Just set that profile to use the same Outlook Data File that the original
profile used:
To use another PST file (such as one from another installation) and set it
to be the default for your current installation of Outlook, you will first
need to know the location and name of the PST file you'd like to use as your
new default. Then use the following directions
- Go to Tools > Options > Mail Setup > Data Files > Add...
- Add the PST you'd like as your new default, then Close > OK to exit the
Options dialog
- Go to Tools > E-mail Accounts > View or change existing e-mail accounts
- Select the PST you just added in the "Deliver New e-mail to the following
location" dropdown (it will most likely appear just below the current
default Personal Folders file) > Finish
- Exit and Restart Outlook
- You can now close the previous default PST (R-click on that pst folder
while in Folder View and select "Close <foldername> Folders"). If you have
any information in your former PST that you'd like to transfer to your new
default PST, you can drag and drop from one to the other before you close
the old one.
