currently I monitor our Mail-Delivery-Process towards Microsoft Outlook with the active-check “Check Email Delivery” (active_checks[“mail_loop”]). It uses IMAP as protocol, which is fine so far.
However, Microsoft will disable the access via IMAP on october 2022. This means IMAP won’t work for that specific use-case anymore.
Does somebody know a way to monitor this without IMAP? Microsoft says that they will rely on so called “modern auth” (authentification against Azure AD via token). But I am not sure which Checkmk-version is needed for that, as my Checkmk-site runs on version 1.2.8b9 (Enterprise).
Yes I have a mail-address where its only purpose is the check.
When the BasicAuth is enabled for that specific address within ExO, do I have to adjust the check-parameters? “Mail receiving” is set on IMAP, and for “Authentication” I already have set username and password for the current check.
There is a workaround to opt-out for the rest of the year. Microsoft will deactivate BasicAuth in January 2023!
Till then the Mail Loop Check either needs to get Modern Auth implemented or a new End2End Check just for ExO.
Here you can read about the workaround and all the other info:
MS has begun the final shutdown phase and several tenants of ours cannot be monitored any longer with the existing check. Is there any work definitely planned to be done, and what’s the ETA? At the moment there is no way to monitor O365 mail delivery with Checkmk.
