Title: MSL Office 365 Connection Issues
Post by: process134 on March 18, 2022, 08:21:17 PM

Hi,

I have an MSL server 10.5.20.0 where I have set the SMTP server to Office 365.

The customer reports most of their voicemails take between 30-60 minutes from the time of message left on MiVB embedded voicemail to delivered in email.

The SMTP-Auth-Proxy log has hundreds of entries every day stating "No SMTP connection to server smtp.office365.com on port 587"

The MSL server is in server-gateway mode directly connected to the internet.

Does anybody have any suggestions?

Worked around this issue by removing Office365 settings from the server. MSL can forward emails directly without using an upstream server if you leave the SMTP server address blank.

Patched for the DDOS AWV issue?

The server is not running AWV, only MBG so no patch required.

If it was a TLS problem I would expect it not to work at all. The behavior was intermittent.

All emails were eventually sent out (some took 1 minute, some took 2 hours).
