The send file of 19Gb sounds extreme to me. Especially if the global store was only 800mb Have you undertaken the normal checks in the operating system to verify the validity of the file image on disk.

The global index is used only for searches and is notorious to retaining pointers to things that have been moved or deleted. So if mail is missing for the actual folders in the program, your issue is not the global database.

IMAP mail accounts are really only ever a local cache of the server content. I have seen a lot of folk close their mail accounts because they have local copies which simply disappear once the mail server account is no longer available to provide a canonical copy of the mail. So seriously you need to provide more information here as well as check the veracity of the file system using something like chkdsk.

It's POP3, it does sound extreme to me too, there is multiple email files missing emails. I did not do compact because I fear it will lose it permanently. when I copied the profile to safe location before I started working on it, the sent failed to copy but the others copied ok, but still missing emails. I tried the repair and it got worse I now see less emails. but the files are still large. 5 gb on the inbox, there are attachments that may attribute to file size. The client had 9 years with 3 email in this profile and never sorted into sub folders so everything was in 'Inbox' is there a software to inspect the file with to see what is in that file? from what I understand the global store is just an index and when I deleted that it gets rebuilt and that is when I no longer can see a few years worth of emails. and can't get that back because the global database I was not able to backup either, but have the inbox file, which is still 5gb. can't explain why multiple email inboxes and sent was effected.

"Have you undertaken the normal checks in the operating system to verify the validity of the file image on disk." it is Windows 7, what normal checks? like a hard drive error scan?
