is it possible to get access to mails of a specific user account (Exchange Server /Outlook 365) via KNIME,
to search the emails for a keyword for example “Bestellung” & “Order” ?
My first attempt to read in *.msg files, saved in a special folder, via the Tika parser node worked.
Question 2: Is there a way to connect KNIME directly?
GET Request node is one which sends a HTTP request (so not a node for establishing an open connection if that is what you think you have done). It is used to retrieve data from a web service. Result (data) you get depends on request you have send. To get data you want you should study API definition and send proper request. Still you will probably need additional nodes to manipulate data to get it in format you need.
Unfortunately I don’t have Exchange Server to give it a try.
