Hello,

I have an issue when using an O365 account and sending emails from an application.

The application has been suitable to use tls/starttls, port 587, ect.

When entering an email account and password, the following message occurs:

"535: 5.7.3 Authentication unsuccessful"

I would like to understand, what are the mininal features of an O365 account so that it can be used from another application.

I have performed different tests, which allow me to indicate that the account is Ok.

Thank you.

    Yeah the whole thing has been a game of hot potato for me before figuring this out.  Please mark the original post as the accepted solution if this solved the problem for you.  Good luck! :-)

    Thanks for the insight!

    Will try to do this tomorrow and let you guys know if it worked out for me.

    Godaddy should talk to their Outlook 365 provider and tell them to enable SMTP per default instead of all this hasle...

    Cheers.

    Hi Maria,

    Yes, you can run this from your machine in an elevated PowerShell.  I don't know why this dumb wysiwyg editor keeps changing everything I put in but here's a screenshot that might help.  The fact that it's connecting to "-ConnectionUri https://outlook.office365.com/powershell-liveid/" is why it should work remotely.  Hope this makes sense.

    Since this account was already fixed it just throws errors after this point but the commands above should work.

    Here's the script in plain text:

    Hey Jarrid,

    Thank you for the insight!

    Can you please clarify this method for us dummies?

    Should I run powershell on my own PC?

    Or am I missing something?

    Godaddy support is a pain in the ***... No help at all from them.

    They are telling me that they did enable the SMTP but still I can't authenticate.
