Do you accept cookies in TB Settings/Privacy & Security? It's required to complete the OAuth authentication.

Hello ! Thanks to all the benevolents and contributors. TB would not be the same without them. I had the same PB and while I did not modify anything myself, I have noticed that instability is causing some unwanted mod. How could that be corrrected ? It was - in fact - the cookies setting in TB ! Has to be allowed ! Well spotted. Since putting it back to work, it does cross the whole name of any "incoming" mail when moving or deleting it. Any idea ? Thanks again Alain

The recommended setting for gmail IMAP accounts is to 'Just mark it as deleted' in Server Settings, so when you delete a message, it appears in the message list with a strikethrough, and disappears from view at the next synchronization, or next time the folder is opened.
