Here's a link to a prior Sage City post which discussed setup in more detail. You may have already seen this - www.sagecity.com/.../microsoft-o365-email-and-oauth-setup-in-paperless-office

I saw that post; the patches are for failed login and send. I can login and send the email, but Sage requires I enter the login every time I want to send a paperless office email. From my reading I am using 2022 SP2 or am I wrong. Note: I used an admin account to register the O365 app.

You need to add the offline_access scope to your existing scope. E.g.

"outlook.office.com/SMTP.Send offline_access"

Without the offline_access scope, you won't get a refresh token and will be forced to authenticate on each use, as you have already noted.

That fixed it for me.

Thank you very much.

I have noted that I get an error if I don't check both PDF and EMAIL, but the EMAIL is sent.
