we have an enterprises application in azure ad and by default users from my Azure ad account authenticated but now I want one of my partner who uses okta but not azure, wants to access my application which is in azure under enterprises application and authentication must be using okta credentials.
how to provide access or integrate users from okta to azure ad ?

Hi @mohanR.92529 (Customer) , Thank you for reaching out to the Okta Community!
If I understood your use-case correctly, if the users must use the Okta credentials, you'll have to set up Okta as the IDP (Identity Provider) for Azure AD.
You might be able to achieve this through WS-Federation via the Microsoft Office 365 integration with Okta, as the user accounts from the domain Provisioned to O365 should be automatically residing within the Azure AD domain. Hence, if a user tries to sign into a Microsoft resource via https://login.microsoftonline.com/ they should be redirected to Okta for authentication due to the domain federation.
That being said, the implementation is complex and I do not recommend attempting it in production until you've successfully tested the proof of concept in a preview/demo environment.
Also to note, that WS-Federation is a "all-or-nothing" type of implementation in the sense that all users from the federated domain will be redirected for authentication to Okta, regardless of their use case, roles, licenses etc... For example automated service accounts might lose access to resources due to the requirement of having to go to Okta to authentication.
Here is the source documentation to help you get started:
