Move your old email, calendars, and contacts to Microsoft 365

If you have email, calendar, and contacts that you'd like to move over to your Microsoft 365 Account, follow these steps:

Migrate your email using Outlook

Step 1: Add Gmail account to Outlook and export a .pst file


Steps may be different between the new and classic Outlook for Windows. To determine which version of Outlook you're using, check if there's a File option in the menu (located above the ribbon). If there's no File option, follow the steps for classic Outlook.

If you are using new Outlook:

  1. On the View tab, select View settings.

  2. Select Accounts > Email accounts.

  3. To add an account, select + Add Account, select a suggested account from the dropdown menu or enter a different email address, and select Continue.

  4. If prompted, enter your password for the account and select Done.

If you are using classic Outlook:

  1. Go to Outlook > File > Add account.

  2. Type in your email address, select Connect, and select Done.

    Outlook sign in

  3. Select the account > File > Open & Export > Import/Export.

  4. Select Export to a file > Outlook Data File (.pst) > Next.

    Outlook pst

  5. Make sure to select the email, select Include subfolders, and then select Next.

  6. Select Replace duplicates with items exported, browse and select a location to save the .pst folder, and then select OK.

  7. Select Finish.

Step 2: Import Gmail .pst file to Microsoft 365 account in Outlook

  1. In Outlook, go to File > Open & Export > Import/Export > Import from another program or file > Outlook Data File (.pst) > Next.

  2. Select Replace duplicates with items exported, browse and select a location to save the .pst folder, and then select Open.

  3. Select Import items into the same folder, and then choose your Microsoft 365 account from the list.

  4. Select Finish.

Migrate your Gmail calendar using Outlook

  1. Go to, and log into the account you want to migrate to Microsoft 365.

  2. Pick a calendar to migrate > Settings and sharing > Export calendar.

  3. Save the .zip file wherever you want, right-click the file, and select Extract.

  4. Go to Outlook > File > Open & Export > Import/Export > Open an iCalendar or vCalendar file > Next.

  5. Go to the saved file, select the file, select OK, and then select Open as new or Import.


The Open as new option creates a separate calendar in Outlook, and the Import option pulls all the calendar items into your Outlook calendar.
