Hi Haseeb,

Thank you for writing to Aspose support team.

I have investigated this issue at my end using the latest version of Aspose.Email for .NET 4.8.0 and was not able to observe the mentioned problem at my end. Appointments are listed fine from the Calendar folder. The tests were carried out with Exchange Server 2010. Could you please share if you are using this latest version of Aspose.Email? Your feedback will help us assist youf ruther in this regard.

Hi Kashif,

I have updated to version 4.8.00 and exactly it is the same error with 4.8 as well.

Can you please share your code.
