Exchange 2013, 2016 not allow some users to send or receive (POP3) emails when they are outside of the office (access from internet)

Hello, we want to know how to set Exchange Server 2013/2016 to restrict some users send / receive (POP3) email when they are not in the office (from internet).

We only allow them to send/receive (POP3) emails in the office (intranet).

Hello,
I have an idea to test this. I don't have a mailbox available to test it from my side. Here is the way

  1. Connect Exchange Online using PowerShell

  2. Get-CASMailbox 'mailbox name'. Preferably select a test mailbox

  3. Check the property 'ExternalPopSettings' value. In an environment with POP enabled, this value will show you the server name

  4. Set this value as False for a test mailbox. Set-CASMailbox 'Mailbox Name' -ExternalPopSettings $Null

  5. Check if you are able to disable the external access for this test mailbox. Also, restart the POP services to confirm

If it doesn't work, I am sure that there is no way you can selectively disable/enable external Pop access for selected mailboxes and the settings applied to organization wide

Regards,
Manu

Thanks Manu, I can't find ExternalPopSettings parameter for Set-CASMailbox after testing and checking Exchange Documents.

Thank you very much.

Hi,
This settings can't be found in Set-CASMailbox as you mentioned. But this is there in Get-CASMailbox cmdlet. What I conclude is the requirement can't be done as per my belief

Thanks,
Manu
