Migrating from Hybrid to pure Azure AD
We've currently got our domain/environment setup in a Hybrid AD. We've got a DC with AzureAD Connect installed and syncing to Azure. The plan is to uninstall AzureAD connect, demote the DC server, manually join computers to AzureAD. Will this work? I'm trying to understand if there is any consideration when uninstalling the AzureAD connect or disconnecting the server from Azure. Thanks!
Reachability of a domain across multiple tenants
I have a general question about an Entra scenario that we currently need to implement. Our company consists of 3 companies (companyA.com, companyB.com, companyC.com), each with their own MS Tenant. Here, A is the parent company and B and C are subsidiaries. Is it somehow possible, perhaps with Cross Tenant Synchronization from B, C -> A, that users from the subsidiaries can log in with the parent company's domain name in Entra, Teams & Co., and that Teams invitations can also be sent via an email address of the parent company? So I have mailto:email address removed for privacy reasons and I would like this user to also be known as mailto:email address removed for privacy reasons in the Microsoft ecosystem. From a marketing perspective, it is important that all employees log in and are reachable with the same domain. A migration into one tenant is probably not easily possible for legal reasons. Thank you in advance for your assistance. Christian
Looking for a way to set up mail moderation using Entra dynamic group
Our organization is working on shifting from a hybrid AD-Entra environment to Entra only. We currently use mail-moderated dynamic distribution lists using Extension Attributes to set the rules for mass internal company emails. In conjunction with us migrating to Entra only, we are also planning to use an API integration to manage our Entra account creation and updates. This integration does not have the ability to populate the Extension Attribute fields. Because of these changes we will no longer be able to use the existing dynamic distribution lists we have, and we have not had luck finding a solution for it yet. Has anyone else gone through this or have any experience solving for this same problem?
Block all 365 apps except Outlook via CA
Trying to block 365 for a subset of users, except email. The old app-based CA rules made this easy. The new 'resource' based setup... I'm not even sure if it's possible. CoPilot just keeps telling me to use the old version of CA, because it hasn't clued into Microsoft's downgrade cycle. If I try to filter by resource attribute, I'm told I don't have permission to do so. I'm the global admin. Here's what searching for Outlook gives me and Exchange Advice? We ARE intune licensed, but i'm not sure App Protection Policies will help here. The intention is to block BYOD from accessing anything but Outlook / Exchange. That is, Mobile devices that aren't (whatever param I decide on)
How to recover or re-add device
Hi, To try and make a long story short, I have 2 devices, Device 1 one belonged to me and Device 2 belonged to someone previously. I had taken Device 2 because the specs we're better and am giving Device 1 to a new-hire. My initial thought was to delete Device 1 and just re-add it to Azure AD under the new owner. After I had done that I came across an extremely simple PowerShell cmdlet that made adding a new owner and removing the old owner very fast and painless. I used this cmdlet to add me as the new owner of Device 2 but had already deleted Device 1. I'm now stuck trying to figure out how to get Device 1 back into AD and change the owner. How can I do this? Thanks
👉 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
Sign In Error 90072 with On Prem Accounts - How to mitigate?
We receive weekly reports from one of our security vendors regarding login failures across our environment. As of recent, we've noticed a spike in interactive login failures, particularly with Microsoft services. The application that produces many of these logs is Microsoft Office. Upon investigation, we've determined that many of these sign ins procure error code 90072 with the following error message: "User account '{user}' from identity provider '{idp}' does not exist in tenant '{tenant}' and cannot access the application '{application}'({appName}) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account" As a disclaimer, I did not edit this message to insert the unfilled variables in brackets - that's how the error message appears in our Entra portal. We currently run a hybrid environment, and all of the users with high volumes of failed sign ins with the given error code and message are on-prem accounts. These logs produce a lot of noise that we would rather not have polluting our reports. Do you have any information we can use to help remediate this issue?Shape the future of our communities!
