When you connect to Microsoft Exchange Online in Microsoft Office 365 over Microsoft Exchange ActiveSync, your Office 365 email account is not automatically set up on your Google Android device or on your Apple iOS-based device (such as an iPhone or an iPad) through the Autodiscover service. Also, you cannot access your Exchange Online mailbox from your mobile device.
When this problem occurs, you may also receive an error message that resembles the following:
Note This error message can vary depending on the device that you use.
Unable to connect to server
This problem occurs if the mobile device does not fully support certain Exchange ActiveSync protocol requirements for redirection.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
