Thanks for the confirmation, glad the issue is resolved.
Solution:
The organization's settings had external/guest user access disabled by default, which caused to loose the access to it.
It sounds like your Azure DevOps organization ended up “orphaned” when you renamed it and tweaked permissions, so even though you’re a Global Admin you no longer show up as an active Owner or Project Collection Administrator.
Here’s how to get back in:
- Verify you’re in the right Azure AD tenant • In the Azure portal, use “Directory + subscription” to confirm you’ve selected the same Entra ID tenant that the DevOps org uses. • Open a private/incognito browser and go to https://dev.azure.com/{YourOrganizationName} (use the new name if you renamed it).
- Claim ownership of the orphaned organization • Make sure your account is a Microsoft Entra Global Administrator and has the Azure DevOps Administrator directory role assigned. • When you sign in to the org URL, you should see a banner or button labeled “Claim ownership” or “Change owner”. • Click it, pick yourself as the new owner, and provide justification. This will re-activate your Owner role.
- Re-inflate your admin group for safety • In Organization settings > Permissions > Project Collection Administrators, add at least two human accounts (yourself plus a colleague) and a break-glass service account or group synced from Entra ID. • Avoid having only a single Owner or PCA—you’ll thank yourself later if someone loses access again.
- Verify your URL and browser state • If you renamed the org, double-check you’re using the updated URL (for example, https://dev.azure.com/new-org-name). • Clear cookies or do an InPrivate session to rule out stale authentication tokens.
If you don’t see a Claim ownership option:
Confirm that the previous Owner and all PCA members are truly inactive (disabled or deleted) in your Entra ID tenantonly then does Azure DevOps expose the orphaned-org recovery controls.
Hope this helps!
