Not able to recreate Teams Sharepoint site after perm deleting.

When you permanently delete a Teams‑connected SharePoint site, Microsoft doesn’t immediately free up the URL. The site object is placed in a “write‑locked” state for a period (often 30 days or more) to prevent accidental reuse or conflicts. That’s why your Rename-PnPTenantSite call fails, the target URL is still reserved, even though the site is gone.

1. Check Deleted Sites in Admin Center
   • Go to SharePoint Admin Center > Sites > Deleted sites.
   • If the old site still appears there, you can’t reuse its URL until it’s fully purged.
2. Force Purge (if you’re a tenant admin)
   • Use PowerShell to remove the deleted site permanently:
     Remove-SPODeletedSite -Identity https://tenant.sharepoint.com/sites/OldSiteName
     This clears the URL reservation.
     Note: Even after purge, Microsoft may hold the URL for a short retention period.
3. Wait for URL Release
   • Microsoft sometimes enforces a cool‑down period before a URL can be reused.
   • If you’ve already purged, you may need to wait until the lock expires.
4. Use a New URL
   • If you need the site immediately, provision it with a slightly different URL (e.g., SiteName2).
   • Later, when the original URL is released, you can rename again.
