  1. Looks awesome, but doesn't work for me :(

  2. For the server address, copy the "Exchange Client Access server name" from the About area.

    For the exchange proxy setting, still use the "Host name".

    To note, the Exchange Client Access server name is different for all users (from my experience so far). So get your users to log into Office 365 and go to:

    Highlight and press ctrl+c for copying as right click menu won't work.

    Hope this helps anyone else here.

  3. You did it! Thanks for helping me out.


  4. This worked perfectly. THANKS! I wish MS had something as straightforward as this posted...

  5. Wish someone could figure out how to get Macintosh Outlook 2011 to work with Office 365 ...

    1. Did you try the instructions here to connect Outlook for Mac 2011 to Office 365?

    2. if Outlook 2011 doesn't automatically configure the account, use these steps:
      1. Find out Exchange Online server name by signing in as the user to OWA (or using a different method, there are a couple). Let's say it's
      2. in Outlook 2011, enter in the server name area.

      that's it.

  6. works! great info

  7. Thanks mickey.keightley for the updated post, worked great

  8. I am trying to configure two office 365 email accounts in Outlook 2010 using seperate Outlook profiles but the second account does not work and keeps prompting me for username and password during configuration. Is there a way around it??
    I have Outlook profiles manually setup.


  9. Wasted too much time trying to configure manual connection using microsoft KB article.
    Thanks to mickey.keightley for update, finally it works :).

  10. Thanks buddy, this worked great!

    I spent several hours screwing around with auto-configure in Outlook 2010 and Office 365 before I stumbled on to your wonderful blog. Now I'm up and running! :)

  11. I found that it kept prompting my for my credentials when trying to resolve the name. If I finished the setup (without resolving the name) and then just launched Outlook, the credentials took and it worked fine.

  12. Same here - spent hours trying the autoconfigure etc - this is the only thing that worked.

    now how do i get my contacts back!

  13. Thank you very much - your directions worked perfectly!

  14. Worked perfectly! Two days lost trying to connect and now I did it! Thank you!

  15. That's the best settings I have seen this year. I think you can make even Kiosk accounts to work as 'Exchange' by using this settings in Outlook.

    Thank you

  16. Does work well, if 2007 or 2010 - pitty Office365 doesn't support Outlook 2003 :(

  17. Quick question
    If I want to test the trial versions of office 365 and connect desktop outlook2010 to it which trial version should I choose or do both trial versions allow connections from desktop utlook 2010

  18. Thanks!!!!!!

    excelent post! you saved my life!

  19. This may not apply to Exchange 2013 as they have changed to use a "connection point" instead of the "" as server.

  20. I have read your blog it is very helpful for me. I want to say thanks to you. I have bookmark your site for future updates. hotmail mail
