Morning, my credit union recently switched to Office 365.  We have recently noticed an issue with employees accessing their emails via their mobile devices.  Only a certain group of employees are able to do pre Office 365 conversion.  We have disabled Exchange Active Sync for my account on the Admin site.  Yet I am still able to access Outlook via my phone.  Any ideas?  Thank you all.

If you want to restrict user accessing Mails outside Office network then you can setup Conditional Access with white listing certain IP Range.  You can implement EMS E3/E5 to gain better control how data is accessed and from where its accessed

Thank you for the reply.  I looked at the link and those are the steps to set up a mobile device.  I need a way to prevent workers from accessing Outlook on their mobile devices.

With the new "native sync technology", you need to block it via a different parameter:

 

Set-CASMailbox jane@contoso.com -OutlookMobileEnabled $false
