Working with a shared Exchange account has a major issue when it comes to handling sent emails.
When you forward, or reply to an email from the shared account the sent mail ends up in the users personal Sent Items folder. This takes away the biggest advantage of a shared mailbox: knowing who answered to an email and knowing what was answered.
MailMover takes care of this problem, it automatically searches for the correct mailbox and places the reply, forward or new mail that was sent on behalf of that mailbox in it's Sent Items folder instead of in the users personal Sent Items folder.
Download the demo version and test for yourself. The only limitation to the demo version is that the name of the shared mailbox has to contain the word "demo". The full version has no limitations at all and can be used on as many computers as you want!
