Problem with sending e-mails by EMC DPA - tls

Hello,

I have a problem with DPA.

when DPA tries to send reports, he gets the following message: Last failure details: Subject: Backup Report Report name: Backup All Clients Failure message: 421 4.7.66 TLS 1.0 and 1.1 are not supported. Please upgrade / update your client to support TLS 1.2. Visit https://aka.ms/smtp_auth_tls. [AS9P251CA0006.EURP251.PROD.OUTLOOK.COM] DPA is set to TLS 1.2

The question is what do I have to change to make it work, I note that a few months ago there was no problem.

I use an office 365 account, when I tried to change, for example, to gmail, dpa could not connect to the smtp server at all
