Get ActiveSync Users

When you have almost 30,000 mailboxes, managing ActiveSync can become a nightmare.  The nice thing about ActiveSync is that is just works.  There is not too much configuration to get it setup, but if you do not plan ahead, you can find yourself in the same predicament as us and have 1500 people connecting through some sort of mobile device without any sort of security policy.  This is a huge security risk, and to combat it we are slowy implementing security policies by agency. So the first step in my process was to get a list of all users that have connected in the last 30 days.

So this way takes a long time if you have lots of mailboxes. For example, this takes over 55 minutes to complete in our environment. But if you do not have a lot of mailboxes, then this method should work fine for you. This report will create a CSV, and list the users name, and type of device.

Get-Mailbox -ResultSize:Unlimited | ForEach {Get-ActiveSyncDeviceStatistics -Mailbox:$_.Identity -ErrorAction SilentlyContinue}| Where{$_.LastSuccessSync -gt '01/01/11'} | Sort-Object -Property DeviceType,Identity | Select-Object @{name="EmailAddress";expression={$_.Identity.ToString().Split("\")[0]}},DeviceType | Export-Csv -Path:"c:\MobileDevices.csv"

One of the bad things about the above script is it will more than likely return some dupilcates. So to combat that, I added a where statement just so I can get the devices that have synced in the last 30 days.

get-mailbox -ResultSize unlimited -Filter {EmailAddresses -like "*@email.com" } | ForEach {Get-ActiveSyncDeviceStatistics -Mailbox:$_.Identity  -ErrorAction SilentlyContinue}| where {$_.lastsuccesssync -gt '02/01/2011'} | Sort-Object -Property DeviceType,Identity | Select-Object @{name="EmailAddress";expression={$_.Identity.ToString().Split("\")[0]}},DeviceType

Ok, now here is a quick way of doing the same thing but by using a filter. I recommend always using a filter to get your results. In this example we are filtering on EmailAddresses and only listing those people that have synced a device in the last 30 days. I spent a few hours trying to figure out how to best do this, and this is the best I could come up with. Please leave a comment if you know of a better way.

get-mailbox -ResultSize unlimited -Filter {EmailAddresses -like "*@email.com" } | ForEach {Get-ActiveSyncDeviceStatistics -Mailbox:$_.Identity  -ErrorAction SilentlyContinue}| where {$_.lastsuccesssync -gt '02/01/2011'} | Sort-Object -Property DeviceType,Identity | Select-Object @{name="EmailAddress";expression={$_.Identity.ToString().Split("\")[0]}},DeviceType | Export-Csv -Path:"c:\MobileDevices_email.com.csv"
