We have a Windows SBS 2008 with Exchange 2007. One user has a 2.6GB mailbox we are trying to import into the mailstore via Outlook 2007 using non-cached Exchange mode, however at 2GB it stops with the message 'Message store has reached its maximum size'.
However we have cleared the size limits in Exchange, both in the Mailstore defaults and in the user's own mailbox, yet the problem persists. The entire mailstore in Exchange is only at 5GB so it's not like to store is too small, and there is plenty of space available on the disk. Any ideas?
