We use GroupWise Mobility Service 2014 R2 and a only iOS devices.
Sometimes we've got some issues with the synchronization of a calendar and inbox. When i then re-initialize the user he/she lost al her email in the cabinet on the device and then it doesn't synchronized all of the email in the cabinet but only the email wich will put from then in de folder/cabinet.
So all the "old" email wich was in the cabinet isn't sync anymore.
Is this a setting or a limitation of GMS?
