Fixing Entourage inbox
My Entourage inbox stopped updating! Everything else (sent items, junk folder, etc.) was updating fine. The lazyweb led me to the following fix: Empty the Inbox cache.
Right-click Inbox folder, select Folder Properties. “Empty Cache” is in the middle of the General pane. Read the warnings, then click Empty.
This empties your inbox folder, which then gets repopulated from the Exchange server on the next sync.
