Outlook mobile ask to apply the pasword each logon active sync

We are satisfied with the Kopano web-app, but each time we open the outlook client on a mobile device, it ask for the user credentials.
Same issue happens, on a iPhone, or Android client.
This happens already for a couple months, but can’t find the solution.
Hopefully one off you can tell me how we can solve this issue!
Thanks.

Best never ever use outlook app on android or ios - this app is a Men in the Middle App - your client will never auth to your kopano server directly - it connects to a microsoft server which then auths to your kopano server - so all passwords are stored at microsoft too.

i can not agree with this article where Microsoft has removed this - as i have still customers using this app and they all access the server through ms servers (you can see the ip of the connection on z-push)
