Running GW 14 SP 2.
Everything works fine on the other accounts, but 1 account, MINE!, refuses to update it's caching mailbox. Everything's fine in online mode, I've removed the client, deleted the cache folder and reinstalled. It worked for a day, then stopped updating. Everything appears fine, just no new mail. There are no pending requests on the system, but GWcheck's logs shows 74 pending requests for just that user. I've deleted the index folder, recreated it, but to no avail. I think it may be corruption somewhere, as it worked before the UPS was accidentally turned off, while the servers were running.

Does anyone have an suggestions?
