1. Copy it to some other place and see if you can import from it via File>Import.
2. Find a repair tool from http://www.google.com/search?hl=en&q=outlook+express+repair+dbx
3. Back to your last good backup.
Help! Last night I looged onto my OE6 and clicked on the Inbox folder. It said there was insufficient memory or discspace. The Inbox was very large ( I know I should file better! ).
When I tried again this morning the Inbox showed there were no emails in that folder. A few emails were downloaded automatically when I connected to my ISP, Wanadoo and these are the only ones that show in the Inbox. However if I look at the size of the Inbox.dbx file it is still huge.
Any ideas re how to recover the old emails ( and easily if possible ).
Note: I did try the trick to set up a new dummy folder e.g. xxx and then delete in and rename the Inbox.dbx file but this still shows as empty.
