Read and Convert Outlook OST File
Aspose.Email provides an API for reading Microsoft Outlook OST files. You can load an OST file into an instance of PersonalStorage class and get the information about its contents, for example, folders and subfolders.
Reading OST Files
Reading an OST file with Aspose.Email is exactly similar to reading a PST file. The same code can read both PST and OST files: just provide the correct file name to the PersonalStorage.fromFile() method.
Converting OST to PST
Aspose.Email makes it possible to convert an OST file to PST with a single line of code. Similarly, the OST file can be created from the PST file using the same line of code with the FileFormat enumerator.
