Today our sports committee ask me that they want to send mail with their name (eg: sport_Committee@knights.com)

Rather then  creating a new user we can do this with distribution groups.
Here is what you need to do.
Note:
Distribution Group name                     : sports_committee@knights.com

Steps :

• Go to the Exchange management Shell and type the following command

Set-DistributionGroup 'Distrabution groupname' -GrantSendOnBehalfTo 'User' 

eg: Set-DistributionGroup Sports_Committee -GrantSendOnBehalfTo Thushara
