Here are the most basic steps to Configure Office365 on your android device.
On your android device, in your mail app, press the menu button and press ,New Account’.
Press “Microsoft Exchange” or “Microsoft Exchange ActivSync” to add your new account.
Enter your fully qualified e-mail name (eg. email@example.com) into the Email box and your password into the password box. Press Next.
The android device will use Office365’s autodiscover feature to fill in the server box. If it doesn’t type in ‘mail.office365.com’. Leave the domain box blank. In the username box type in your email address. Click Next.
You can now customize the items that the android device will synchronize. Unless you’re doing something pretty unique, there is no reason not to synchronize them all. Select how often you wish it to check. and Click Next.
Give the account a name for example ‘Office 365’. Click Finish Setup.
