Some customers still see problem with Entourage's Sync Service after upgrading to SP1. For example, they see frequent crashes in Entourage's sync service and constantly see conflicts for the same set of contacts and events in the sync alert dialog although they have resolved the conflicts previously.
Solution: Reset sync service in Entourage and the sync service in the OS. Until you clean up your data stored in the truth (a special database that stores sync information on a Mac), you will continuously sync bad data and duplicates over and over.
For this cleanup process, I recommend these steps;
- Turn Off Sync Services for all your apps
- Clean up duplicates in each or skip to #4
- Turn On Sync Services
- Clean up duplicates again in the one source that will be your primary source
- Follow the steps below to reset Sync Services (this will erase data)
Note: Always backup before deleting data!
Cleaning up Duplicates
- To delete Entourage duplicates, use one of the delete duplicate scripts found here.
- Delete iCal duplicate appointments
- Remove duplicated field data in iCal and Address Book
- Use the Menu command in Apple's Address Book: Card --> Look for Duplicates
Reset sync services and start fresh (Warning this erases data!!!)
- Turn OFF all sync services in Entourage preferences
- Quit ALL Office applications (including Daemon - How to quit daemon)
- Quit Safari, Address Book & iCal and all applications synching through .Mac (Transmit, Yojimbo...)
- Use Activity Monitor to quit Sync Services
- Delete the contents of ~/Library/Application Support/SyncServices/
- Optionally: if you want to replace all data in the system Address book and iCal with Entourage data, delete all iCal & Address Book Data Files:
- ~/Application Support/iCal/*~/Application Support/AddressBook/*
- ~/Library/Caches/com.apple.iCal/*
- ~/Library/Caches/com.apple.AddressBook/*
- Open the .Mac System preferences and make sure .Mac synching is enabled
- Restart all applications that sync to .Mac (Safari, Address Book, iCal, etc.... and Entourage).
- Turn ON Sync Services in Entourage preferences.
Note: Currently syncing with .Mac has problems. You might not want to sync to .Mac at this time.
REPLACE, REPLACE, MERGE?
There's a dialog that pops-up in Entourage when you turn on synching of a calendar or address book that asks something like: "You have enabled Sync Services for a folder, do you want to?"
Replace Entourage items with Sync Services items
Replace Sync Services items with Entourage items
Merge Entourage items with Sync Services items
If you have selected Entourage as your primary source, you will want to select "Replace Sync Services items with Entourage items"
The "Replace Entourage items" option will delete all items in Entourage and override them with the contents of the Sync Services truth. You'd want to do this if you haven't used Entourage in a while or you consider your cell phone's address book the primary "rule" for your contacts.
The "Replace Sync Services" option makes Entourage the short-term rule. All contents within your truth will be deleted and replaced with Entourage items. In this case, all contacts in your Address Book app would be deleted and then replaced with those from the address book selected in Entourage.
The "Merge" option is normally the safest option. Nothing gets deleted. Items in the Sync Services truth go into Entourage and items within Entourage go into the Sync Services truth. Because this can be a bit messy, causing duplication, or unwanted items this is not an option we want to use for this process.
After selecting one of these options, all changes in anything that talks to the truth will be synchronized to any application that listens.

I've done all of the above 4 times now. I still can't get sync services to put my Entourage calendar items in iCal.
Which of course means I have an empty calendar on my iPhone....which means I have a worthless phone and will have to switch back to a BB until July 11th.
Seriously, I can't think of what the issue is... the sync with Entourage 08 has worked for months.
Try testing in a new User. Go to System Preferences --> Create a New User in Accounts. Switch to the New User by logging out/in or use Fast User Switching. You will need to drag your Microsoft User Data folder to Shared so you can drag it to the new Documents folder. (it copies so you data is safe... just drag it back from Shared when finished)
Turn on Sync Services and see if it syncs with iCal in the new User.
i'm using Entourage 2004 to connect to an Exchange server. For some reason calendar and task information is not being synchronized between the local information and the server. I can't see the information if I access Exchange using Web Access, and changes made there don't show up in Entourage
This type of question is not related to Entourage 2008 SP1 and is best asked on the Entourage newsgroup.
How to subscribe to the MSFT newsgroups
Be sure to include the version of Entourage plus updates, your OS, type of machine, server software and what you have tried. Make a subject with Exchange in the first part so it gets noticed by the Exchange experts.
See you on the newsgroup!
I have now tried this fix, four full times. I have set a new user and everything works fine. The Entourage/ICal sync has worked flawlessly until 12.1.0. and OSX 10.5.3. Now contacts work great but nothing else. Had hoped, 12.1.1 would fix the problem. Repeated the steps and >>>Nothing.
I use my calendar a lot....Project managemnt suff which I love in Entourage. Can't someone get this problem fixed?
Since Entourage uses Apple's Sync Services, the fix is probably going to come from an Apple update. Maybe the MobileMe release will be the trick.
Yeah, I'm back. New user trick worked for about a day. Get this though.... I have three options to use with Entourage's sync services in the calendar section.
Local Calendar
Calendar1 - Exchange Server
Calendar - Exchange Server
The problem is, I ONLY have CALENDAR1. Same with my contacts, folder is Contacts1. For some reason if I select Calendar1 I get an empty iCal. If I select Calendar, aka no 1, that should be empty...that populates iCal.... ONCE. No updates are synced. ??? What gives. Perhaps it's something in the way it reads the folder from exchange and if it's just a slightly different folder name... all bets are off. BUT that should break my Contact sync too...but it doesn't.
Sigh....
Let me run this past one of the Exchange folks. I'll get back.
I sent you a message off list. Please check for it.
Of course, the easier solution would be to actually either hire programmers that know what they are doing, or to provide proper QC during the production process.
Since this fails during the initial planning phases ("planning? What's that?"), combined with a group of programmers wholly unfamiliar with proper Mac design practices and framework usage, none of this is any surprise.
Not that it isn't par for the course for the disappointment that is Entourage 2008.
From your other similar comment on another post, I can tell that you are not a happy user. As I advised in the other comment, it's best to send your comments to Microsoft where it might actually do some good.

I've got the same Calendar1, Contacts1, Drafts1, issue.
Only in Entourage 08 though, in a hosted virtual desktop I have Outlook 07 pointed out the same account, in that folder list everything is named correctly (Calendar, Contacts, ect).
I've completely removed my exchange account, removed the identies and rebuilt them... STILL calendar1, ect...ect.
This also effects my iPhone b/c sometimes appointments make it to my iPhone, other times they don't. I'm guess it depends on what email client I use to add the appointment, Entourage or Outlook 07.
