Hey everyone, I need some advice! When we initially set up our Microsoft 365 tenant, we used our old company name. Now that we've rebranded and want to keep everything aligned, we'd like to rename our tenant. We're mainly focused on using SharePoint to share documents with external partners, and we want the shared links to reflect our current name.
I reached out to our 365 admin, who contacted Microsoft support, but they said we can't rename the tenant. Our only option seems to be migrating to a new tenant. However, I've seen numerous posts and even some official Microsoft guides suggesting that renaming can be done. I'm not the 365 admin myself; I'm just looking for the best solution for our company with minimal disruption.
Has anyone successfully navigated this situation recently? I'd appreciate any insights or experiences you can share!

From what I've seen, it looks like you're looking at a hard situation. Changing the email sending/receiving domain is doable, but the underlying tenant name can't be altered. There are migration tools that can help, but expect some impact on your users no matter what.
Just a heads up, you can’t fully rename a tenant—it’s more about changing certain URLs. Proceed with caution, as some things will remain linked to the old name.
Check out this guide for potential solutions: [Changing Your SharePoint Domain Name](https://learn.microsoft.com/en-us/sharepoint/change-your-sharepoint-domain-name). We managed to do this a few years back for our team, and it worked out well for around 100 users without a hitch.
You definitely have some options! You can rename the SharePoint URL from your old domain to the new one, but keep in mind that after a year, the old links will stop working. If you're a multi-geo tenant, though, you might be out of luck—it’s not supported as of now. Also, adding a new onmicrosoft domain is possible, but you’ll never fully remove the old one—it’s a permanent part of your tenant.
You might consider a workaround by changing the primary domain. While it won't be a complete fix, at least your users will have emails that reflect the new domain. Just a heads up, the optics might not be ideal.
Look at it this way: it’s a good opportunity to tidy things up! You might need to create a new tenant to do everything right, but it could lead to a more organized setup with best practices in place.
