If there is a problem with your email software, you need to back up
whatever left of your email before attempting any kind of repairs.
- Certain tools (e.g. ScanPst for MS
Outlook) will modify the email database during repairs. If the
repair goes wrong, the situation may become worse than it was before
repairs. You would need to revert to your backups to try another
- Sometimes the email client might damage the once broken
database further upon startup.
Typically, backup is done by just copying several files somewhere to
a secure location. Make sure your system settings are
configured as appropriate, then see the
corresponding email client reference for the location of its message
base files (MS Outlook,
Thunderbird). You need to copy
these files somewhere outside their original location using either
Windows Explorer or your favorite file manager.
