Capsule Workspace - Users get randomly signed off

[Christoph]

Hello,

has anyone an idea why Capsule Workspace users get randomly (between 1 hour to a few days - timeout is a few weeks) signed off and have to reauth with cert and password.

In the logs I get:

User has logged out of the application
The user does not have other devices logged in. User will be un-registered from the Exchange server.
User has signed off - Log out event.

What does this even mean. These are all iOS devices. These logouts happen at random times, sometimes in the night. Often the user is not using the device at that time.

Cheers Christoph
