Add Novel Groupwise Account via Exchange ActiveSync to Mail I want to add my Novel GroupWise account to my Mac, which is not possible due to the lack of a (reliable and recent) client. The firm I'm working for set a data sync server up for this purpose but that only supports Exchange Active Sync if I am understanding it correctly.

I am assuming this because setting up the account as an exchange account on the iPhone and iPad was no problem but it does not work in mail. 

Does there exist a workaround for this situation? Maybe some daemon that pretends to be an mobile client and fetches everything? I would really like to be able to add the work calendar and emails on my mac. I'm running the latest El Capitan an a Macbook Pro.
OS X only supports Microsoft Exchange, not Exchange ActiveSync. ActiveSync is only supported on iOS/Android  This is why Mail will not connect but your iPhone and iPad will.
