Mail notifications with Office365

[exgame]

Hello,
I'm struggling with Office365 and Exchange. I do get this error
mail: cannot send message: Process exited with a non-zero status ssmtp

it works perfect with gmail, config:

[email protected]
mailhub=smtp.gmail.com:587
rewriteDomain=your_local_domain
hostname=your_local_FQDN
UseTLS=Yes
UseSTARTTLS=Yes
AuthUser=Gmail_username
AuthPass=Gmail_password
FromLineOverride=YES

[exgame]

Microsoft365 config

[email protected]
mailhub=smtp.office365.com:587
rewriteDomain=domain.com
hostname=domain.com
UseTLS=yes
UseSTARTTLS=yes
[email protected]
AuthPass=password
FromLineOverride=YES
AuthMethod=LOGIN

I'm using debian jessie 8 with ssmtp

Make sure the users you're using actually have a license and a mailbox, and that you are able to log into them with the same details in Office 365.
