How to increase the maximum number of ActiveSync Devices for a User

sglee

on
Hi,
 
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  from default value of 10 to 20.

New-Throttlingpolicy "Increased ActiveSync Devices" -EasMaxDevices 20 -EasMaxConcurrency 20              Set-Mailbox USER_MAILBOX -ThrottlingPolicy "Increased ActiveSync Devices"

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.

Hi,

You can see on the present policy:

How do I set max number of devices for all mailboxes to 20?

I searched and found this command:

New-Throttlingpolicy "Increased ActiveSync Devices" -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           : 10
EASPercentTimeInAD          :
EASPercentTimeInCAS         :
EASPercentTimeInMailboxRPC  :
EASMaxDevices               : 10

I tried to apply the policy by running:
Set-Mailbox $MAILBOX -ThrottlingPolicy "Increased ActiveSync Devices"

But this generated an error:

Cannot bind argument to parameter 'Identity' because it is null.

Yes it's correct, but your $MAILBOX seems to be empty
YOu can do  Get-Mailbox -RecipientTypeDetails UserMailbox | set-mailbox -ThrottlingPolicy "Increased ActiveSync Devices"  
to impact all usermailbox on your server.

When I ran - Get-Mailbox -RecipientTypeDetails UserMailbox | set-mailbox -ThrottlingPolicy "Increased ActiveSync Devices", it went successfully.

(1) What is the difference between:
Get-Mailbox -RecipientTypeDetails UserMailbox | set-mailbox -ThrottlingPolicy "Increased ActiveSync Devices
and
Set-Mailbox $MAILBOX -ThrottlingPolicy "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           : 10
.
.
.
EASMaxConcurrency           : 20

You create new throtthling policy so when you get you have 2 of throttling
And if you check mailbox get-mailbox |fl ThrottlingPolicy  

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)

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?

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

OK so it's good

Commented:
OK. It is good to know.
Why Get-Mailbox | fl ThrottlingPolicy command kept repeating "ThrottlingPolicy : Increased ActiveSync Devices" as a result?

Commented:
Because you get all your mailbox, do just a get-mailbox to understand what you are doing .

I see. Thank you for your help.

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?
