I’m using PDS Zimbra to PST Converter, but the conversion fails with errors. How can I fix this?"

Common Errors & Solutions
1. "Failed to Load Zimbra TGZ File"
✅ Solution:

Ensure the TGZ file is not corrupted (try opening it with 7-Zip).

If exported from Zimbra Webmail, re-download the backup.

Use "Repair Mode" (if available in PDS software).

1. "Outlook PST Creation Failed" ✅ Solution:

Close Outlook before conversion.

Check disk space (PST files need 2x the original TGZ size).

Try saving the PST to a different drive (avoid long file paths).

1. "Partial Conversion" (Missing Emails/Attachments) ✅ Solution:

Update PDS software to the latest version.

Disable antivirus temporarily (may block file access).

Split large TGZ files into smaller chunks.

1. "Authentication Error" (For Zimbra Webmail) ✅ Solution:

Verify Zimbra login credentials.

Enable IMAP access in Zimbra admin settings.

Use App Password if 2FA is enabled.

1. "Unsupported Zimbra Version" ✅ Solution:

Check if your Zimbra version is compatible with PDS (refer to their docs).

Export to Intermediate Format (e.g., EML) first, then convert to PST.

Advanced Troubleshooting
🔹 Check Logs: PDS software usually generates error logs (look for error.log in the install folder).
🔹 Contact Support: Share the log file with PDS Technical Support for faster resolution.
🔹 Alternative Tools: If unresolved, try SysTools or Stellar Zimbra Converter as a temporary fix.

Preventive Tips for Smooth Conversion
✔ Backup Zimbra Data before conversion.
✔ Use a Stable Internet Connection for webmail migrations.
✔ Run PDS Software as Administrator (right-click > Run as Admin).
