Then do a wireshark trace and find out what is actually happening. I can only go by the fault code you provided, and yes, Office365 can easily block inside a domain and does.

I have put the address in the "allowed" section within Office 365. I have also run a mail trace and I can't see any of the emails coming into Office 365 since we updated the firmware.
Although since changing that we are now getting the error code 016-781.
Thank you for your help.

You had to have changed something on the printer to get 016-781, or someone else did, because that means absolutely no data to the server, meaning the printer never found a connection of any kind to smtp.office365.com, which would not happen due to encryption or protocols, it could only be that the server is put in wrong, or the gateway/subnet/DNS is wrong on the printer.

with a new System there was again the failure, that no mail was send with the office365 smtp server.
But i found the problem:
Check under System/Security -> SSL/TLS Settings, that for "Device Certificate - Client" is the Machine certifikate selected.
On our new system this was not specified, after selecting the certificate of the system, the mail send works with office365 !

Recent experience with a B7035: Kept getting 016-781 server connection error
using smtp.office365.com port 587. It would send once, then seemed to get blocked for 30 minutes.
I was at the point where I was ready to do a Wireshark trace....then a 2nd Level analyst saw that the device was set up (under connectivity) as "Dual Stack"...changed it to ipV4, and turned off ipV6...
This fixed the problem...
