Exchange internal users attachment size restrictions

hi Experts,

We have a Exchange server 2010. We want to restrict the attachment size of internal users. External users it is 20 MB, but for internal users I want to restrict it to 3 MB.
Is it possible, if so how?

Thanks your help in advance

In Organization Configuration -> Hub Transport -> Global Settings -> Transport Settings, set "Maximum send size" to 3072 KB.

Muhammad Burhan,
I don't think there is a option in Transport. When you create the rule, you select from 'inside the organization'. in Action you dont have attachment option.

Sorry I have to edit my question. Internal emails i.e. communication between internal users should have a restriction of 3 MB and external emails should be 20 MB i.e. Internal to External emails. and External and Internal emails

In Transport rule you can block emails under  a particular size i.e. I can block emails over 3MB but not the other way around.

Muhammad Burhan,

1) In conditions you select Inside Organization
2) In actions you are asking to send bounce messages, but where is the condition. If I do that it will send rejection message to all users.

Thanks Muhammad. It worked. Setup rule as per below
Setup a transport rule from users internal users, sent user internal users, attachment size limit 3mb and error reference 5.7.666.
