ThunderBird :
Message when asking for mail :
Get this message (nearly) every time I start Thunderbird.
Have checked settings - seem OK
Some years ago I changed (reluctantly) to GMail with another client, but wanted to get back to TB and so recently I have - as yet just a backup.
ThunderBird 600.0 (32-bit)
Windows 10 - fully updated.
You'll notice that this eMail address is not the one I'm asking about, because I may not get it!
