Hi sulliviana, merging PST files into one is very helpful. There are two ways to merge PST files: manually and by using a third-party PST merger. Manually:
- First locate all those PST Files which you like to merge.
- Bring All PST files to one System folder.
- Choose one PST file amongst them which serves as base, into which other PST files get merged.
- Open your chosen PST file in Outlook First
[ Start MS Outlook > File > Open > Outlook Data File…]
- Then Open remaining Personal Folders the same way in Outlook.
[Outlook listed all open PST files in its navigation. If you are unable to view opened Personal folders in navigation then bring navigation to “Folders List” mode (Folder icon at bottom left of navigation).]
- Now expand PST file opened just after your chosen primary and select any folder within it to merge to PST file you opened first.
- Take for instance “Contacts”. Right click on contacts, choose “Move Contacts…” from context menu.
- A Pop-up Window opened showing all PST files you just opened including Personal folder default to Outlook. From there select your first opened PST file and select “Contacts” therein. Select “OK” and you are done merging contacts of two PST files.
