Hello,

 

Just a quick post to inform the community that I was able to fix my issue thanks to a https://supertekboy.com/2021/07/21/former-calendar-delegate-still-receives-meeting-notifications/ by Gareth Gudger. When you search the web for this issue, you find a lot of articles pointing to MFCMAPI but all you need is just PowerShell 😉

The delegate hidden rule redirecting to the user has now been cleaned up. 

I hope this can help other people with the same issue.

Thank you @Gareth Gudger, you made my day!

Could you identify the specific powershell command you used to resolve this? We have the exact problem with our CIO's mailbox and he woukd certainly appreciate a resolution. Thank you!
