rate
