So, before I start telling you the steps to use the bulk import, you must first know about CSV files and how to create an Office 365 supported file. A CSV file is an easy way to transfer a large amount of data between programs. It is a plain-text file that stores database-style information in a particular format. The format requires one record on each line. Commas must separate fields within records. You can use the Bulk add users wizard to upload an existing CSV file, or you can use the provided blank CSV template and edit it in a text editor such as Notepad. The template contains user data column labels under which you enter information about the users you want to import. The wizard also includes a sample CSV file that provides a correctly formatted example containing sample user data. When you create a CSV file, you can enter user data column labels in any language or characters, but the order of the labels, as shown in the sample, is essential for the correct fields to be populated. You can then make entries into the fields, using any language or characters, and save your file in a Unicode or UTF-8 format. The minimum number of rows is two, including the first row of user data column labels (the second row is a user). The maximum number of rows is 251, including the first row of user data column labels. Only the user name and display name are required entries. If you need to import more than 250 users, create multiple CSV files. The user data column labels and maximum character length for each in the sample CSV file are:

User Name (Required): The maximum total length of the user name is 79 characters (including @ symbol) in the format [email protected] The user’s alias cannot exceed 30 characters, and the domain name cannot exceed 48 characters.First Name: 64Last Name: 64Display Name (Required): 256Job Title: 64Department: 64Office Number: 128Office Phone: 64Mobile Phone: 64Fax: 64Address: 1024City: 128State or Province: 128ZIP or Postal Code: 40Country or Region: 128

While making your CSV file for Office 365, you must keep these few things in mind, or else you will get an error:

Suppose you are importing users from different countries or regions. In that case, we recommend creating a separate CSV file for each country or region and performing a bulk import operation for each CSV file. You will indicate the users’ location in the CSV file as part of this import process, and only one location can be selected per bulk import operation.Ensure that the User Name column of your CSV file contains the full email address (for example, [email protected]) for each of your users, or you will receive an error when you upload the file.

Can multiple users use the same Office 365 account?

Microsoft Office 365 works on multiple PCs, and it can use on up to 5 devices simultaneously as well. However, it has to be the same account and either directly subscribed or part of the Microsoft 365 Family subscription. If you try to sign to more than five devices, Office will sign out of one other device, so the limit is honored. However, for Office for Business, you can install and sign in to Office on 5 PCs or Macs, five tablets, and five phones.

Is Office 365 per user or per device?

Microsoft 365 subscriptions provide per-user licenses, so you must use the same account everywhere. Using Office 365 for home lets, you add more users based on family sharing.
