E-mails saved in a .pst file can be used in two ways:
Variant 1) Attach as folder: This option allows you to manage your „old“ emails manually.
Variant 2) Use as import source: All your „old“ data can be imported/transferred to another/new mailbox.
Variant 1: Integrate Outlook PST as a folder:
1. In the top left-hand corner, left-click on the „File“ tab.
2. In the next window, first click on „Open and export“, then select „Open Outlook data file“.
3. In the new „Open Outlook data file“ window, go to the path that you used for your backup. (Here in the example) Go to „C:“ and then to the „Outlook“ folder. Click on the PST file „Backup.pst“, then confirm with OK.
4. If the password prompt appears, please enter the password you have set for the Outlook .pst file. Optionally, you can tick „Save this password in the password list“ so that Outlook saves your password and does not ask for it again.
5. You will now find a new entry „Outlook data file“ or „backup“ in the mailbox/folder list on the left-hand side. After expanding it, you will find your old data there.
Option 2: Import Outlook PST into the mailbox:
1. In the top left-hand corner, left-click on the „File“ tab.
2. In the next window, first click on „Open and Export“, then select „Import/Export“.
3. The import/export wizard appears. Here you select „Import from other programmes or files“. Once this is highlighted in blue, click Next.
4. Select the sub-item „Outlook data file (.pst)“ in the „Import file“ window. Once this is highlighted in blue, click Next.
5. In the new window, click on „Browse“ to select the storage path:
6. In the new „Open Outlook data file“ window, go to the path that you used for your backup. (Here in the example) Go to „C:“ and then to the „Outlook“ folder. Click on the PST file „Backup.pst“, then confirm with OK.
7. The newly selected path with file is now displayed and you can click on „Finish“
8. In the next window you must enter the password for your Outlook .pst file, if set, then confirm with Ok. Optionally, you can tick the box „Save this password in the password list“ so that Outlook saves your password and does not ask for it again
9. Confirm the selection with „Finish“ in the next window
10. You will then be shown the progress of your data import. Please do not click on „Cancel“ until the process is complete. The import time varies depending on the size of the mailbox. Once the process has been completed, all old data will be in the current mailbox.
