Hello,

we created a guest account to share a file, but we had a problem. There Are two exchange contact was created and I can’t suppress there. Mail can’t be deliver to this external contact with this error :

Reason: [{LED=420 4.2.0 Transient Failure during recipients lookup AmbiguousRecipientTransientException, Exception of type ‘Microsoft.Exchange.Transport.Categorizer.AmbiguousRecipientTransientException’ was thrown.};{MSG=};{FQDN=};{IP=};{LRT=}]

I could suppress Guest account on Entra ID, and I did, but I have already this two Exchange Mail contact account.

I used graphic interface and powershell commande :

Remove-Mailcontact -Identity “rholdXXXXXXXX”

Write-ErrorMessage : Ex6F9304|Microsoft.Exchange.Configuration.Tasks.ManagementObjectNotFoundException|Impossible d’effectuer l’opération, car l’objet ‘rhoXXXXXXX est introuvable
