Windows 7, Outlook 2010, IMAP settings with a mail and domain host provider (NOT GOOGLE). Mails are coming and going ok. Also IMAP folders are syncronised. But sometimes (many times) have reported error (0x800CCC0E): "Outlook cannot synchronize subscribed
folders". This case no connections to the server and if I click on "Connect to the server" icon also I get an error message: "It is impossible to connect to the server" or something.
It was the same issue on the same PC with the same account configured in Thunderbird v19. The parameter mail.server.server1.max_cached_connections change from 5 (default) to 1 has solved the problem. Could it be something in Outlook?
