Anyone using Node-Red in combination with Office365 ?

yes, node-red was initiated by ibm, but it is driven by a nice community :)

if you compare the amount of triggers within node-red with the "175 triggers" MS flow offers at the moment, then i would say that the open community of node-red offers much more

https://flows.nodered.org/

the main target group for MS Flow (in my opinion) are the Endusers

-->if there is a new file on onedrive, then do whatever)

..whereas with Node-red you have plenty of things for system people (and all the folks who are interested in this IoT topic)

one example:

there is no ms flow thingie available for Apache Kafka. Kafka is in my case one key element which i use to re-route all differnt things (and to use it in combination with node-red).

If you miss a "Node", then just develope it yourself....

there are for sure dozens/hundreds of other usecases.

as said, MS Flow is cool stuff...but just targeting endusers which is in my case the wrong group of people.
