Hi, 
 
You can see on the present policy: 
&nbsp;Get-ThrottlingPolicy | fl EAS*
</div>

<div>
When I run the command: 
[PS] C:\Users\admin\Desktop&gt;Get-ThrottlingPolicy | fl EAS* 
 
 
EASMaxConcurrency &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 10 
EASPercentTimeInAD &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;: 
EASPercentTimeInCAS &nbsp; &nbsp; &nbsp; &nbsp; : 
EASPercentTimeInMailboxRPC &nbsp;: 
EASMaxDevices &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 10 
EASMaxDeviceDeletesPerMonth : 
 
EASMaxConcurrency &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 10

EASPercentTimeInMailboxRPC &nbsp;: 
EASMaxDevices &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 10 
EASMaxDeviceDeletesPerMonth : 
 
How do I set max number of devices for all mailboxes to 20?
</div>

<div>
I searched and found this command: 
 
New-Throttlingpolicy &quot;Increased ActiveSync Devices&quot; -EasMaxDevices 20 -EasMaxConcurrency 20 
 
When I ran in my Exchange Shell window, it took it. 
I ran Get-ThrottlingPolicy | fl EAS* and it showed the following: 
EASMaxConcurrency &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 10 
EASPercentTimeInAD &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;: 
EASPercentTimeInCAS &nbsp; &nbsp; &nbsp; &nbsp; :

EASPercentTimeInMailboxRPC &nbsp;: 
EASMaxDevices &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 20 
EASMaxDeviceDeletesPerMonth : 
 
I tried to apply the policy by running: 
Set-Mailbox $MAILBOX -ThrottlingPolicy &quot;Increased ActiveSync Devices&quot; 
 
But this generated an error: 
 
Cannot bind argument to parameter 'Identity' because it is null.

</div>

<div>
When I ran - Get-Mailbox -RecipientTypeDetails UserMailbox | set-mailbox -ThrottlingPolicy &quot;Increased ActiveSync Devices&quot;, it went successfully.

(1) What is the difference between: 
Get-Mailbox -RecipientTypeDetails UserMailbox | set-mailbox -ThrottlingPolicy &quot;Increased ActiveSync Devices 
and 
Set-Mailbox $MAILBOX -ThrottlingPolicy &quot;Increased ActiveSync Devices 
 
(2) When I run Get-ThrottlingPolicy | fl EAS*, it show two sets of numbers - 10s and 20s as in DD: 42377319. 
Should I take further action? 
 
EASMaxConcurrency &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 10 
. 
. 
. 
EASMaxConcurrency &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : 20
</div>

<div>
You create new throtthling policy so when you get you have 2 of throttling 
And if you check mailbox get-mailbox |fl ThrottlingPolicy &nbsp; 
 
you'll see which one is affected to your mailbox. 
 
The difference between $MAILBOX and get-mailbox? it's just you not put anything in $MAILBOX; 
Normally with your command you should affect some mailbox to your variable like: 
$MAILBOX = get-mailbox (which one you want in policy)
</div>

<div>
@Jean-Re 
I am confused. When I run Get-ThrottlingPolicy | fl EAS* now, I get the following. 
Has maximum # of mobile devices per mailbox account been increased to 20? 
Am I all done here?

<div>
Do: Get-ThrottlingPolicy | fl Name, EASMaxDevices 
And 
Get-Mailbox | fl ThrottlingPolicy 
 
If you throttling policy with 20 device is correctly applied on mailbox it's OK, if not you need to set-mailbox to change the trhtteling

<div>
OK. It is good to know. 
Why Get-Mailbox | fl ThrottlingPolicy command kept repeating &quot;ThrottlingPolicy : Increased ActiveSync Devices&quot; as a result?
</div>

<div>
Because you get all your mailbox, do just a get-mailbox to understand what you are doing .
</div>

<div>
I see. Thank you for your help.

@Jean-Ré 
I am not sure if what we did is related to this or not, but I am seeing a bunch of Event ID : 36887 every second. 
When I did some research, one article seem to indicate that this could happen when there is a policy change. 
 
What do you think?

Hi, 
&nbsp; 
I have SBS2011/Exchange 2010. I saw this in an article that following Exchange Management Shell command will increase the default # of devices for an mailbox user &nbsp;from default value of 10 to 20.

With that I have questions: 
(1) Is that the right syntax/command? 
(2) How can I verify the current settings for everyone or for the organization for that matter? 
(3) Can I see this number in Exchange Management Console? 
 
Thanks.
