I've been trying to figure this out for months, but I don't always have the problem... so I forget to ask about it.
I use Entourage on OS X for my work, and I have an Exchange account.
Usually, when I launch Entourage, the client automatically connects to the server, and everything's fine.
Sometimes... like if I lose my internet connection and Entourage is running, when I get the connection back, Entourage refuses to connect back to the Exchange Server. Sometimes quiting and relaunching will solve this... at launch, if the connection is there, Entourage connects back to the server.
Sometimes... it just doesn't, even though I know there is an internet connection, or I'm even on the same LAN as the server.
Entourage has a "Work Offline" under the Entourage menu, but AFAIK... there is no button or menu task that forces Entourage to connect to the Exchange server. When Entourage doesn't connect to the server, next to my account, it just says (Not Connected), and it just sits there, sometimes fixing its connection, sometimes staying that way indefinately.
This is driving me nuts.
How do I force Entourage to connect to the friggin' Exchange server???!!!
