In this blog post, I describe in detail how to import bulk
user accounts to Office 365.

Step 1: To begin, log into your Office 365 site using an
Admin account. Next, go to the Office
365 admin center. Expand the Users
section on the Dashboard and select
the Active Usersmenu. See image
below.

Step 2: Click on the Bulk add icon as shown below.

Step 3:  Click on the
Browse button and open to CSV file. If you don’t have a CSV file, you can
download one clicking the Download a
blank CSV hyperlink.

Next, enter information in the CSV file as shown below.

And open to file.

Step 4: Click on Next
button.

If there is no error, the CSV file is ok. However, if there
are errors, you will need to check the CSV file again to make sure that the information
in the CSV file is exact.

Step 5: Click on Next
button again. Configure Sign-in Status
and Select User Location.  Click Next.

Step 6: Enter your email address in the field. All account information
will be sent to this email after users are successfully created. Click Create.

You will get a message that the new users were successfully
created.  The message will include the new user’s information.

Click Close. You
will see all accounts are updated on the Active
Users page.
