Hi All,

The Cobian Backup cant email the log files with MS O365 SMTP server. I use this settings:
SMTP server: smtp.office365.com
Port: 587

The self test is woking but the Log doesnt arrive. There is an error msg in the log:
2021-12-23 04:31 *** Backup done. Errors: 0. Processed files: 392931. Backed up files: 392931. Total size: 303,40 GB ***

Someone use Office365 SMTP to send log files?

Hi,

Yep, the same happens to me while using Cobian Gravity.
It looks like Microsoft is discontinuing their support for TLS 1 and 1.1.
If you want to keep using them you should configure your exchange online and use another server.

It isn´t so easy to do, for me at least, it requires powershell access.

I was wondering if the new Reflector address this issue, but I only found your message, so I assume it does not. I´m assuming you are using Reflector.

The new one does support 1.2
