[EWS] Access hybrid public folders with EWS RRS feed

  • Question

  • Our customer has a hybrid Scenario with Exchange on premise Hosting public Folders and O365 having the users, similar to the Scenario here:

    In our app we have the O365 user configured, but when we try to Access public Folders using EWS the Reply is "There are no public folder servers available"

    Would we have to retrieve the public Folder address via Autodisover from the PublicFolderInformation tag from O365 and use the same user credentials to Access the public Folders on this second Server?
    Or would we have to configure a second account with its own user credentials to Access this?

    Let's assume I am just using SoapUI or a similar EWS tool and have the O365 user account, how can i Access the public Folder?
