Trouble connecting with IMAP + Microsoft365 (business)

[kimowasabiii]

Hi all,

I’m having trouble connecting the IMAP credentials with a business Microsoft365 account. The error simply reads:

"LOGIN failed"

Using:

• outlook.office365.com
• Port 993
• SSL/TLS.

Has anyone experience fixing this?

Thanks in advance!
Matt

Found this thread, but seems unresolved:

Hey @onurbolaca, Another quick one… @MutedJam has just reminded me about this : Deprecation of Basic authentication in Exchange Online | Microsoft Learn It could be that you just can’t use the IMAP node anymore because of this change and you will have to use the schedule and outlook node to do the same thing.

The FAQ in this documentation doesn’t seem to support business accounts.

Hey @kimowasabiii,

The error message you are seeing is coming back from Microsoft, They are moving away from IMAP support so you may need to use a different approach like the Outlook trigger node we have instead.
