Open or create the PST you want to merge everything into. Then open the
first PST you want data from using the File menu Open Outlook Data File
and drag/drop the data you want into the main PST's folders. Close the old
PST by right clicking on the root of the folders and choosing Close.
Continue this process until you've merged all the data you want.

Hi,

Environment: Outlook 2003 with Exchange 2003

My firm sends and receive lot of emails daily, so we told the user to
archive their emails into PST files.

But some of them have created several differents files like : archive
april, archive march, archive july...

Now they are lost. I would like to keep it simple and merge all these
files so they will only have one archive.

How can I merge PST files ?
