Exchange: The execution of cmdlet Set-SyncMailUser failed.
Hi. We have a hybrid environment and recently we've encountered a problem on converting a disabled email account to shared mailbox. It was shown this error message:
Exchange: The execution of cmdlet Set-SyncMailUser failed..; Exchange: An unknown error has occurred. Refer to correlation ID...
The mailbox was disabled on the on-prem EAC and cannot be seen on the exchange online EAC so I suspect there was a problem in it. I've found that the above error can be caused by a guid conflict between the online AAD and the on-prem server and I tried the powershell in https://www.risual.com/2019/03/exchange-online-unknown-error-has-occurred-in-hybrid-environment/ but when I typed
Enable-RemoteMailbox “example.user@domain.com” -RemoteRoutingAddress “example.user@domain.onmicrosoft.com” -PrimarySMTPAddress “example.user@domain.com”
, there will be an error saying that:
This task does not support recipients of this type. The specified recipient <user> is of type RemoteUserMailbox. Please make sure that this recipient matches the required recipient type for this task.
get-recipient <username> returns
Name RecipientType
---- -------------
<Username> MailUser
---- -------------
<Username> MailUser
I don't know where to go from now. Does anyone knows how to fix this error? Thanks.
Thierry Chapuisat At last I hard-matched the guid between Azure and the on-prem ad.

- Hi,
Did you try the Scenario 1 ?? :
https://docs.microsoft.com/en-us/exchange/troubleshoot/user-and-shared-mailboxes/mailbox-exists-exo-onpremisesThierry Chapuisat I guess so since the cmdlet in scenario 1 is similar to what I followed in the guide. However, the cmdlet
Enable-RemoteMailbox "user identity" -RemoteRoutingAddress "user@contoso.mail.onmicrosoft.com"Failed and the error
