Data import issues

Here's how to troubleshoot problems you might have when using Google Workspace Sync for Microsoft Outlook (GWSMO) to import data to your Google Account.

Try the Log Analyzer

This tool can identify most issues within a few moments of submission. 

• Submit your trace logs (as uncompressed or ZIP files) to the Google Admin Toolbox Log Analyzer.
• For advanced log analysis, submit uncompressed files to Log Analyzer 2.

Importing & migrating issues

Some or all data not importing from old account

• Check you're connected to the web during the migration and not experiencing network connectivity issues.
• Don't import from an OST file. GWSMO supports importing only from a PST file or directly from your Microsoft Exchange account. Learn more
• Import directly using GWSMO and don’t drag files from IMAP folders. GWSMO doesn't support this method as it can cause import issues. If you didn’t import directly from GWSMO, re-create your profile and try to import the data again.

Duplicate contacts & calendar events after import

If you import contact or calendar data multiple times into the same Google Workspace account, you get duplicates. You can manually remove them from your Google Workspace interface (not Outlook). Or, you can follow these steps to reimport that data:

From your Google Workspace interface (not Outlook):

1. Delete all events in your primary calendar.
2. Delete all contacts in your personal contact list.
3. Use GWSMO to reimport your calendar and contacts. To do this, follow the steps in Import your Outlook data later.

Where can I find trace log files?

You can find GWSMO trace log files on your computer here:

• Windows 7 and up—C:\Users\your-user-name\AppData\Local\Google\Google Apps Sync\Tracing\
• Earlier versions of Windows—C:\Documents and Settings\your-user-name\Local Settings\Application Data\Google\Google Apps Sync\Tracing\

Unified single sign-on trace log files are located here: C:\Users\your-user-name\AppData\Local\Google\Identity

"One or more items failed to import" error

You can find details about the unsuccessful import in Outlook's Sync Issues/Local Failures folder. If you get this error, the rest of your data will continue importing.

Certain message classes (read receipts, delivery reports) not imported

GWSMO doesn't migrate certain message classes, including read receipts, delivery reports, and nondelivery reports. For details, go to What's synchronized?

Are there known issues?
