Nagios Support Forum

Hi Everyone,

I'm trying to set up an Email Delivery check (using the built in wizard) to check mail flow from a local SMTP server to an Office 365 mailbox.

The email is delivered ok, but I get an error when the check tries to connect to the Office 365 mailbox.

The command that runs and the error I get are :
I've ran nmap outlook.office365.com 143 and it tells me the port is open, so my Nagios server can see Office365's server ok.
I'm running Nagios XI 5.4.10.

Any suggestions will be appreciated.

It may be open but those aren't the ports it usually uses, see here

also, looks like you are not providing SMTP username and password which may also be required as well as the correct port for that.

From what I recall, Office365 requires you to configure a relay server (within Office365) when connecting via SMTP/IMAP (or really anything other than Outlook or webmail). You should hit that relay server with check_email_delivery rather than the cloud Office365 server if you aren't currently. I could be wrong, my memory is a bit fuzzy.

Thanks Guys - I'll check those things out, and let you know how I get on.

Sounds good! Let us know if you have any more questions.

If not, let us know when we can close this thread.

Tried again, this time with SSL enabled and on Port 993, and it now works.

Thanks for your help!
