I have exchange 2010 SP1 and I am trying to add a mailbox under recipient configuration. The user
I want to add isn't in the list of objects. So I start to add him and select create mailbox for existing user. I can locate him and select him and at the end I get Error: Property Expression " name of user" isn't valid. Valid values are: Strings that includes '@' where '@' cannot be the last character.


Thanks,

Is there a @ in the username? Remove the @ using Active Directory Users and Computers

No @ in the username. The user doesn't show up under mailbox. He is in active directory but just doesn't show up under mailbox. So I need to and him  But if you try to add him and select existing user then you can select him and try to complete the wizard you get that error i described.

Problems using Powershell and Active Directory?

No @ symbol for alias.

Have a look at that account in ADSIEDIT and see if there is a @ symbol present in distinguishedName or any of the other values. UserprincipalName should have one, but it should not be on the start nor end of the value.

After using ADSIEDIT I only found one @ symbol and that is for email. Nowhere else.

Apparently this can occur if there is a space at the beginning of the username or user alias. Check/change it with ADSIEdit

Found Solution to problem. The users I couldn't create mailboxes for is due to their accounts in active directory. Each account didn't have @domain.com under their logon id.

Thanks,
