OST larger than 51GB cannot be opened

Aspose.Email Product Family

When accessing an .OST larger than 51GB Aspose.Email is throwing an exception.

Dim ost1 As PersonalStorage
ost1 = PersonalStorage.FromFile(filename, False)

Exception: "Destination array is not long enough to copy all the items in the collection. Check array index and length."

Is there a known limitation for .OST containers?

Thank you.

Hi Jeff,


Yes, there is a known limitation on the size of OST as can be seen from here as well: File size limits of .pst and .ost files are larger - Outlook | Microsoft Learn. This shows that the maximum size can be 50 GB for Outlook 2010 and 2013.
