How to disable the forward option in outlook rules.

Question

Our users are forwarding some emails to non-organization domains. Is there an option to disable the 'forward to' feature in Outlook rules or restrict forwarding to organization-controlled domains only? I know we can block this by creating a rule in the Exchange Admin Center, but are there any other options to achieve this?

Accepted Answer

No, there is no direct method to block this option, but as you've mentioned above, you can use the tenant-wide controls to prevent forwarding. Exchange Online now blocks external forwarding by default (read here for more details), and if you need additional control you can also use mail flow rules.

Hi，@Vishnu Anand

Thanks for posting your question in the Microsoft Q&A forum.

According to your description, you want to disable email forwarding to non-organizational domains. You can use PowerShell to create a remote domain and set the “AutoForwardEnabled” parameter to “$false”. This will prevent users from setting forwarding to the domain.

Run the following command to create a new remote domain (replace ExternalDomain.com with the domain you want to restrict):

 New-RemoteDomain -Name "NoAutoForward" -DomainName ExternalDomain.com

Then, disable auto-forwarding for this domain:

 Set-RemoteDomain -Identity "NoAutoForward" -AutoForwardEnabled $false

Remember to replace ExternalDomain.com with the actual domain you wish to restrict.
