PST (created with Aspose.NET) Import to Exchange online fails

We have 2 PST’s. PST1was created with an older version of the Aspose.Net for Email library, while PST2 was created with the latest version of the Aspose .NET library. When we import both these PST into Exchange online using the Data import job, PST1 succeeds, while PST2 fails.


You can please share the working sample code along with PST file reproducing the issue. We will be able to investigate the issue further on our end on provision of requested information.

We have done some further analysis and have identified this to be an issue due to DLL incompatibility. So this issue is now resolved. Thanks for your support.


It’s good to know things are resolved on your end. Please share with us if there is any further issue incurring on your end.
