I can help you regarding connectivity as I have successfully connected to many MSSQL data sources recently from Ataccama one. Let me know you want to connect to IDE or One and is the SQL server on same domain?

@PCapp Hello,  what type of errors are you receiving when attempting to connect to the MS SQL Data Source, as I might be able to assist as we successfully connected to this type of data sources.
