Hello @Andrew Fitzgerald,
I see that the case was successfully resolved with the help of Microsoft Azure Support. I’m posting the resolution here so that other users experiencing the same issue can refer to the troubleshooting steps and resolution.
Issue
The user received the error “The account is blocked, please contact your administrator”, and the Azure DevOps organization xxx was no longer visible in the user's profile.
Steps followed by Microsoft Support
Verified the Microsoft Entra ID account Support initially checked whether the user account was disabled, blocked, or deleted in Microsoft Entra ID.
Checked Azure DevOps organization access They investigated whether the user was still a member of the Azure DevOps organization and whether the required Azure DevOps access/licensing was available.
Investigated the organization-to-tenant association Microsoft checked their backend systems to determine which Microsoft tenant the Azure DevOps organization was associated with.
Identified a tenant connection issue Further investigation showed that the tenant hosting the AzureListings Azure DevOps organization had become disconnected, which was preventing access to the organization.
- Confirmed the correct tenant ID The customer confirmed that the correct Microsoft Entra tenant was:
xxxxxx
Reconnected the Azure DevOps organization Microsoft Support reconnected the AzureListings organization to the confirmed tenant.
Verified access After the reconnection, Microsoft confirmed that the organization was accessible again and that the issue was resolved.
Closed the support case Once access was restored and the resolution was confirmed, Microsoft proceeded with closing the support request.
Resolution
The issue was ultimately caused by the Azure DevOps organization's connection to its Microsoft Entra tenant becoming disconnected. Reconnecting the AzureListings organization to the correct tenant (xxxxx) restored access and resolved the issue.
If you are experiencing the same symptoms, checking the organization's tenant association with Microsoft Support may be necessary, particularly if the Entra tenant itself is active but the Azure DevOps organization has disappeared from the user's profile.
If this answer helped resolve the issue, please accept it as the answer so that other community members facing the same problem can easily find the resolution.
