Hi,

We are running Exchange 2013 SP1 CU5. We would like to restrict users from opening Other Mailbox from OWA. I create a new OWA Mailbox Policy and set ExplicitLogonEnabled to false and apply the policy to the some users. Wait 24 hours, restarted Exchange Servers but users can still use the Open other Mailbox Feature in OWA?

Is there a possibility to disable the permission option in OWA. i.e. Restrict users from configuring delegated permission on their mailbox from OWA?

Regards,

Hi Irfan,

Please run following commands:

Set-OwaVirtualDirectory -Identity "Contoso\owa (default Web site)" -ExplicitLogonEnabled $False

Set-OwaMailboxPolicy -Identity "Contoso\owa (default Web site)" -ExplicitLogonEnabled $False

Thanks

Hi Irfan,

Please run following commands:

Set-OwaVirtualDirectory -Identity "Contoso\owa (default Web site)" -ExplicitLogonEnabled $False

Set-OwaMailboxPolicy -Identity "Contoso\owa (default Web site)" -ExplicitLogonEnabled $False

Update: Thanks for the notification, the command should be Set-OwaMailboxPolicy -Identity Default

Thanks

This one fails as I have no OWA Policy with this name Set-OwaMailboxPolicy -Identity "Domain\owa (default Web site)" -ExplicitLogonEnabled $False.

I use Set-OwaMailboxPolicy -Identity Default -ExplicitLogonEnabled $False.

But still doesn't work.

Hi,

We should apply the OWA policy using Set-CASmailbox Cmdlet. It does not apply by default.

Please use below CMdlet and apply the policy to required users.

set-casmailbox -Identity Username -Owamailboxpolicy Default

The Default Policy is already applied on the user.

I am currently installing CU8 to see if it resolve the issue.
