Hi,
we are facing sporadic, non reproducible problems with ActiveSync. Sometimes changes in the appointments (acknowledgements, creation) or contacts (creation) are lost / don't get synchronized.
We are using a cascaded installation of sophos web application firewall and a kemp load balancer and two Exchange 2016 servers. Most of our ActiveSync devices are Apple iPhones and iPads.
Are there any known issues (problems, timeouts, ...) regarding ActiveSync synchronisation?
How can this be best troubleshooted in an environment of several hundred ActiveSync clients?
Thanks
Bernd
