Running Office365 Exchange for a corporation, I am unable to enforce any policy on Mac Mail when it's using an active sync connection. It actually does not show up as a device (I even looked at this through PowerShell) and thus no filter/policy can be applied to it and essentially gives the device full access to the account. I consider this a huge security flaw when you're trying to enforce active sync policies. Has anyone seen this issue before?
As a side note: Windows 8 Mail and Windows 7.1 Phone Mail both are incompatible with Office 365 policies that include limiting the amount of past emails or calendar items, and Outlook 2013 seems to be completely incompatible with Office 365 Exchange accounts, regardless of policy.
How can I prevent Mac Mail from connecting via Exchange ActiveSync while still allowing my other devices?
