"Houston, we have a solution."
More like replacing one problem with another. My #thunderbird was taking 10 seconds to handshake and read my outlook mail. I switched to #betterbird and that problem disappeared.
If you look at all the outstanding bug requests on #tbird, you'll see why #Mozilla products are no longer the browser/email client of choice.
I may not have noted in my original post, but I have tried both TB and BB many times over several weeks including TB updates and in all instances TB did not work and BB did.
So I think it's a fair assumption that the problem is with TB. They must have made a change in their fork that BB did not.
And as I said, if I keep trying TB updates it will probably be fixed at some point and I can continue using TB then.
