Why am I getting error when trying to change a site name, even though it says the new name is available?

I am in the SharePoint admin center and need to change a site name. When I go to Active Sites, General, Edit site name, I get an error message "Site title update has failed."

These steps worked for me, HOWEVER, it does not address the primary issue of why updating a Site name does not work from within the SharePoint Admin Center. My UID is the owner of the Site where this failed. Updating the Site name through the "Edit SharePoint site name" interface in the SharePoint Admin Center failed with the error, "Site title update has failed".

I have performed this action on other Sites within the past 6 months from the SharePoint Admin Center and it worked. It does not work now. Is this related to the Microsoft 365 Outage that happened lastr week? If so, we should be informed of this.

Regardless of the reason, this functionality is an essential feature. in the SharePoint Admin Center and should work, without question or excuses.

Thank you.

Hi @Chris-in-SF
Since this forum is a peer-to-peer community, moderators, contributors including external Microsoft employees do not have access to back-end systems and therefore cannot provide direct explanations for tenant-specific issues. Our role is limited to offering technical guidance based on reported issues, public resources, and shared experiences.
You may try using another SharePoint admin account to see if the issue persists. If it does, the problem is likely related to tenant provisioning. In that case, we recommend submitting a support request through the Microsoft 365 admin center. The Microsoft Support team can then run diagnostic tools and investigate further.
For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.

Hi there,

i've the same problem: We create SharePoints with a PowerAutomate-Flow for customer projects.

After the SP is created with a Shortname (P123123 for example), it gets renamed over Microsoft Teams (via PowerAutomate) to something meaningfuller ("P123123 Project XYZ"). We do this, so that the SharePoint-eMailaddress is set to the project number.

My Problem now is:
- SharePoint gets created and successfully renamed (Created with P202xxx, renamed to "P202xxx_Betriebsbetreuung XXX"):
- As you can see, the "Site name (German)" is the old name. If i try to change it, i get the error "Site title update has failed"):
- Then i thought, maybe its a problem with the display language. My Microsoft-Account is set to "German" as display language. The SharePoint is created with the locatlization "German". The Multi-Language Module within the SharePoint is disabled. Also, the SharePoint is displayed in english with the correct Site name:
- If i check Microsoft Teams, the connected Team is listed with the correct name:
I don't need the Multi-language module. I need one Site title, that's consistent over all languages. I don't know, why i can't change the "Site name (German)" from the SharePoint Admin.

Hi @Bastian
From your screenshots and descriptions, it looks like you were able to change the site title, but the updated name does not appear right away under Sites > Active Sites. This behavior is expected because the change can take several hours to propagate. When you open the site directly, the new title is visible immediately, but the admin list takes time to update.

Have you tried using the PowerShell scripts mentioned earlier to confirm whether the update works in your environment? The behavior is the same there as well, with a delay before the change is reflected everywhere.

If this still does not resolve your issue, could you provide more detail about what happens when you attempt to update the title again? You mentioned that “Site name (German)” remains as the old name and that you receive the error “Site title update has failed”. Sharing more specifics about that error will help narrow down the issue.
