Since interactive user authentication to third-party systems is not possible
in processes, you need to log in to Microsoft Office 365 before
Microsoft Office 365 actions can be
initiated. For timer-controlled processes,
the user can be defined directly in the
timer properties.
Another option is the User switch action.
This makes it possible to switch to the Microsoft Office 365 service
user from within a process.
Select "OData/SAP Gateway" here, if you want to use the user switch action for
Microsoft Office 365.
