Hi All,
after excute this command
Enable-UMMailbox -Extensions 100 -SIPResourceIdentifier "testuser1@domain.com" -Identity "domain\TestUser1" -UMMailboxPolicy "UMMailboxPolicy"
error appeared and it seems no one has error before "
Unified Messaging can't validate or generate a UM PIN for mailbox 'Test@noorsat.com' : An error occurred while accessing the
user's mailbox. Details: The request failed with HTTP status 405: Method Not Allowed"
please advice?
