Unable to set permission using ECP. Error 5 Multiple objects with Sid S-1-5-32-544 were found
Hi all,
we are using Exchange 2019 on prem and since a week we are unable to set mailbox permission using ECP in any mailbox: We can open mailbox details but when choosing mailbox delegation, a popup "try again later" is logged. also Event 5 in eventlog is raised with "Multiple objects with Sid S-1-5-32-544 were found".
Powershell is working!
I checked all mailboxes getting permission detailes but I am unable to find any problem.
Any hints?

Gernot_Meyer We had this occur with 2 shared mailboxes. Turns out there were 2 objects for user S-1-5-32-544 and 2 objects for user S-1-5-32-548 using Get-ADPermissions (548 may show up in your event log after you fix the 544 issue). We used the following to determine the existence of the extra object:
Get-Mailbox mailboxid | Get-ADPermission -User S-1-5-32-544 | fl extendedrights,accessrights
which showed 2 objects. One object was solely for Send As permission. We used the following to remove the extra object:
Get-Mailbox mailboxid | Remove-ADPermission -User S-1-5-32-544 -ExtendedRights "Send-As"
If you still have the error, repeat using SID S-1-5-32-548 or whatever SID is at issue.
