Thunderbird v. 91.8.1 MacOSX Monterey 12.3.1 I keep getting this error message. "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server. If so use the Advanced IMAP Server Settings dialog to reduce the number of cached connections" I have reduce the connections in 'Advanced' Server settings' to 1 but the problem persists. Can you advise please? Regards, Philip Bergman
