I don't know why. But all of a sudden, the emails I have through GoDaddy (which is Office365) stopped working. The settings haven't changed, and they're congruent with what the sync settings are when I open the email account in Outlook online.

IMAP, outlook.office365.com, Port 993, SSL/TLS, Normal Password smtp.office365.com, Port 587, STARTTLS, Normal Password

When I try to send an email I get the message:

"Login to server smtp.office365.com with username jason@ectpedicab.com failed."

It asks to retry or enter a new password. But the password is correct, and this message keeps coming back.

When I hit cancel, I get this message:

"Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.office365.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'."

I'm at my wits' end. This has all worked just fine for literally years. I don't know what the problem is.

HALP!

Have you checked with godaddy if SMTP mail sending is enabled? Microsoft have begun disabling it as a marketing ploy (I assume to sell outlook) and I would be expecting godaddy to be complicit with they sales approach.

If it is disabled you will need the owl addon to send mail.
