I have sharepoint 2016 in azure cloud (installed on VM in the cloud). I have 2 custom lists in the same site collection - list A and list B with the same collumns. I need to sync any changes on items (added, deleted, updated) made in list A to list B. Is there any OOTB solution (also interested on SP2019)? So far i checked:
MS Flow - i have account to Office365, can start to build Flow but it says the site collection is not available (although it's reachable on public internet)... how can i use the ms flow?
I may implement a small app in C# using CSOM and schedule to perform sync lets say every 5 min. Or maybe create event handlers - how can I deploy them to the server?
any other idea? use SP Designer 2013 to create workflows
