Best practices: Open OneDrive/SharePoint sharing but restrict Teams guest access by domain
Hi all, Since SharePoint Online and OneDrive moved fully to Microsoft Entra B2B for external sharing, we've run into a policy conflict and would like to hear how others are handling it. Our requirements Enable OneDrive and SharePoint file sharing with external users, regardless of their email domain. Restrict Microsoft Teams guest access to a predefined list of approved partner domains. Continue allowing Teams external access (federated chat and meetings) for all domains. The problem: Teams guests, SharePoint guests, and OneDrive guests are now governed by the same Microsoft Entra B2B invitation framework and the single Collaboration restrictions allow/deny list under: External Identities → External collaboration settings As a result, restricting guest invitations by domain also restricts OneDrive and SharePoint sharing for domains not on the allowlist. According to Microsoft's response in the following Q&A, this behavior is currently by design: https://learn.microsoft.com/en-us/answers/questions/5954975/onedrive-external-sharing-no-longer-working-with-a Questions to the community Has anyone implemented a solution where OneDrive/SharePoint sharing remains open to all domains while Teams guest access is restricted to approved domains only? Are there recommended approaches using Entitlement Management, Access Packages, Connected Organizations, or other Entra capabilities? Is there any roadmap item for workload-specific collaboration restrictions (e.g., separate policies for Teams guest invitations and SharePoint/OneDrive sharing)? Any real-world experience or best practices would be greatly appreciated. Thanks, BejhanPHS staged rollout works for existing users but not new synced users
We are troubleshooting an Entra ID PHS staged rollout issue with a federated domain using a third-party WS-Fed IdP. The intended behavior is that normal federated users redirect to the IdP, while users in the PHS staged rollout group receive the Microsoft/Entra password prompt instead. Existing users in the staged rollout group continue to work correctly. They enter their UPN and receive the Microsoft password prompt. One known-good test user is not provisioned in the third-party IdP and still signs in successfully through the Entra password prompt, so the working path does not require the user to exist in the IdP. The issue is only with newly created AD-synced users. Newly synced users in the same staged rollout group are still being routed to the federated IdP at HRD instead of receiving the Entra password prompt. We’ve verified the staged rollout policy and group membership from Graph, confirmed the affected users are properly AD-synced with clean immutableID/sourceAnchor, and confirmed PHS is working. Federation metadata and HRD policies also look clean. Seamless SSO/AZUREADSSOACC was checked and remediated, but the behavior did not change. For failed attempts, there is no Entra sign-in log entry, including tenant-wide interactive and non-interactive logs. However, the federated IdP logs show a WS-Fed inbound request from login.microsoftonline.com for the affected user. That makes it look like Entra HRD is routing the user to federation before sign-in logging or token issuance. The issue started around an Entra Connect AD connector/DC-path change. We have since reverted the connector to the previous known-good configuration. After reverting, we created a clean-room test user with the correct UPN set before first sync, confirmed sync/PHS/sourceAnchor, added the user directly to the staged rollout group, and waited 60+ minutes. The clean-room user still redirected to the federated IdP instead of getting the Entra password prompt. So the current behavior is that established staged-rollout users still get the Entra password prompt, but newly created synced staged-rollout users are sent to the federated IdP by HRD. Has anyone seen staged rollout get into this state, where existing users work but new synced users remain on the federated HRD path despite valid rollout policy, group membership, synced password hash, and clean immutableID/sourceAnchor? Is there any known backend cache/state reset or escalation path for HRD/staged rollout routing?
Am trying to create group with dynamic user membership using attribute "Employee Type"
Am trying to create group with dynamic user membership using attribute "Employee Type", tried to get details from Extension attribute but didn't find any option, Did anyone tried this and able to do ? I found a posting where it said to create a custom attribute that would be populated by the 'employee Type' field. That just seems a little strange to me to to create an attribute to be exactly like the one that is already there.
Can External ID (CIAM) federate to an Azure AD/Entra ID tenant using SAML?
What I'm trying to achieve I'm setting up SAML federation FROM my External ID tenant (CIAM) TO a partner's Entra ID tenant (regular organizational tenant) for a hybrid CIAM/B2B setup where: Business users authenticate via their corporate accounts (OIDC or SAML) Individual customers use username/password or social providers (OIDC) Tenant details / Terminology: CIAM tenant: External ID tenant for customer-facing applications IdP tenant: Example Partner's organizational Entra ID tenant with business accounts Custom domain: mycustomdomain.com (example domain for the IdP tenant) Configuration steps taken Step 1: IdP Tenant (Entra ID) - Created SAML App Set up Enterprise App with SAML SSO Entity ID: https://login.microsoftonline.com/<CIAM_TENANT_ID>/ Reply URL: https://<CIAM_TENANT_ID>.ciamlogin.com/login.srf NameID: Persistent format Claim mapping: emailaddress → user.mail Step 2: CIAM Tenant (External ID) - Added SAML IdP (Initially imported from the SAML metadata URL from the above setup) Federating domain: mycustomdomain.com Issuer URI: https://sts.windows.net/<IDP_TENANT_ID>/ Passive endpoint: https://login.microsoftonline.com/mycustomdomain.com/saml2 DNS TXT record added: DirectFedAuthUrl=https://login.microsoftonline.com/mycustomdomain.com/saml2 Step 3: Attached to User Flow Added SAML IdP to user flow under "Other identity providers" Saved configuration and waited for propagation The problem It doesn't work. When testing via "Run user flow": No SAML button appears (should display "Sign in with mycustomdomain") Entering email address removed for privacy reasons doesn't trigger federation The SAML provider appears configured but never shows up in the actual flow Also tried using the tenant GUID in the passive endpoint instead of the domain - same result My question Is SAML federation from External ID to regular Entra ID tenants actually possible? I know OIDC federation to Microsoft tenants is (currently, august 2025) explicitly blocked (microsoftonline.com domains are rejected). Is SAML similarly restricted? The portal lets me configure everything without throwing any errors, but it never actually works. Am I missing something in my configuration? The documentation for this use case is limited and I've had to piece together the setup from various sources. Or is this a fundamental limitation where External ID simply can't federate to ANY Microsoft tenant regardless of the protocol used?Orphaned TPM-bound Entra Workplace Join device — no tenant access, backend deletion required
I have a personal Windows device that remains stuck in a TPM-protected Workplace Join to a former Microsoft Entra ID tenant. I no longer have tenant access and am not an admin. Local remediation completed: - dsregcmd /leave executed as SYSTEM - All MS-Organization / AAD certificates removed - Device still reports WorkplaceJoined : YES Azure Support ticket creation fails with: AADSTS160021 – interaction_required Application requested a user session which does not exist. Tenant inaccessible / user not present in tenant. This is an orphaned Entra ID device object. Requesting guidance or escalation for backend deletion. Tenant ID: 99f9b903-8447-4711-a2df-c5bd1ad1adf7 Device ID: f47987f4-a20b-4c34-a5f7-40ab0f593c6cMade a self-hosted Entra ID governance portal for app/identity sprawl (open source)
Our tenant ended up with hundreds of app registrations and enterprise apps, and the native portal makes you dig through a separate blade for every basic question. Who owns this app? Which secrets die next month? What hasn't been signed into in a year? Which ones have scary Graph permissions? There's no single view for any of it, and half the ownership info was missing anyway. Entra ID Governance, access reviews, PIM all exist, but they felt heavy (and licensed) for what I actually wanted, which was just a fast list I could scan for routine cleanup. So I built one. Lightweight portal that runs entirely in your own subscription: One grid for App Registrations, Enterprise Apps, Managed Identities and Privileged Users Risk flags per identity: expiring/expired creds, high-risk permissions, no owner, stale sign-in, no CA coverage Ownership tracking, review and owner-change workflow, CSV export Tenant health score and a consent posture dashboard Optional expiry email notifications (needs a SendGrid key) Reads Graph through a managed identity, so no app secrets for data access and nothing leaves your tenant Runs about $26-30/month (one B2 App Service plan). B1 is also supported, but it's noticeably slower. It's not a replacement for Entra ID Governance or PIM, more of a cheap everyday hygiene thing. Full disclosure, I used AI building this and writing this up. I designed the architecture and functionality, tested it and ran it against my own tenant. It's open source and deployable with Azure DevOps or an Azure CLI script. Data never leaves your own tenant. Repo (screenshots + setup): https://github.com/nicolaibaralmueller/entra-identity-governance-portal Would love feedback, especially what you'd want it to flag that it doesn't, or where the risk scoring feels off. Been building it on and off for a few months with a lot of iteration. Hopefully this could be useful for others as well.
Fido passkeys blocked by policy
Hi all I'm helping out a customer with deploying physical passkeys and I'm running into a weird error. I've activated the sign in method and selected the two AAGuids for the Authenticator app and I've added the right AAGuid for the brand and model of passkey we are using. We can select the authentication method and enroll the security correctly but when trying to sign in using it we get the error as displayed in the attached picture. When checking the sign in logs i get this error message FIDO sign-in is disabled via policy and the error code is: 135016 I've not been able to track down any policy that would be blocking passkeys. anyone got any ideas?'Registering user becomes local admin on Joined Devices' - WHAT
Stumbled on a tenant with 'JOIN' available for all users. Haven't worked with this much - most tenants I see only have registration. But then I noticed the horrifying 'Registering user is added as local administrator on the device during Microsoft Entra join' option was ALSO set to ALL. This is a tenant we just took on, but I've never seen that control before. This is terrifying, considering AFAIK, there is no real way for a registering user to know if they're registering or joining. Beneath it is an option to 'Manage Additional local administrators on all Microsoft Entra joined devices', which leads to the Role page for Device Administrators, which is empty. Under Description, this describes what APPEARS to be to be the same thing mentioned in the previous control - 'Users with this role become local machine administrators on all Windows 10 devices that are joined to Microsoft Entra'. But no one is assigned this. Conveniently, on my own tenant, I happened to let someone JOIN yesterday. We have this limited to 2 (now 3) people - most just register... But this user Joined, and the 'Joining user becomes local admin' option was on ALL. But I can't validate that the user ever become local admin. They don't have the role, their device shows as joined, but there's no additional roles. The audit logs don't look weird. They're not in that 'Device Administrators' group, which describes itself as 'Users with this role become local machine administrators on all Windows 10 devices that are joined to Microsoft Entra'. Thoughts? Freaking out, honestly. We have a mix of DC and Cloud users. I've inherited them all, and had the understanding that Join was essentially registration but with Org ownership. I've tried to get some input from Copilot, but he has basically waffled between 'No, this setting is just badly named' and 'no, actually it's this other setting' and 'no, you know what, it all makes sense somehow'. 1. Does that option actually set the joining user as global admin? Is that really the default setting? 2. can you validate this ANYWHERE in Entra? Or does it just disappear? 3. what is that Device Admin group? A separate group, independent of these two settings, that gives local admin? 4. Is there a graph endpoint that can be used to set this? ThanksMyapplications.microsoft.com and managing applications
We have begun testing the new Myapplications.microsoft.com site. One thing we have noticed is the inability to manage the users who have access to an enterprise application. In the older MyApps site, a delegated user listed within the self-service properties of an enterprise application, could manage and invite guest users (if they have been added to the Guest Inviter role) to their application. However, when trying to do the same thing on Myapplications.microsoft.com brings up the following message on the Permissions and Accounts tab: "This app does not have any accounts." Has anyone else experienced this issue? We currently have Azure AD P1.
