Hello all,
We have MS sql database which regularly sends the mails to internal office 365 users.
From last two weeks its not working and we have not changed anything from server side.
below are the settings.

when i sent the test mail with above settings we are facing issues and below is the error.

We have checked windows firewall and port 587 allowed in outbound rules.
We have checked with network team and they have allowed in firewall port 587.
But when i tried telnet to smtp.office365.com 587 from SQL DB machine , below is the result

Even we have allowed in windows and network firewall still we are unable to telnet smtp.office365.com 587.
turned off windows firewall
allowed any ports in network firewall.
Uninstalled Mcafee antivirus from machine totally
still same issue ??
We are out of ideas tried everything we thought but still we are unable to understand the issue.
Please help.
Regards,
Ram
