Windows Live Custom Domains causes Entra account lockout
Hi everyone, we have an on-prem AD connected with EntraConnect to EntraID since about 3 years. We only sync users and groups, no password hash or anything else. Since a few days 4 (out of about 250) users are constantly being locked out due to failed login attempts on an Application called "Windows Live Custom Domains". All 4 users are locked out not at the same time but within 30 min to an hour. This happens multiple times a day. As far as I was able to investigate Windows Live Custom Domains is a service no longer offered by MS or has been replaced with something else. How am I able to find out where this failed login attempts come from? If someone could point me in the right direction I would be very happy. Thanks Daniel
Exclusion of Copilot App (for O365) from Conditional Access Policies does not work
Hi, we've built a Conditional Access Policy in EntraID that forces MFA for all Cloud Apps. We want to exclude "Microsoft 365 Copilot"/ "Copilot App" so no Reauthentication is necessary for Copilot in the frame of accessing O365 content. Exclusion has been made for a range of identified Copilot applications that are shown in Sign-in logs. However, reauthentication still pops up. No other conditional access policy is applied. It's this specific policy that requires reauthentication. What's the reason why the exclusion does not work? Is there something else necessary to be taken into consideration so the exclusion works fine? Many thanks in advance!
External ID login page not showing identity providers
I am trying to create a login flow using an custom OIDC identity provider, but the login page is just showing a prompt for email and password without a way to log in using the external identity provider. I have configured the identity provider in Entra, and created a new user flow that should include the identity provider. Additionally, when an application is added to the user flow, any login using that application shows an error saying "We couldn't find an account with this email address" when trying to log in with a user that was working previously. I'm not sure if this is related to the missing identity provider or not. Is there a way to fix this? Any help is appreciated!Access Package Assignment Issue
Hello, We have an access package that was functioning properly in the past, but the assignment process has stopped working. The issue started on August 22; the last successful assignment was on July 29. When attempting to manually assign the access package to an external user, we receive the following error: "You don't meet policy requirements to request this entitlement." Additional details: The configuration of the policy has not been changed. Users who can request access is set to “None (administrator direct assignments only)”. Changing the “Enable new requests” setting (enabled/disabled) does not resolve the issue. Expiration is set to 90 days. This access package is intended for external users, but I tested assigning it to an internal user and it works correctly. At this point, I do not have additional information about what might be causing the issue. Could you please help us identify the root cause and suggest next steps? Thank you for your assistance. Kind regards,
Email OTP not working for guest users
We have to enable MFA using Email for some guest users accessing some of our Entra applications. Guest users are from other Microsoft tenants, B2B collaboration users. We have it all set up in the Authentication methods and in Conditional access policies. Also excluded this user's security group from System-preferred multifactor authentication. When the guest user connects to the application or to the tenant portal, it's still prompting to register for MFA using authenticator App. how can we make it to use an email one-time code please ?

MFA breakglass account recommendations?
Hi folks. Looking at the new Authentication Methods settings, and trying to consider the scenario where someone disables all of these methods by accident. We require MFA on all accounts (using the 'require MFA' param of Conditional Access). If these are all disabled, there's no MFA method available... Trying to think of ways around this, for that situation. Things I've considered - cert based auth, telephone auth, etc - all require the corresponding auth method to be enabled. How should this be handled?Join Merill Fernando and other guests for our Identity and Network Practitioner Webinar Series!

Hi, we've built a Conditional Access Policy in EntraID that forces MFA for all Cloud Apps. We want to exclude Microsoft Edge Browser so no Reauthentication is necessary for MS Edge Browser.

We have configured API-driven provisioning for on-premises Active Directory, along with Azure AD Connect, to synchronize on-premises AD users with Azure Entra ID. As part of the provisioning setup, we have used a separate Organizational Unit (OU) in on-premises AD (designated as the default OU for new users) while configuring API-driven provisioning. We are attempting to make some changes to the API field mapping, specifically the ‘UserPrincipalName’ regular expression (custom domain) and the ‘manager’ field, and saving the configuration. Upon attempting to save, a prompt appears (as highlighted below screenshot), indicating that this action will resynchronize all users and groups. Could you please clarify: Will this resynchronization update any existing users outside the default provisioning Organizational Unit (OU)? Specifically, what does the resynchronization operation update? For instance, will it modify the 'UserPrincipalName' and 'manager' attributes for all users including old users outside of provisioning Organizational Unit (OU)?

With the latest update to Microsoft Defender for Endpoint on iOS, Organisations licensed for Microsoft Entra Suite or Microsoft Entra Internet Access will have access to Microsoft's Secure Web Gateway (SWG) and traffic forwarding for HTTP/HTTPS traffic, with support for Web-Content Filtering. This has been a huge win for iOS Mobile Security. Previously, Defender for Endpoint on iOS has supported Phishing Protection, M365 Traffic, and Entra Private Access Traffic. Combined with Global Secure Access Threat Intelligence, which consumes indicators from Microsoft Intelligent Security Graph (ISG), Organisations can implement granular internet access controls on iOS devices with integrated, context aware protection against malicious threats. Excited to hear what you think! Release notes are available hereMicrosoft Entra Connect connecting always to old DC
We are planning on demoting old DC server. When doing checkups I noticed that Entra Connect keeps connecting to this specific DC we'ew planning to demote everytime it connect to Active Directory. So now I'm wondering does this need any additional configuration to keep sync working after DC Demote. I found out that there is option to "Only use preferred domain controllers" but I'm not sure if that's what I want do do. There were the red line is is the old DC to be demoted. "Only use preferred domain controllers" setting. If I enable this setting I got this kind of notice. I don't feel like this is the right way to do it so I canceled at this point.
Restrict access to Microsoft Entra admin center
Hi, I know that setting this to Yes isn't considered a Security measure by Microsoft, but I really think that they need to rethink this and give a better warning Entra>Users>User Settings>Restrict access to Microsoft Entra admin center If this is left to, No, which is the default, then any user (Admin or Standard User) is able to access Entra, and for certain things this may be required, but it leaves a huge door open as well for the egress of data. For example, a Standard user can access Entra, select Users and or Devices from the left hand side and export a .csv file with all devices listed and or all Users in the estate listed with a lot of other information in this as well that is included in the exported file. Is there another way to allow users access to the portal to manage Groups or Apps that they are an Owner on (which is one of the reasons that I see for allowing any user to access the portal) but also to dramatically reduce the risk to the business for users also being able to see a lot of other information in Entra that we would not wish users to be able to see or indeed interact with, such as downloading a file of all Devices and Users in the estate.👉 Microsoft Entra in Action: From Conditional Access to Identity Protection
One of the areas I’m most passionate about is identity-driven security. Microsoft Entra makes it possible to apply Zero Trust principles directly at the identity layer. ⚡ Conditional Access – the backbone of modern access policies. 👤 Privileged Identity Management (PIM) – ensuring just-in-time, least privilege for admins. 🛡️ Identity Protection – risk-based policies to stop compromised sign-ins in real time. In my labs, I’ve seen how these features transform security posture without adding friction for users. Coming soon: - Step-by-step breakdown of a risky user detection scenario. - A visual guide to Conditional Access controls for critical apps. Would love to exchange insights with others experimenting in this space — what Entra features are you finding most impactful? #MicrosoftEntra | #ConditionalAccess | #IdentityProtection | #MicrosoftLearn | #PerparimLabs
The salt sizes required for signing with RSAPSS do not match those used by TPM.
Good evening everyone. I'm getting this error when I try to perform the first sync on my Windows Server 2022. I'm trying to sync the entire directory to manage my employees' licenses. I already have a tenant with users who can stay there without any problems. I had already synced the tenant with my old server in the past. For business reasons, the infrastructure has changed, and so has the server. In Entra ID, I don't see any old syncs, but in Admin Center, I do. Could this be the problem? Any advice is invaluable, as I'm at my wits' end.
Unable to add Azure Virtual Desktop Client Enterprise App to Conditional Access
We currently use conditional access to allow certain contractors to sign into VMs, and from these VMs, access other MS Apps. Currently we block all applications from outside the VM ip range, but exclude the Virtual desktop applications to allow the users to do the initial signin to the VM. When contractors are using the Virtual Desktop app, it seems to work ok. However, recently when signing in via the browser only and launching from there, the conditional access rule is blocking them as the application ID isn't in the exclude list, and we are unable to add it: a85cf173-4192-42f8-81fa-777a763e6e2c The documentation: https://learn.microsoft.com/en-us/azure/virtual-desktop/set-up-mfa?tabs=avd shows that web signins may originate from this application ID, but without the ability to add this to the exclusion apps, we cannot find another workaround that allows access via the browser. I also tried adding this app in to the policy via GraphAPI, but I get an error saying that this first party application isn't allowed. I need to know if there is another workaround or if Microsoft are planning to add this to the CA compatibility list? I'm not sure why some of the Virtual desktop apps are there but this one is not.Invite external user - error 'Primary SMTP address is an invalid value'
I'm using Entra Id to invite external users to my domain. Their email is of form: mailto:email address removed for privacy reasons Sending the invite generates the error: There is no error if I send an invitation to the same domain without the '+' sign, so I assume this is causing an issue with Entra Id. Is there a workaround for this?
