    Outlook export process…

Click the File tab.

Click Options.

Click Advanced.

Under Export, click Export.

Click Export to a file, and then click Next.

Click Outlook Data File (.pst), and then click Next.

Select the account — a top level folder — that you want to export. This enables exporting all mail, calendar, contacts, tasks, and notes if available for that account.

NOTE Only information for one account can be exported information at a time.

Make sure that the Include subfolders check box is selected.

Click Next.

Click Browse to select where you want to save the Outlook Data File (.pst) and to enter a file name. Click OK to continue.

NOTE If you have previously used the export feature, the previous folder location and file name appear. If you do not change the name, it will overwrite the old file.

If you are exporting to an existing Outlook Data File (.pst), under Options, specify what to do when exporting items that already exist in the file.

Click Finish.

The export begins immediately unless a new Outlook Data File (.pst) is created or the export is to an existing file that is password protected.

If you are creating a new Outlook Data File (.pst), an optional password can help protect the file. When the Create Outlook Data File dialog box appears, enter the password in the Password and Verify Password boxes, and then click OK. In the Outlook Data File Password dialog box, enter the password, and then click OK.

If you are exporting to an existing Outlook Data File (.pst) that is password protected, in the Outlook Data File Password dialog box, enter the password, and then click OK.

If you want to export items for multiple accounts, repeat these steps for each account.


    Outlook import process……

Click File > Open & Export > Import/Export.

Choose Import from another program or file, and then click Next.

Choose Outlook Data File (.pst) and click Next.

Browse to the .pst file you want to import.

Under Options, choose how you want to deal with duplicates

Click Next.

If a password was assigned to the Outlook Data File (.pst), enter the password, and then click OK.

Set the options for importing items. The default settings usually don’t need to be changed.

Click Finish.

Now depending on the rules set fourth, data issues, size of the file, etc, you should now have everything restored to your office 365 email account. We hope this helps you complete your migration.
