Hi

I have recently managed to set up shared calendars on our system. All users using Kerio Outlook Connector and Outlook. All users have iPhones with Active Sync installed with data being 'pushed' to the phones.

However, it can sometimes take 1-2 hours for appointments entered on calendars in Outlook to appear on anyone's phone. This seems to be particularly so when entries are made or edited via a shared calendar and the entry is made by a 'sharer' rather than the main calendar 'owner'.

Can be very frustrating if appointments are altered whilst you are out of office as this has on occasions led to changed appointment times being missed

Is there a way of speeding up the 'sync rate' from the server to phones?

Well, iPhones are quite bad in working with shared calendars. Nevertheless, it should not take hours to sync the data. I would start with verifying how fast is the synchronisation from Outlook to server (eg. by viewing the calendar in Kerio Connect Client) and then enabling Activesync debug messages in debug log to see when the change is downloaded to clients.
Please note that if the calendar is shared with many users, some users may exclusively lock access to the folder for a very long time (especially if they manipulate data over very slow cellular connection).

OK, got me there! I can see the debug log but how do I "enable ActiveSync debug messages"?

I have 'test' appointments set up throughout this afternoon on Outlook, Kerio Client, shared calendars and on the iphone and some 3-4 hours later, not one of them has sync'd to or from the iphone. I have turned everything down to only 1 sharer on a calendar. Network speed isn't an issue - 20Mb wifi & 4G on the phone. Even closing down all running versions of Outlook to make sure no-one has 'locked' a calendar makes no difference.

If ActiveSync is genuinely "...quite bad..." working with calendars then it is next to pointless having it in the first place. It needs to work reliably or we need to know it doesn't actually work at all!

Right click in the debug log.

I said that "IPhones are quite bad ... with SHARED calendars". Because ActiveSync was not designed for multi-calendar and iOS client sometimes goes crazy (eg. accepting events and putting them to wrong calendar when two shared calendars (of two users) contain the same event).
