I have a Mac running Outlook 2011 in a corporate environment with Exchange. Then i have iPad and iPhone devices. Mostly all Office and Outlook applications work fine except the very different functionality in some aspects compared to Windows except calendar syncing.

All my devises are in the same time zone, i have time zone support on as i travel and i have colleagues across the globe.

Often when i create events or meetings they are fine, sync across devices and remain stable. Sometimes, and there seems to be no particular common thread, the sync goes wrong. I will set a meeting between 0900 and 1000, send to the invitees, then for no apparent reason it suddenly changes to 0600-1000 or 0900-1200. The it updates the invitees. 

Recurring meetings seem to be the worst offender, these often stretch from 45 mins to 5-6 hours for no reason. Even more common if i set a recurring meeting or one is sent to me then its changed. It seems to be OK until the change then it goes crazy.

I also get Sync Error message by the dozen, shows as small warning triangle in bottom right and states:

EXAMPLE: Could not synchronize record: 1:1 Weekly  (xxx / xxx) to Exchange server: yyyyy. Error Code: 19758

I have trawled through many forums all say there are issues and many relate different fixes, none have worked for me. I have tried the most common one of changing timezones to one not so problematic (I am based in Israel). I used Turkey, no change.

It is a disaster in a corporate environment as i often have to call to confirm meeting times, if i am running around i get notified an hour late or early, people show up at my office in the same way. Complete mess and i cannot find a solution and I am not going back to Windows.

Suggestions?
