I get the infamous "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections" error in Thunderbird. I just moved to a new Windows 11 laptop but have signed-off the old unit and old phones, leaving just two devices in Google / Security. Obviously, I have reduced the IMAP connections to 1 on the PC. Still, I cannot get emails on this new PC; before reducing the devices, I could get emails on the old PC, the new phone, an iPhone, and an old phone. Turning off the fire wall does not help. I have done many variations of uninstalls / reinstalls on likely combinations of devices. I won't repeat those here but the net outcome seems to be: uninstalled / reinstalled Thunderbird - no effect shut down new computer and fired up old computer and Thunderbird retrieved new messages immediately downloaded and installed eM Client - immediately connected and retrieved new messages downloaded and installed MailBird - immediately connected and retrieved new messages started Thunderbird and received the too many message. I just finished a round of installing / reinstalling Thunderbird but with all the AppData/Thunderbird/ folders / profiles deleted. The Wizard failed to identify the server information, which I supplied based on the three sets of working parameters (Tbird, eM, MailBird) but the error this time was a could not connect due to the Username and Password not agreeing. I don't want to give up Thunderbird but I am out of patience. Please advise if there is some hope for a software fix. I have wasted too much time on this already pursuing a universe of possibilities. Thanks, Don
