Exchange Online & Android

The other day at work I was asked if you can connect Android phones to Exchange Online…so I went off to investigate.

Microsoft’s page gives a list of devices and supported OS’s:


I’ve got the HTC Hero and so does the person who asked, so that’s the route my investigation took, I opened up the “Mail” section on my phone and went to work.

The auto-detect feature doesn’t work with Exchange Online (or so it seems) so it’s on to manual setup, which asks for:

  • Email Address
  • Server Name
  • Domain
  • Username (Same as the email address)
  • Password

Apart from a couple, they’re all pretty self explanatory but there’s one that could trip you up:

Server Name:

There are 3 different server URLs depending on location:


but it just wasn’t working for  me, so I called Microsoft BPOS support. After a bit of a false start, they were very helpful and gave me a call to work through the issues.

I navigated to OWA through my browser ( couldn’t log in. I then found it was resolving itself to the “red001…” address, which clearly wasn’t right as I’m in the UK, so I cleared all my bookies, cache etc and went back to the setup screen.

I tried again and still no luck, but then I tried one last thing…entering the server URL without the “https://” and the start. To be honest, I’m not sure why I tried that (although I’m equally sure that someone more techie than me would have tried that first!) but it worked! Entering simply “” worked a charm and BOOM, I could see my emails on my Android device. A quick check revealed that the calendar and contacts were syncing too…brilliant 🙂

I hope that helps anyone wondering if this can be done and/or having trouble getting it working 🙂

  1. Hi,

    I’m pretty sure the domain value just needs to be your BPOS domain but I can’t actually remember! I will confirm and let you know 🙂


  2. Nice piece about Microsoft Exchange Online. However, it’s a pity that Android Exchange support requires third party apps like Touchdown to fully work

  3. One other note – for K9 mail on Android, you have to select “always use TLS” under authentication, otherwise it will never connect. The docs all say SSL.

  4. Thanks man! No idea how long that would have taken me to figure out.

    Here’s a tip if you’re trying to figure out which subdomain to use (red001, red002, etc): goto and login to webmail. You’ll be redirected to the correct subdomain, and you can copy and paste it into android.

    FWIW, mine was

  5. You really make it appear so easy together with your presentation but I find this matter to be really something that I believe I’d by no means understand. It seems too complex and very wide for me. I’m taking
    a look forward in your subsequent post, I will attempt to get the dangle of it!

  6. Hey there! I’ve been following your web site for a long time now and finally got the courage to go ahead and give you a shout out from Humble Tx! Just wanted to tell you keep up the great work!

  7. I do not even understand how I stopped up here, however I believed this submit used to be great.
    I do not realize who you are however certainly you are going to a famous blogger when you aren’t already. Cheers!

  8. I have been browsing online more than 3 hours today, yet I never found
    any interesting article like yours. It is pretty worth enough
    for me. In my view, if all website owners and bloggers made good content as you did, the net will be much more
    useful than ever before.

  9. I believe everything said was actually very logical.
    However, think about this, suppose you were to create a awesome post title?
    I ain’t saying your content is not solid, however what if you added a title that grabbed people’s attention?
    I mean Exchange Online & Android | Software Ruminations is
    a little boring. You could peek at Yahoo’s home page and note how they create article titles to get viewers to click. You might add a video or a related pic or two to grab readers excited about everything’ve
    got to say. In my opinion, it could make your posts a little livelier.
