I have a client using hosted exchange and there are 2 mailboxes that I would like them to have access to. I believe I have found 2 ways to do this in exchange 2010 and outlook 2010.
1. establish main mailbox then give the person full access to the 2nd box in exchange and then add it under the "open addional mailboxes tab"
2. establish main mailbox, then add another account and add the 2nd mailbox.
Both seem to work fine although I feel like the second option works better. Is there any downside to doing it this way?
