Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi @Gregory Kendig,
Welcome to the Microsoft Q&A forum.
Thank you very much for reaching out regarding the setup issue with your Microsoft 365 Business Standard subscription. I appreciate your patience and the details you provided.
I understand that you’ve just purchased Microsoft 365 Business Standard and that the setup wizard keeps crashing, preventing you from adding users.
To help you move forward right away, please try the steps below in order:
1/ Confirm your subscription is fully active
Sign in to https://admin.microsoft.com using your Global admin account (the one ending with your organization’s onmicrosoft.com domain, not a personal account such as Outlook.com or Gmail.com).
- Go to Billing > Your products and ensure Microsoft 365 Business Standard shows as Active and that you have available licenses.
-
Create backup Global administrator
To ensure continuous and secure access to your tenant, I recommend creating an additional user with the Global Administrator role. This serves as a backup in case the primary administrator is unable to access the tenant. The backup Global Administrator can assist with tasks such as resetting passwords and maintaining access control.
Here are the steps to add a new Global Administrator:
- Sign in to the Microsoft 365 admin center with your current Global Administrator account.
- Navigate to Users > Active users.
- Select Add a user and fill in the necessary details for the new user.
- Assign the Global Administrator role to this new user.
-
- Save the changes and ensure the new administrator receives their login credentials.
By having a backup Global Administrator, you can enhance the security and reliability of your tenant management.

2/ Use a clean browser session
- Open an InPrivate/Incognito window in Edge or Chrome (no extensions), sign out of any other Microsoft accounts, then sign back in using only your admin account.
-
3/ Add a user manually
To add a user manually:
- Go to Users > Active users > Add a user
- Enter the Display name and Username
- Select Automatically create a password, and keep Require this user to change their password enabled
- Under Product licenses, turn on Microsoft 365 Business Standard (make sure the correct location is selected)
- Select Finish, then confirm the user appears in your list of Active users
- Send the generated login information to the user (optional)
To add multiple users at once:
- Use Bulk add in the Active users page (you can download the CSV template directly from the Admin Center)
- Or use the Microsoft 365 Admin mobile app to add users quickly
4/ Add custom domain
Once you have the domain, you can add it to the tenant through the admin center. You can follow these steps: Also, in this doc. Add a domain to Microsoft 365 - Microsoft 365 admin | Microsoft Learn
- Sign in to the Microsoft 365 admin center with your admin credentials.
- Go to the "Domains" page and click on "Add domain" >Enter the domain name you want to use and click on "Next".
- Follow the prompts to verify your domain ownership. Once your domain is verified, you can create user accounts and assign licenses to them.
- To create the Microsoft accounts under one tenant for a domain, you can follow these steps:
- Sign in to the Microsoft 365 admin center with your admin credentials.
- Go to the "Users" page and click on "Active users".
- Click on "Add a user" and enter the required information for each user.
- Assign licenses to each user as needed.

5/ Contact Support
If the issue continues after completing these steps, I recommend opening a support ticket directly with Microsoft Support. They have access to system‑level diagnostics and can investigate the problem more thoroughly. At the very least, they can provide the most effective workaround to ensure your experience remains smooth and secure.
Please follow the steps below:
- On right bottom corner click on "Help & support"
-
- After that choose the "Contact support".
-
- Describe your issue and request to speak with a live agent. You may be offered options for chat or call depending on your region and support availability.
