Enabling Remote Mailbox in Exchange (On-Prem)- Custom action - Flow Designer

[Danelle Lee]

Hi all,

I have a requirement to set up a custom action to enable a Remote mailbox through Exchange on-Prem.

Ideally, I would like to connect to the server using a credential alias. 

I've tried testing this quite a few times and have been unsuccessful so far. Wondered if anyone else has succeeded in doing this?

I have attached my inputs and script details etc.

Thank you.
