These warnings does not look relevant, and the syncroton log looks normal. Could you provide imap_debug log? Do you see more requests from the client in http access/error log? I didn't try WindowsMail, but it looks like it just stopped after synchronizing folders hierarchy.

I've tried to enable imap_debug, tail it when I perform update from the client, but nothing is printing.

This is the access apache log when I perform client update.

Could it be the user has not yet logged in to webmail before attempting to use ActiveSync? Should be resolved in the latest round of updates.

Thanks for your reply. I've just checked and the issue persist. I've tried with my user and I can confirm I logged first in webmail before adding exchange account.

In the web client, what does Settings > ActiveSync show, and/or what does it show for the "device" or "application" listed?

There is nothing...

There are currently no devices registered.
In order to register a device, please connect it to the server first, using instructions from this page. Afterwards the device should become available for configuration here.

I installed Win10 (User-Agent: MSFT-WIN-3/10.0.17763) and it works for me. I see some problem when the folders limit is set, but this is not default. Check in config.inc.php if you have config['activesync_max_folders'] = 5;. If so, bump the number to 10.

I was testing Kolab on CentOS, so it might be also some other (e.g. PHP7-related) issue.
