Manged Home Screen: Outlook
We are running into issues with the Managed Home Screen and Outlook.
Once the user has logged into the Managed Home Screen and tries to access Outlook, it gets stuck in an authentication loop.
Loops: Discovering Accounts -> Accounts Found -> Back to Discovering accounts.
This is affecting multiple devices/accounts.
This only affects

Hi CSJackA
We have the same problem. Have you solved?
We've used MHS on shared devices with SSO for a couple of years.
Now all MS Apps work except Outlook, which ends in a loop without any diagnostic error.

Unfortunately not, I haven't even had a response on my ticket with MS.
We have also experienced the same issue over the past two weeks.
Hi CSJackA,
Did you already check the follwing?- Conditional Access and App Protection Policies — no conflicts or missing scopes
- Cleared Outlook cache/data and reinstalled the app
- All apps (Outlook, Managed Home Screen, Company Portal, OS) are fully updated
- Tested on a non–Managed Home Screen device (to rule out kiosk mode issues)
- Reviewed Azure AD / Entra ID sign-in logs for blocked or failed authentications
- Tried a temporary workaround — e.g., using Outlook Web Access or disabling auto sign-in
We've also checked all of the above. Even if we exit Kiosk mode the Microsoft apps still don't work, they all get stuck in a constant loop of trying to add the users account. Outlook web app works but we need the devices to access Teams as well which doesn't work in the browser of Android devices.
This was all working fine until recently, we've not changed anything in relation to policies.
Hi Emre,
To answer your questions:
- Conditional Access and App Protection Policies — no conflicts or missing scopes:
No issues with it going through the conditional access and app protection policies. - Cleared Outlook cache/data and reinstalled the app:
Complete reinstall of the device and apps doesn't resolve the issue. - All apps (Outlook, Managed Home Screen, Company Portal, OS) are fully updated:
All apps and OS are fully up to date - Tested on a non–Managed Home Screen device (to rule out kiosk mode issues):
This is an issue with the Kiosk mode only - MSAL seems to be the issue - Reviewed Azure AD / Entra ID sign-in logs for blocked or failed authentications:
No failed authentication on the user account, sign-in logs show "Success" - Tried a temporary workaround — e.g., using Outlook Web Access or disabling auto sign-in:
OWA works, however, doesn't resolve the underlying issue with the kiosk mode not signing in the account to the full version of Outlook.
- Conditional Access and App Protection Policies — no conflicts or missing scopes:
We're getting the exact same issue today, it was definitely working fine previously with the same devices/accounts.
We had the same thing, it worked when we rolled it out 6 months back, but has broken since September/October.
