Exchange 2013

Dear Experts,

Exchange 2013 standard  is installed in our environment. Created an Ou with the name Chicago. Around 50 users are in this OU.
I want  users in this Ou should send & receive mail to each others only. They can't send to other users in different OU.

Also in the address list they should only see their address that is there in their OU only.they can't view other mail ids.

Exchange is configured for internally only

How can I configure.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

the first part is easy
create a transport rule and specify the recipients - here is a good screenshot'ed guide

you can create a custom address list

not sure if that will hide all the others from them but you could make that the first option when configuring outlook

Just goto to user mailbox properties>mail flow settings>Message delivery restriction>Under Accept message from Click on "Only sender in following list". Add the required user. You need to repeat this for other 50 users also. This way user will accept message from those users only.

Hi Experts,

The above mentioned by Amit I have already done that settings. Now the users can receive the mails from only the authorised users only.  I need to make sending restrictions also. How can I ?

As i have already mentioned my main concern is about Chicago OU. I need to configure for this OU Only

I want this Ou users can't send mails to other users that is in FLORIDA, California, Philadelphia OU's users.

Please help me in configuring this sending restriction & also the address book for this particular ou i.e. Chicago

the best option is via the transport rules as i suggested
Add the users in Chicago into one distribution list
add the users in the other OU's into other distribution lists named accordingly.
You could take this one step further and create dynamic distribution lists which point to each OU so that when new users are created they will be added to the Dist List

create a Hub Transport rule which does't allow them to send to the other distribution groups.
If you set on the users mailbox then you will have to repeat for each user and everytime you create a new users (obviously you could script that) but using the transport rule then you can manage it centrally.

if you follow the first link it will stop them being able to do that
As an extra you can setup a mailbox which lets them know that they can't send a mail to them

Hi ,

All the above links is for Exchange 2010. Here we have Exchange 2013 in which settings are totally different from 2010.

the principles are the same between the 2 versions (at least for what i have suggested) the screen shots will be different but you should be able to get there
