Have the SaveAs and ConvertTo functions been implemented for OST files created in OL’2013/'2016?
Have tried .ost files from various types of email accounts
Outlook.com using EAS
Generic IMAP account
Microsoft Hosted EX account
and all return either of following errors - not really consistent
{“Header CRC is not valid !”} or
{“The method or operation is not implemented.”}
One thing that I noticed that every time I try to run either of the two functions on the <[onmicrosoft.com](http://onmicrosoft.com/)> EX account - the .ost gets corrupted when I open Outlook again - have to delete it and let Outlook recreate it.
System specs - W10 Ent Ed / OL’2016 Pro Plus (.msi) / VS 2015 Ent Ed / Aspose Email 6.2.0.0 / .Net Framwork 4 Client Profile - Outlook always closed when running any test
Sample Code used to test the Convert/ToSaveTo functions
Import Aspose.Email.Outlook.PST
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim pst = PersonalStorage.FromFile(“c:\users\karl\appdata\local\microsoft\outlook\cgsupport@outlook.com.ost”)
pst.ConvertTo(FileFormat.Pst)
End Sub
*** when trying the SaveTo function - I did include the output file name
