I want to shorten the name of my OneDrive business account

Dear @Jorgen Wadum,

Thank you for reaching out to Microsoft Q&A forum.

Correct me if I’m wrong, but I understand that you're looking to shorten the name of your OneDrive in File Explorer or when syncing. The issue is that the name of your OneDrive for Business folder is automatically generated based on your organization's legal name in Microsoft 365. You cannot simply right-click and "Rename" the folder on your computer; doing so will break the sync connection.

To shorten the name, you’ll need to address the source of the name in the tenant settings. This requires admin credentials.

If you are the Global Administrator for your company, you can change the name that appears in everyone’s OneDrive sync folder by following these steps:

1. Go to the Microsoft 365 Admin Center.
2. Navigate to Settings > Org settings.
3. Select the Organization profile tab and click Organization information.
4. Change the Name field to the shorter version you prefer.
5. After saving, your users will eventually see the folder name update from "OneDrive - Very Long Company Name" to "OneDrive - ShortName". Note: Users will need to "Unlink this PC" and sign back into the OneDrive app for the new folder name to take effect locally.

If you're not the Global Administrator for your organization, please reach out to them to perform the steps above. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support  

I hope this information is helpful. Please follow these steps and let me know if it works for you. Thank you for your patience and understanding. If you have any questions or need further assistance, please feel free to share them in the comments so I can continue to support you. I'm looking forward to your reply.

For a OneDrive for Business account, the visible “name” typically comes from two places, and each is changed in a different way:

1. User display name / UPN (sign‑in name)
   This is what appears in many Microsoft 365 experiences and can affect how the OneDrive URL is formed for a specific user (for example, the part based on the User Principal Name prefix).
   • An admin can change the user’s UPN or display name in the Microsoft 365 admin center or Microsoft Entra admin center as described in How UPN changes affect the OneDrive URL and OneDrive features.
   • UPN changes can take several hours to propagate.
2. Tenant/organization name in the OneDrive/SharePoint URL
   If the goal is to shorten the organization part of the URL (for example, from verylongname.sharepoint.com / -my.sharepoint.com to a shorter name), this is controlled by the SharePoint Online domain:
   • The SharePoint domain (which also underlies OneDrive for Business URLs) can be changed using the SharePoint domain rename feature. For example, from contoso.sharepoint.com to fabrikam.sharepoint.com.
   • This operation is done via PowerShell at the tenant level and affects all SharePoint and OneDrive URLs, not just one user.
   • While the rename runs, sites on the old domain are temporarily inaccessible until each is renamed.
   • The feature has limitations (for example, not available for tenants with multi‑geo or certain special/government clouds, and there are limits/considerations around number of sites and specific apps/features).
   • After the rename, redirects from the old domain work for 1 year.

To shorten the “business account name” as seen in OneDrive:

• If the concern is the personal part (user name), an admin should update the user’s UPN/display name.
• If the concern is the long tenant/organization name in the URL, the admin must evaluate and, if appropriate, perform a SharePoint domain rename for the tenant, understanding the scope and limitations.
