I have had a few notices in the last couple days via email that tell me a user added a new device.  Low and behold the new device is a Mac and 2 out of the 3 people are using work Mac's (we only have a few of these throughout the company).  The users were prompted to upgrade to Outlook for Mac and once they sign in with their network credentials, I get the notice of a new device being added to MaaS360.  We don't have policies set up for these devices because we don't add laptops/desktops/Macs to MaaS360.  We only use MaaS360 for iPhones, iPads, and Android devices.  Our normal users who use Microsoft Office on Windows laptops sign into Outlook all the time and I don't see notices of this nature in MaaS360.  Per chance, do you know what is causing this to happen?  I'd hate to not get the notices at all, because of the 3 notices I received, one was an employee trying to access their work email from a personal Mac computer, which we don't allow because it's a security risk.  We have no control to remove that account should something happen to that computer or they ever leave the company we can't wipe away the information that would remain on the system.  Is there some way to differentiate between work Macs and home user Macs?  I'm not sure I'm asking the correct questions or even how to relay the exact issue.  Please let me know if I can provide more information to help this make more sense.

Matt,

The managed status says, "Not Enrolled (ActiveSync Managed)".
