I'm having a problem with an Outlook 2010 client. I have added an additional mailbox to an Exchange account. This is the second of two additional mailboxes; the first additional mailbox works fine and I can browse and read email in the box. However the second mailbox shows only the folder with no mail, until I click Send / Receive -> Update Folders, then it downloads fine and I can read the mail. When I turn off shared folder caching it works fine.
I've also tried a new mail profile but the same thing happens with the new mail profile.
Any ideas?
