We recently upgraded from Exchange 5.5 SP4 to Exchange 2003 SP1. Now, when people access a shared mailbox in their Outlook configuration and reply or forward messages in the shared mailboxes folders, the From: address is changed.
In Exchange 5.5, the From: address field was automatically set to the user of the primary mailbox. Everyone is used to this, and is comfortable with how this works.
Now, with Exchange 2003, the From: address field is being changed to the user of the shared mailbox, and has to be manually changed to the primary mailbox user in order for it to behave the way it did in Exchange 5.5
Everyone is complaining about this, and Microsoft's support site is coming up short on this topic. I'm hoping that you geniouses have seen this (how could you not have?) before and know how to fix it or work around it more elegantly than telling everyone to manually change the From: address.
Any help or hints would be greatly appreciated!
