FMS and Office 365

[Bankesy]

Good afternoon,

 

Really sorry that this is like the third time I'm posting this but really struggling and ESS are just guessing their way through troubleshooting and blaming Microsoft or my internal setup.

 

Has anybody out there got FMS working with 365 please?

 

Thanks

What's not working?

So at at first it was an LGfL firewall issue, couldn't TNC from the Finance PC to smtp.office365.com on port 587 but got that sorted.

 

Within FMS itself, if I enter the connection details for Office 365 and my 365 username\password it works but doesn't work with any other account seemingly. I have no idea what could be different about my account compared to any others.

 

ESS have said I need to enable MFA and set an app password on the account I am trying to use, done that but still no joy.

 

Properly lost on this one.

Where in FMS are you entering a MS username/password? For what reason?

I've had FMS running with Office 365 for years.

 

I have a handful of devices on static DHCP leases that I group and send out of my firewall on 1 of my external IP's.

 

I then whitelist that IP in office 365 as a SMTP relay and voula!

 

On Monday I can dive in and double check but pretty sure that's what I have setup.

I fixed it, the account needed adding as an exclusion to a conditional access policy that blocks legacy authentication.

 

As I had already enabled MFA on the account at the request of ESS I then had to enforce MFA in order to setup an app password, now it works in FMS using the e-mail and app password instead of the Office 365 password.
