I have a single user who is only able to log in via premium client. I have not had her test other workstations in her area, but all other users in her area are able to get Premium and I gave myself rights to her mailbox and when I open her mailbox from my desktop I also get light client (whereas my mailbox goes to premium with no problems).
I have tried the powershell command "Get-CASMailbox -identity username |FL OWAPremiumClientEnabled" to see if premium client is enabled for her and it comes back $true
I even tried "Set-CASMailbox -identity username OWAPremiumClientEnabled:$true"
and "Set-Mailbox UserName -ApplyMandatoryProperties" (just to be sure - lol) and each of those came back with the message that no properties had been changed, of course.
We are running Exchange 2007, SP1 on Windows 2003 Enterprise R2, 64-bit, SP2, and users are running XP client.
Open to any suggestions...
