We are already using "Redemption.dll"(http://www.dimastr.com/redemption/home.htm) in one application developed in VB.Net. Now we need to use Redemption to create PST file for Linux environment.
So, can we use Redemption in .Net Core (https://en.wikipedia.org/wiki/.NET_Core) application or with JAVA?
No, Redemption depends on the MAPI system to be present. The MAPI system is only installed by Outlook. You can also install the standalone version of MAPI, but it is no longer supported by MS. Windows is required in both cases of course.
