I'm trying to use the "Create appointment" workflow action with the credentials from a service account that has full admin permissions in Exchange 2013, but I still get the following error when my workflow runs:
Error occurance:
True
===========
Error text:
Task item failed with response code ErrorFolderNotFound
Does anybody know the specific permissions I need to give my service account in Exchange in order for it to be able to create appointments on any user's calendar?
