Hello! As of midnight last night, one of my Thunderbird IMAP accounts has started giving me this error message - "Server x has disconnected. The server may have gone down or there may be a network problem." Now, both of my accounts go through Gmail - though one is a Google Business Apps account (and that's the one that's not working). Both accounts are accessible online, the servers are NOT down. So far, I've removed the account and added it back, no change. I've uninstalled Thunderbird and reinstalled it, added the accounts back, no change. I don't run any of the anit-virus software that's been mentioned in other incidents and I had no major changes to my system last night that should be causing this. Help! Jer
