I am using OE 6.0. Today when I opened my OE, my emails in inbox were gone. Inbox.dbx still shows its size 0.99Gb. I have tried a solution of copying all of my emails folder to some other location and then renaming my inbox.dbx to inbox.dbx.old and importing emails from the copied location. This didn't work. Please help me to comeout of this problem.
it sounds like you have a corrupt mailbox in Outlook Express, due to the age of the program it is no longer a supported email client. You can download windows live mail for free from Microsoft, which is the new vewrsion of Outlook Express.
If memory serves, 1GB is the size limit for an Outlook Express .dbx file and it will blow up like this when you reach it. The files often corrupt above 300MB so avoid Outlook Express for business emails. It's just too old. Don't forget also that on older PCs which may have a FAT32 file system, the size limit of any file is 4GB anyway, and Windows Live Mail or the full-blown Outlook still won't be able to take you past this limit, without converting to NTFS.
Hope This Helps,
