Hi Dror, Thanks for contacting Okta. Yes we do support Exchange and you can integrate it with Okta. However we do not have a specific documentation for it. In this case; I would suggest contacting your account executive to discuss and check possible Okta PS (Proffessional Services) team engagement. They are expertly suited to assist customers with this kind of integrations. Please feel free to create a case with us, if you require any further information or have any questions.
Thank you, Behrouz Ghorchi Level 2 Support Engineer | Okta inc.
