I have two separate from two different computers. Is it possible to easily
combine the two into a single one?
Yes, easily. Let's assume you have Outlook configured on one PC and using one
PST. Place the second PST in, say, My Documents on that same PC and open it
in Outlook with FIle>Open>Outlook Data File. This will open a second set of
folders and you can simply use them that way or you can open each of those
folders, select all the items with Ctrl-A, and click Edit>Copy to Folder,
specifying the corresponding folder in the default PST as the destination. If
the folder in the second PST is not one of the default folders, you can just
copy the folder itself to the first PST without having to open it. For the
Calendar you you'll need to choose a table view like By Category before Ctrl-A
will select all items.
