Hi, Currently i have message size restriction to 10 MB for all Users to send to Internal and External users I wanted increase the message size restriction only for 100 users to 20 MB. I understand that i can in increase the message size restriction for individual users (Eg. below posershell command) and this will allow users to send Max of 20 MB size emails and it is only with in the orgnization. I cannot send 20 mb mail to outside as global limits take into effect. Set-Mailbox “User Name” -MaxSendSize 20mb Required solutions 1. Only 100 users should be able to send 20 MB email size to Internal and External users 2. Other users should not able to send more than 10 MB size email to internal and External users My Solultion 1. Increase MAX message send size to 20 MB for 100 users 2. Increase the send connectors Max message size to 20 MB With this there would be a transport config settings which would restrict all other users to send email to only 10 Mb and specific 100 users will be able to send 20 Mb size emails Does this solution works ? Kindly comment on this.. Regards, Krishna

I believe the Global limits apply to both internal and external email. You'll need to increase your global limit to 20MB as well. The Max Send Size on your internet mail connector will dictate the limits on what can be sent externally.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Hi Mjolinor, Setting send limits on individual users will override global limits.. Regards, Krishna

You cannot set the send limit on an individual user to a value greater than the Global limit. If your global limit is currently 10MB, and you want some users to be able to send 20MB, you will need to raise the Global imit to 20MB, and add individual limits for everyone you want to keep at 10MB.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Hi, I am sure this would be requirement for many people. To allow exception for 100 users i need to change the setting for 1000 users. if i have more users like 10000 then i dont think this would practically work out.. I am looking for atleast work aound solution, Your thoughts ? Regards, Krishna

Hi Krishna, I've set this up before. And I just want to give my thought. I had the question for size restrictions on mail for 3 levels and did set it up like this. 10 mb group1 20 mb group2 50 mb group3 So I created 3 transport rules with size restrictions like above. Group 1 had all users in it Group 2 selected users Group 3 selected users Now what is realy important? First match goes, so set up the transport rules in order of first group 3 than group 2 than group 1 Also remember that you have to increase global limits (send connector), database limits (and normaly users limits are restricted on db settings if not...) to the size limit of 50mb like group 3. So with those tranpsort rules you can keep controle of the size of messages. Also make sure you put the correct security on the groups for add/remove membership. I don't think there is anohter way to do this... If so I will be happy to hear it :-) And mjolinor is absolute correct about the globla limit. Another consideration is ps scripting the individual users for the settings. Scripting solves everything :-) but you still have to modify all the size limits on the other 2 places. Greetzz, Timmy

Timmy, i agree to your point. Thank you Mjolinor, Thank you I would like to see if any one else has some interesting work around solution.. I would be interested to see if Microsoft comes with some interesting option in the comming version of exchange or still we have run with some work around :) Regards, Krishna
