My Support employee has changed settings for a customer with Exchange ECP. after he has saved the changes the UPN of the customer is lost and changed to the default internal (AD) domain name.

Is their a way to fix this behavior of exchange without adding the domain to AD's Domain and Trust?

i personally don't mind because i use powershell, but from the support / service desk site looking i can see some issues in this.

additional: with this problem also the user cant login to RDS, Reason: the specified user account does not exist.

Kind Regards,

Robin

Hello,

Do you have your OWA virtual directory set to authencitation --> UPN ? (instead of the default)

That should normally fix this problem.

Marco

Hi Marco,

Thanks for your quick answer, i've changed from default to UPN after this iisreset, but problem remain the same form the ECP side.

Hey Robin,

you can set the login name of the user in the SolidCP mailbox page to the previous UPN and then save this mailbox in SolidCP. This will set the default UPN for this User back.

I don’t think it’s possible to Safe the mailbox in ECP without adding this domain to AD. ECP shows only these domains and if it won’t find it, it will set it to the local domain, which will break the UPN.

Best regards

Bogdan
