Listing ExchangeActiveSync users assigned to a specific ActiveSync policy

This process outlines the steps to find all users in an organization assigned to a particular ActiveSync policy

  • Exchange ActivePolicy Name used here is “Admins”
  1. First you need to specify a “variable” for the name of the policy which you wish to extract a report. If you skip this step, you will end up querying ActiveSync mailbox policy for all users in the organization.

To do so, open the exchange management shell and type:

$ActiveSyncPolicyName = (Get-ActiveSyncMailboxPolicy “Admins“).Identity.DistinguishedName

Here, replace Admins with the name of your ActiveSync policy

  1. Now, run the cmd-let which will extract “only” the users assigned with the policyname “Admins”. For ease, ft it to the parameters as shown:

Get-CASMailbox -Filter {ActiveSyncMailboxPolicy -eq $ActiveSyncPolicyName} |ft Displayname, ActiveSyncMailboxPolicy, Servername

DisplayName ActiveSyncMailboxPolicy ServerName

Lee, Bruce Admins Exch5
Rajan, Sunder Admins Exch1
Keating, Ronan Admins Exch1
Ronald, Allen Admins Exch1
Nair, Meera Admins Exch5

So as you can see, these are the list of users assigned the Exchange ActiveSync policy named “Admins”

    It’s funny, I just had a need to do this the other day and had to write my own snippet of powershell to accomplish it. I tried a slightly different approach where the variable doesn’t have to be declared before hand

    Get-CASMailbox | where{$_.activesyncmailboxpolicy -match “”}

  2. Kjell Andorsen Says:

    Ooops, guess it didn’t like my formatting. between the double quotes you would put the name of the activesync policy you’re needing so to use your example of admins it would be Get-CASMailbox | where{$_.activesyncmailboxpolicy -match “Admins”}

    I recently needed to pull all users with a particular ActiveSync policy. With over 100k mailboxes in our environment, this is exactly what I was looking for! Since I’m not an “Exchange guy” anymore, but script quite a bit of PowerShell for AD, I would have been fumbling thru the various Exchange PS cmdlets for hours. Thank you very much for posting this blog entry!

    I took Kjell’s one liner and took it a little further. This will grab only the mailboxes with Active Sync enabled, as they are the only ones I care about, and output their name and the policy they are attached to:

    Get-CASMailbox | where {$_.ActiveSyncEnabled -eq “True”} | Select-Object Name,ActiveSyncMailboxPolicy |Sort-Object ActiveSyncMailboxPolicy
