To compact and back up mail folders

1. Select a mail folder, click the File menu, point to Folder, and then click Compact.

2. To back up the compacted folders, find the files with the extensions .mbx and .idx, and then copy them to a backup folder, floppy disk, or network drive. Each message folder has one message file (.mbx) and one index file (.idx).

Notes

• Some message files might be too large to back up onto a floppy disk.

• If you are using a program other than Outlook Express to send e-mail messages to newsgroups, check your e-mail program's documentation for information about compacting and deleting mail folders.
