The ACE does not Exist on the Object- Office 365

Yesterday, when i was trying to remove full permission from one of the my online user's mailbox and getting below error "BECAUSE THE ACE DOESN'T EXIST ON THE OBJECT"


Root Cause of the warning is, orphaned SID is pending on the mailbox, which is conflicting with rest all delegate user's permissions.

Solution

Simply we need to remove the SID first, and you have permanently resolved the issue.

Below cmdlet which we can eliminate the things, Get the orphaned SID. Run below cmdlet.

Get-Mailboxpermission -identity abc@domain.com | select user | fl

Run below mentioned command, and remove entry of orphaned SID from User Beta's mailbox.

Remove-Mailboxpermission -identity abc@domain.com -user "SID which we got" -Accessright fullaccess

Once done, we have to give the time for sync to Office 365.

Happy Learning!
