[horde] Outlook loosing connection

[Michael Friebe]

Hello everyone,

since a few days I've encountered a problem with ActiveSync and Outlook 
clients. Every one or two days, Outlook can't connect to the server 
anymore and claims it wouldn't be reachable. But other clients like 
smartphones are still working fine. We updated Horde to the latest 
version, but the issue persists. After removing and re-adding the 
ActiveSync account to Outlook, everything works fine again for a few days.

We haven't changed anything on the server side, the issue started about 
2 days ago. Could it be that a minor Outlook update somehow broke 
compatibility with ActiveSync in the newest Horde version?

Regards,

Michael
