MobileMe: Troubleshooting "inconsistency" alerts when syncing data
Symptoms
With MobileMe sync, you may encounter two alerts about inconsistent sync data. The exact text of the alerts will vary depending on what data type is affected and what you are syncing, but in general, the messages state:
- Inconsistencies in your sync information for Contacts/Calendars/etc were detected and have been repaired. The next sync for MobileMe may take longer than usual.
- Contacts/Calendars could not be synced due to inconsistent data. Confirm that your computer's data is valid, then reset Contacts/Calendars/etc on MobileMe in System Preferences
This article discusses how to troubleshoot both of these types of alerts when syncing with MobileMe.
Products Affected
MobileMe Sync
Resolution
"Inconsistencies... were detected and have been repaired"
If you receive this alert, first try syncing again. The sync may take longer than usual, but if it completes successfully, the issue should be resolved. If you continue to receive this alert, use the steps below.
Data "could not be synced due to inconsistent data"
- Confirm that the data inconsistencies are not due to an "Invalid Change Log jump table size" alert. See this article.
- On the computer that has the most up-to-date information for the data class mentioned in the alert, manually enter any recent changes you may have made on your iPhone, iPod touch, or MobileMe website--otherwise these will be lost when completing the rest of these steps.
- On the computer that has the most up-to-date information, reset your sync data on MobileMe. You only need to do this for the data class mentioned in the alert message. If you are syncing more than one computer with MobileMe, the other computers will present you with an alert the next time you sync that your data on MobileMe has been reset.
- If resetting the sync data on MobileMe does not resolve the issue, you may need to reset the SyncServices folder on each computer that is syncing with MobileMe, and then repeat step 3 again.
To reset SyncServices:- Click here for Mac OS X 10.5.4 or later
- Click here for Mac OS X 10.4.11
- For Microsoft Windows
- Open iTunes
- Choose Preferences from the Edit menu.
- Click the Syncing tab.
- Click the Reset Sync History button.
If you continue to receive data inconsistency alerts after following these steps, contact MobileMe support.
