Fix Teams Mobile Sign-In Blocked by Intune After Licenses Removed
Question details
Multiple users are unable to access the Microsoft Teams mobile application due to recurring Intune authentication prompts, despite the organization no longer using Intune.
- Product
- Microsoft Teams
- Device & OS
- Mobile (iOS/Android)
- Scenario
- Users are attempting to log into the Microsoft Teams mobile app using their organizational accounts after Intune licenses were previously removed.
- Observed behavior
- The authentication process is interrupted and blocked by an Intune enrollment or compliance prompt, preventing successful sign-in.
Ensure you have access to a Microsoft 365 Global Administrator account, as resolving residual tenant-level device management policies requires backend administrative access.
Submit a Service Request via the Microsoft 365 Admin Center
Because the issue involves backend tenant configurations and stale device management policies, Microsoft support engineers must intervene to clear the block.
When an organization stops using Intune and removes the licenses, residual device management records or conditional access policies can sometimes remain cached in the tenant's backend. This causes the authentication servers to mistakenly prompt mobile users for Intune enrollment. End users cannot bypass this locally; it requires a backend reset by Microsoft Support.
Navigate to the Microsoft 365 admin center (admin.microsoft.com) and sign in with your Global Administrator or Support Administrator credentials.
On the left-hand navigation menu, click on 'Support' and then select 'Help & support' or 'Service requests'.
Click to create a new service request. Clearly state that Teams mobile sign-in is being blocked by Intune prompts for several users, explicitly mentioning that all Intune licenses were removed years ago.
If you are not an administrator, or if the listed support contact is no longer valid, ask another eligible Microsoft 365 administrator to submit the request on your behalf or update the contact directory.

Frequently Asked Questions
Why is Intune still blocking Teams sign-in if our licenses were removed?
Even after Intune licenses are unassigned, residual Conditional Access policies or Mobile Device Management (MDM) records may remain cached in your Microsoft 365 tenant's backend. The authentication system still reads these stale records, triggering the prompt.
Can I bypass the Intune prompt on my mobile device?
No, end users typically cannot bypass this prompt by reinstalling the app or clearing the cache because the block is enforced at the tenant level. A Microsoft 365 administrator must resolve the backend issue through Microsoft Support.
How do I find out who my Microsoft 365 administrator is?
You can usually identify your administrator by checking your organization's internal IT directory, or by looking for the IT helpdesk contact information provided when you initially received your company email account.
