When I migrate a mailbox from Exchange 2003 to Exchnage 2007 that has permissions set to allow other users to access it, it is created in Exchange 2007 as a Shared Mailbox. No big deal as I use EMS to switch it back to Regular. But, if the user account has its password set to never expire, the switch from Shared to Regular resets that setting to expire and the user is prompted to change his password the next time he logs on. I use this cmdlet to switch the mailbox type: Set-Mailbox -Identity 'display name' -Type 'Regular'. Am I doing something wrong, or is this a cause and affect that I will just have to deal with? Thank you.
