Exchange Web Services - Admin Account but without License

Hi,

 

Is there a way to call the Exchange Web Services using an unlicensed Exchange Administrator account [unlicensedexchangeadmin@test.com] to list all public folders? 

 

Scenario: Listing Public Folders

1. Using the Exchange Admin Center with the unlicensed Exchange Administrator account, I can list the public folders.

2. Using the EWS.GetFolder with the same credentials, ErrorNonExistentMailbox was returned and no folders were listed.

 

Thanks,

Christle

Since the unlicensedexchangeadmin@test.com account doesn't have a license, adding it to the ApplicationImpersonation permission still returns ErrorNonExistentMailbox.
