Location of OST in the Namespaces

I can locate PST in the Aspose namespaces but not OST. Might someone oblige please by pointing to where OST is located in the namespaces? Regards, Sean

Hi Sean,

Thank you for contacting Aspose Support team.

The API doesn’t have any OST class or namespace in the API and the same PST can be used to read the information of an OST file. Please use the PersonalStorage.FromFile(“ostFile.ost”) to read the OST file using the PST class. Once the file is read in, you can use the same code of traversing, parsing and extracting messages from the OST files as you used for the PST file. Please let us know if we can be of any additional help to you in this regard.

Thank you Kashif. I have tried that but an error is thrown, “The file is not in PST format”. I am using Visual Studio 2013 and Outlook 2016. Any clues please? Kind regards, Sean

Hi Sean,


Currently Aspose.Email does not support OST files from Outlook 2013 and 2016 as no open specifications are available. We are currently working on OST file Outlook 2013, and will move to next version later.

I am sorry for any inconvenience caused to you in this regard.
