PST Merge Behavior - Unexpected Message Count after Merge

I’m using the PersonalStorage.MergeWith(string[] storageFileNames) method in the 20.2.0 Aspose Email for .NET release.

I am attempting to merge 3 PSTs whose message counts are 32474, 31717, and 2332 messages respectively (66523 total messages). The merged PST has 66151 messages, which is short by 372 messages.

Is there a detailed description of the MergeWith behavior that might shed light on this discrepancy?


I have observed your requirements and like to share that generally it should not happen. Can you please try using Aspose.Email for .NET 20.3 on your end and in case there is still an issue then please share the working sample code along with source and generated files with us.
