Hello,

I'm trying to connect my DNN instance's SMTP server settings to Office365.

SMTP Server: smtp.office365.com:587
Requires SSL: Checked
Username: Email Address
Password: Password for the Account

Using those settings i'm always getting the following error:

InnerMessage:The client and server cannot communicate, because they do not possess a common algorithm

I tried leaving the smtp server without :587 and without SSL checked but none of the varieties work. I triple checked the username/password they are correct.

Could it be something to do with DNN and TLS?
