Hello Everyone,
I have a few questions regarding External User Access to On‑Prem Exchange via Netskope Private Access or Reverse Proxy.

We are using Netskope Private Access (NPA) to publish our on‑premises Exchange Server behind a Netskope Publisher. Currently, only managed devices with the Netskope Client are allowed to access OWA and Outlook, and unmanaged devices are blocked who don’t have Netskope agent Installed — this is working as expected.

This behavior is working as designed and aligns with our Zero Trust access policies.

We now have a requirement to allow external users to access Outlook or OWA from non-managed devices and we have not exposed our OVA to Internet.

Could you please confirm the following:

  1. Can Outlook or OWA access for external users be provided using Netskope Private Access without requiring the Netskope client on the user device?

  2. is there any other supported approach  to provide external user access to an on-premises Exchange server?

Thank you for your confirmation.
