Azure AD Dynamic Groups is not something new. We have this in Exchange for long time but we are also able to use them even in Azure Active Directory with the Azure AD Premium 1 license. Why should we use dynamic groups instead of static groups? In this post I will give you some example where we find the benefit.

Example 1 : Create groups based on what kind of license they have.
If you pinpoint all Azure AD Premium 2 users into a group, then you can deploy risk-based users to this group and all new users with correct license will get the function. How can we archive this?Sign-in to this address

Navigate go groups and create a new group

1, Add security group and select membership to Dynamic User.

2, Add dynamic query

user.assignedPlans -any (assignedPlan.servicePlanId -eq "eec0eb4f-6444-4f95-aba0-50c24d67f998" -and assignedPlan.capabilityStatus -eq "Enabled")

3, Save the query. Based on how many users you have it will take some time before you see the result.

Below you can fins most of the generic ServicePlanId. Find the one you need to query and just change the number in above query.

Example 2: Find all users with Teams license active and list properties
Instead of writing advanced script to list users with a specific serviceId you can use this dynamic query to list all users with Teams enabled, then we can verify with a foreach if the Teams run Teams-only or Islands mode.

$TeamsUsers = Get-AzureADGroupMember -Top 1000 -ObjectId f069085e-f197-4b2e-a17b-2bc79843b770

Foreach ($x in $TeamsUsers)
    $output +=  Get-CsOnlineUser -Identity $x.UserPrincipalName | Select-Object UserPrincipalName, TeamsUpgradeEffectiveMode, TeamsUpgradePolicy
    $output | Out-GridView

Example 3: Enabled Office 365 ATP on only licensed users
Create a dynamic group and select all users with an Office 365 Advanced Threat Protection (Plan 1/2) license. Assign this group to the Office 365 ATP service and only the correct users will get the function enabled. We don´t need to verify if correct users are in correct group anymore. If you assign the user the license they also get the functionality automatically. As you can see I have just a few case but I think you got the point how you should use dynamic groups in many scenarios now.
