outlook.com custom domain email not authenticating?

Currently I use Microsoft’s outlook.com custom domain email system, and two days ago, it stopped working.

My Android phone running K-9 Mail (for email) and Exchange Active sync (for calendar), simply said “authentication error” with K-9 Mail saying incorrect username/password when editing the account as well.

Why all of a sudden did it stop working though?  It’s been working perfect for the whole year.

It turns out that Microsoft has upgraded everyone (or most?) on a custom domain to the new exchange platform, similar to the office 365, with Outlook Web App when you sign in via a web browser (it has “owa” in the address bar, with many other visual differences). BUT, Apparently according to some Microsoft forums, authenticating with your custom email won’t work due to bug. Instead, as a work around, you need to make an outlook.com(.au) alias, wait 24 hours and use that to sign in on your email client.

I already had an outlook.com.au alias, and it worked fine using this. Tested on:

  • IMAP – on K9-Mail
  • Active Sync Exchange on Outlook 2013

Hope fully the email team will fix this, but until then, either use a web browser or create an alias to sign in with, on the your email client. Otherwise, it’s an excellent service.

PS: Don”t like the alias email name in outlook? this page will help to rename it.
