Was the pst file created in Outlook 2007? Can you open it in outlook?  Do
you still have the psts that were used to create this larger file?

I have a very large OUTLOOK 2007 PST file after combining several files,
it is over 4GB in size (I have had big ones before and been able to sort
them out).

I keep getting "message interface" errors.

I can't run archive, compact, open another PST file, export to another
PST file.

I have run SCANPST but still can't fix the file.

I can read messages and I can send messages.

I thought of starting a new PST file and open this one at the same time.

Any suggestions of any other ways or repairing the file?

It is not a very issue. Inbox repair tool or scanpst.exe is unable to repair
pst file whose size is more than 2GB or 4GB. In this situation, first of all
you need to split the pst file in small size after that try to repair pst
