Hi All, in my organization, when I want to create new mailbox (existing / new), I want to disable OWA feature by default. Any ideas ?

There is no way to automatically disable owa for new mailboxes, this must be set after the mailbox is created. Thiere ight be some third party tolls you can use that does this for you but if you are using just Exchange you will have to administrate this manually after the creation.

There is no way to automatically disable owa for new mailboxes, this must be set after the mailbox is created. You can do this using powershell, create a small script and add the script as a scheduled task that runs every night. If you want to have OWA enabled on some mailboxes you can, for example, add a custom attribute to those users. Then disable all users that do not have the custom attribute. To disable owa for all users run the following command: Get-Mailbox | Set-CASMailbox -OWAEnabled:$false To disable owa for all users that do not have a custom attribute (in this example, CustomAttribute10 set to EnableOWA): Get-Mailbox | Where {$_.CustomAttribute10 -ne "EnableOWA"} | Set-CASMailbox -OWAEnabled:$false Thiere might be some third party tools you can use that does this for you but if you are using just Exchange you will have to administrate this manually after the creation or using a simliar script.
