As we proceed with our Exchange 2010 migration, I discovered that some mailboxes appear corrupted to powershell users, resulting in this error:
[PS] C:\>get-mailbox -identity rmurphy WARNING: The object ad.acadiau.ca/academic/rmurphy has been corrupted, and it's in an inconsistent state. The following validation errors happened: WARNING: Property expression "rmurphy" isn't valid. Valid values are: Strings that includes '@', where '@' cannot be the last character After some digging I discovered that the AD account attribute UserPrincipleName does not have a domain associated with it (e.g. 'rmurphy' instead of 'rmur...@domain'). This can be fixed easily in ADUC under the Account tab, but with over 100 users in this state I'd like to find a programmatic way of doing it. I could whip together a C# or VB script to fix the problem, but I was wondering if this sort of thing could be done in PowerShell. I'm still learning PS but from what I've seen I think the answer is yes. Anyone PowerShell experts out there?
