Disable OWA for All Users Except One Group


Our company wants to disable OWA for all users except the users in the "Managers" AD security group. I came up with this script below but wanted to know if there was a better way. Also from my searches, there is still no way to make OWA disabled for new users by default?

Thank you.

AD level 2003 on 2008R2 DC's
Exchange 2010 SP3

Get-Module -ListAvailable | Import-Module

get-mailbox -OrganizationalUnit "OU=Users,DC=MyDomain,DC=com" | Set-CasMailbox -OWAEnabled $False

Get-ADGroup -filter {name -like 'Managers'} | Get-ADGroupMember -Recursive | Get-ADUser -Properties MailNickName | select -ExpandProperty MailNickName | Set-CasMailbox -OWAEnabled $true

I think you can use your webfilter like Fortinet to do it

Your scripts are going to be the best way to handle this.  You can also schedule them to run so you dont forget when there are new employees added

Thank you. I just wanted to make sure I wasn't missing something. The script has been added to the Exchange maintenance script.

Souf, we did not want to block it for all users, just a certain group.
