M365 - Basic Auth with SMTP AUTH retiring

[Oliver_Nash]

Microsoft have stated they’re retiring basic auth for SMTP early next year (starting March 1st 2026 and completing by April 30th 2026).

Given the widespread use of M365, will QuickFile be supporting the use of M365 via modern authentication standards instead?

Many thanks,
Oliver

Hi @Oliver_Nash

This isn’t something that we’ve planned at the moment.

However, you’re welcome to start a Feature Request if you wish, and we can post any updates there.

Here’s a link to the feature request if anyone wants it:

Microsoft 365 Email - OAuth Support

*Microsoft have announced that they’re retiring basic auth for SMTP early next year (starting 1st March 2026 and completing by 30th April 2026). Once this change is made, the current SMTP connection to QuickFile will stop working and we’ll be unable to send emails out via M365. This feature request is for QF to provide support for modern auth options to allow continued use of M365 for email services with QF once this change is implemented.*
