Hi, I am a longtime Thunderbird user. I am using the latest update of the software. Suddenly, out of the blue, I am getting this error message on just ONE email account. The account *** is being processed. Please wait until processing is complete to get messages. I have 3 other email accounts which are downloading normally. I have not made any changes to my computer/Thunderbird or done anything different. I just opened mail this morning and have had the issue all day long. Thanks in advance for any help!
