Dear Brad,

   the issue is that the refresh token was revoked by the server. Who knows 
why that happen. It was an internal policy. Tokens can be revoked for 
several reasons, including, but not limited to, expiration: The refresh 
token has outlived its validity; change in account settings: for example, 
change in the password; confirmation of account settings: checking that 
your information is up-to-date. Apparently you hit another one: not loging 
into your account for a week.

   When this happens simply try to reopen your INBOX. For example, if the 
error happens when you are opening Alpine, a failure to open your inbox 
will put you in a screen from where you need to navigate to your INBOX and 
then try to open int again. This time Alpine will display the screen to 
grant authorization to Alpine and create the refresh token  that you can 
use in the future.

The refresh token that is used to login to your inbox is the same that is 
used to login to your smtp server. Revocation of the refresh token will 
prevent you from reading your inbox and sending email. It is an "all or 
none" scheme.

I hope this helps.
