It works for me. Since you reference "smtp.office365.com" I assume you are trying option #1 here:
How to set up a multifunction device or application to send email using Microsoft 365 or Office 365. You must use the same email address for sender and user name in the SEPM server email server configuration. This would be the same email address that you use to login to
outlook.com, and same password.
"Send Test Email" sends a test message using those credentials, to the email address configured for the SEPM administrator currently logged in:
Otherwise check error log "scm-ui-
yyyy-mm-dd-hh-mm-ss-mmm.log" in %temp% directory for explanatory errors from the test attempt.

Subject: SMTP.Office365.com and SEPM
I am getting conflicting reports if smtp.office365.com can be used as the Mail Server in SEPM v. 14.2. We do not have a local smtp server. To date, I have not been able to get it to work.
Has anyone been able to get this to work?
Thank you.
