0x80004005 error help

[dmcdonald]

I have an exchange account and a pop account set up through outlook 2007. The pop account will stop receiving email at a certain point and the error above will come up. If I restart the machine, everything starts working and email comes in. The primary problem is that the pop account stops receiving mail at the same time this error code appears. The user would like to leave the computer turned on overnight periodically without the risk of not receiving email to the pop account or the error. The computer is connected to a local network as an exhange user.

Thanks for any help!
