Hotmail ActiveSync Quirk with Android – Leave the Backslash Alone!

As you may know, I have started to use a Samsung Galaxy S instead of an iPhone and have been going through the process of settings things up and moving across my content. When I got around to setting up my Hotmail accounts I wanted to use the newly available Exchange ActiveSync interface.

What I found was that despite putting in the settings I believed to be correct it just didn’t seem to work properly. I was fairly sure I put in my e-mail address and password correctly for my Hotmail account as well as the server address of “”.  I even deleted and recreated the Hotmail account to no avail.

Then I realised something.

When setting up an Exchange account in Android, it precedes the provided username with a backslash (i.e. “\” for those who get confused). Previously, I had deleted this as I thought this was a mistake but on my final attempt I left the backslash and put in my e-mail address after it and tried again.

Eureka – it worked!

So if you are facing a problem similar to the issue I faced then make sure you leave the backslash – it will make all the difference!

    I have the same problem still. It loads the folders and old mail OK and will pick up new mail if I put things in my folders, but will not pick up new mail in the inbox. Tesco say I have to use pop3, which does work in it’s boring old fashion.
    The set up or modify account process in the email app won’t let me access domain name to remove backslash.
    Please help!

  1. Hi John. You actually need to leave the backslash there so as to signify a null domain as removing the backslash will cause problems.

    What device are you using?

    I’m using the Galaxy S 91000. With the backslash it syncs contacts OK, but will sync only added email folders, not the inbox.

    1. Apologies in the delay in getting back to you. My wife and I were returning from Japan to Australia after the earthquakes.

      Do you know what ROM you are using? It might be possible that you are using an older ROM with an older client that is displaying this problem?
