Hello, I'm trying to use MailMate r5875 with Office365 using OAuth2 to authenticate for both IMAP and SMTP.
IMAP works fine. When I use SMTP, the server refuses MailMate's attempt to authenticate as follows: 11:17:22 Retrieving password (keychain or user request) 11:17:22 C: AUTH XOAUTH2 •••••••••• 11:17:27 S: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Tenant. Visit https://aka.ms/smtp_auth_disabled for more information. [AM4PR0701CA0035.eurprd07.prod.outlook.com] 11:17:27 Error: Unexpected return code 535 (expected 235): “5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Tenant. Visit https://aka.ms/smtp_auth_disabled for more information. [AM4PR0701CA0035.eurprd07.prod.outlook.com]”. 11:17:27 Error code: 2000 (There's a full log of the session at the bottom of this mail in case that's helpful). My employer has provided special instructions for configuring Evolution on Linux to work with our Office365 system. These include overriding the Tenant and Application ID settings — there's an example of what that looks like at https://urchin.earth.li/~jds/evolution-oauth2.png. Perhaps something similar is necessary in MailMate - is that possible? Any ideas or suggestions much appreciated!
