Restrict User Log on to Multiple OWA Urls based on OU filter

Hi All,

Good Day!!!,

Scenario

2 AD Servers

2 Exchange Server 2013 (CAS + Mailbox)

2 Separate OU in AD ( OU=itquery.in & OU=technosavee.com)

We have two OWA page

    https://mail.itquery.in

    https://mail.technosavee.com

Our query is users are created in Itquery OU should not login into their mailbox usinghttps://mail.tecnosavee.com.

Since both users and mailbox are in same domain vice versa they can able to login.

We need to restrict itquery.in OU users should login using onlyhttps://mail.itquery.in

                                    technosavee.com OU users should login using only https://mail.technosavee.com

Any solution will be helpful and appreciated.

Thanks

Thanks & Regards, Kesa_Kara
