Snow Leopard has introduced new sync issues with Entourage Calendar events. Let us know if these options help or if you have found a solution that you would like to share. Entourage-to-iCal time zone synchronization problems
Snow Leopard users are experiencing compatibility problem between iCal and Entourage. When syncing with iCal the calendar times will change to be off by a number of hours (depending on the time zone) from when they were originally created.
Entourage and ICal Calendar don’t sync anymore after upgrade to Snow Leopard
After upgrading to Snow Leopard, Entourage 2008 and iCal calendar events stopped syncing. Contacts and notes are OK, but calendar events just sync one way iCal > Entourage 2008.
Options to fix
Users with incorrect times will need to do both fixes. Fix for time zone issues:
- If you are using Entourage 2004, you might have to update to Entourage 2008 to resolve the time zone issue.
- If you are using Entourage 2008, verify that you are updated to 12.2.1
- Enabled time zones in iCal (iCal>Preferences>Advanced)
In iCal preferences, there is a check box for “turn on time zone support.” If you leave it unchecked, iCal will automatically adjust to your current time zone and move the events forward/back by the appropriate number of hours. If you check “turn on time zone support” a drop-down menu will appear at the upper right of the iCal page allowing you to select the time zone you wish to view. In this mode, iCal does not automatically move the events unless you select a new time zone manually.
Fix for sync and time zone issues:
- Deleting the following Preferences (quit iCal and Entourage before deleting):
- User>Library>Calenders>Calender Cache
- Re-start your computer
- Re-start iCal. It will tell you that it is rebuilding the cache.
- Re-start Entourage
Note: Cache files are temporary receptacles for data that help OS X and its applications work faster. Occasionally caches become corrupted, impacting the performance and stability of your Mac. Deleting caches won’t hurt anything.
Dealing with duplicates
Some users have found that selecting only one item at a time to sync in Entourage Sync Services preferences has helped with duplicates.
If you do get dupes, clean them up with one of the remove duplicate scripts then give every event and contact a category even if it’s a generic category like “current”. All duplicates will have the category “none” assigned. Sorting by “none” you can easily delete all dupes if it happens again. Scripts to remove duplicates If you aren’t familiar with using scripts, see Using AppleScripts with Entourage.
Backups are critical
I suggest you backup your calendar events and contacts as individual items in case you need to restore after a bad sync.
- Open Entourage
- Under File in the menu bar, select Export
- Select Items to an Entourage Archive
- Select All items
- Backup your Contacts and Calendar events separately
