I always seem to get the weird problems with Exchange 2010...
I have created all the users for a new domain. The users all set up with no problems, but now when I try to create mailboxes for them, I get two different errors:
If I try to select multiple users and create mailboxes for them, I get the following error for each user:
"The property value is invalid. The value can't contain leading or trailing whitespace.
Exchange Management Shell command attempted:
'<domain>/<OU>/<user> ' | Enable-Mailbox"
I also get a whitespace error if I try to do an enable-mailbox from the Exchange command shell.
If I try and create a mailbox for a single user, right after I select the user from the list and go to the next step, I get the following error:
"MMC has detected an error in a snap-in and will unload it".
I have been through every property in the user account in ADUC and I don't see any whitespace. Any ideas?
