MailBot by Tavel — email accounts creator, checker and unlocker

MailBot has been updated to version 16.57.

This article is a continuation of the previous one, about adapting MailBot to mandatory authentication via OAuth2 for Outlook mail servers.

A new setting “Generate OAuth2 refresh token” has been added to the “Email Features” tab:

This setting currently only works for the Outlook/Hotmail module. If the checkbox is checked, the Outlook creator will generate OAuth2 tokens for accessing mail protocols after successfully creating an account, and the checker will generate them after successfully logging into an existing account.

Attention! All OAuth2 tokens are generated for ClientId 9e5f94bc-e8a4-4e73-b8be-63364c29d753, which is the ClientId of the Mozilla ThunderBird IMAP client in Outlook.

After successfully receiving OAuth2 tokens, MailBot will append a refresh token string to the end of the account string, and will also additionally save all parameters received from the OAuth2 server to a JSON file in the “oauth2” folder inside the “Accounts” folder. The file name will match the account email address. Example of the contents Read more »

MailBot has been updated to version 16.54.

Since September 20, 2024, Microsoft has almost completely disabled authentication via regular password (PLAIN method) on its IMAP, SMTP and POP3 servers, leaving only the OAuth2 option (XOAUTH2 method). As of today, only a few servers remain unpatched, and it is almost impossible to authenticate with a regular password on Outlook mail servers.

If you try to authenticate with a regular password, for example, the Outlook SMTP server will respond with this error:

535 5.7.139 Authentication unsuccessful, basic authentication is disabled.

and the Outlook IMAP server will respond with this one:

001 NO AUTHENTICATE failed.

To some extent, this also affected MailBot, since the verification of recovery emails in the program is carried out via the IMAP protocol.

In connection with this, a new setting “Authentication” appeared in the recovery email source settings window in MailBot, which is a list with two values:

• Plain password
• OAuth2

When connecting Outlook accounts as recovery emails, you now need to select only OAuth2, and the format of the recovery emails in the file should look like Read more »
