Outlook Redemption component - Invalid number of arguments

I am testing the Redemption library for a small project to purge emails from PST files. The below simple code with Redemption library to open a PST file should supposedly run fine, but gives an error:

RDOSession pstSession = new RDOSession();
RDOPstStore store = pstSession.LogonPstStore(@"d:\1.pst");

I get an error - "No overload for method 'LogonPstStore' takes '1' arguments".

As per the docs here, there is only 1 mandatory parameter for LogonPSTStore(). So this error is confusing..

I am using the latest version of the Redemption library with Outlook 2016. Any help would be appreciated.

Solution

  • Newer versions of .Net do not make you specify optional parameters in COM methods. VB/VBA always did that.
    You can pass Missing.Value for the optional parameters.
