Microsoft is disabling support for Basic Authentication for some protocols in O365. This is happening on a random basis for tenants from October 1st, 2022. For more information from Microsoft, read here.

What does this mean for SpamTitan? 

If you have configured SpamTitan to perform authentication to the UI using IMAP, and you are authenticating against O365, your users may no longer able to log into SpamTitan (for example, to view their quarantine) once this change takes effect on your tenant.

Step-by-Step Solution

If you are using IMAP authentication, the following options are available:

  • Use a one-time re-enablement that will allow you to continue using IMAP until January 2023, at which time you must switch to an alternative authentication method. Click here to learn more.


The only resolution to this is to switch to an alternative authentication method in SpamTitan. You can do this from Settings > Access / Authentication > Web Authentication

See here for more information on configuring alternative authentication methods.
