Hi,

Please make sure the antivirus/firewall does not block the connection. Put Backup4all in the exceptions list.

Hello,

I had the same problem with office 365 smtp server on all device and dont have activated antivirus or firewall.

This is chilkatlog where indicate that Failed to establish TLS connection.

Could it be some new office 365 security policy which prevents the use of the SMTP server?

Hi,

Please make sure you selected port 587 and SSL encryption.
If you still have the problem, please send us a screenshot with this page to support[at]backup4all[dot]com:
File->Options->Email, to see how you configured it.

Hi,

We recommend you to re-enter the password for that email account, to make sure it was not changed in the meantime. Do you still have the problem?
