“Not implemented” error occurs when converting OST to PST

When I execute the following code :
Try
If File.Exists(OutFilename) Then File.Delete(OutFilename)

		Using ost As PersonalStorage = PersonalStorage.FromFile(Infilename)
			ost.SaveAs(OutFilename, FileFormat.Pst)
		End Using
	Catch ex As Exception
		Stop
		Console.WriteLine(ex.Message)
	End Try

I get this error : “The method or operation is not implemented.”
Why

@elumicor

Can you please share the OST file that is having issue on your end.

Sorry, it is my company’s.
I found other documentation that stated this function does not work for 2013-2016 outlook. The company is running 2019 outlook/exchange sever.

I am sorry, without provision of source OST, how we may reproduce and investigate the issue on our end. Can you make some test OST that reproduces the issue on your end and that we may use.

@elumicor,
Please use the latest version of Aspose.Email.
