Sony Xperia Z3 with Office 365…Contacts & Calendar Don’t Sync

If you've recently picked up a new Sony Xperia Z3 (or if you have a Z3 Compact, Z2x or maybe even the much older Zx that have been updated) and your Exchange ActiveSync account is not syncing your Calendar or Contacts to the phone, here is how to make it happen: 

  1. If you've already added your Office 365 mail account on your Sony Xperia Z3 using "Exchange ActiveSync" as the type, it should show up as "Mail" - you can go ahead and delete this account
  2. Once deleted, create a new Account, select Exchange ActiveSync and enter your details
  3. Instead of selecting Automatic Configuration, select Manual, and specify the following: 
    1. Username =
    2. Servername =
  4. This time, it should detect the correct settings from O365 and provide you with a screen that now has not only Email, but Contacts, Calendar and Tasks with check boxes for syncing
  5. Once complete, you should now see your Office 365 Email, Contacts, Calendar and Tasks show up on your phone in a couple of minutes!
I hope this helps some of you new Xperia Z3 users! Now I'll enjoy my Xperia Z3 running Office 365 and OneDrive while I await the release of the Lumia 1020 successor...but until then...

    I held with Sony for 2 hours and they were going to charge me to send the phone back.  I finally found your notes while I was waiting and fixed it myself.  THANK YOU!

    Super helpful, thank you!! Though, I'm now getting a message that I am required to update security settings to give device administrator remote control of security features… not sure I like the idea that my phone can be shut down any time. Can you advise if I have to activate? Thanks in advance.

    That is a standard device "policy" warning for the feature of being able to lock/wipe your device from the webmail interface, or if your O365 is with a company, for them to either do that…or do even more (depending on how much/little they want to control your device…such as a full wipe). If it's just a personal O365, just hit OK and nothing will happen.

    Thanks this has been a saviour, one thing I have noticed is when a new contact is added to O365 it is not syncing to the phone, do you know of a reason why this would be the case?
