Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

This error is generated when I try to read emails from my mailbox. knowing that I am using aspose email version 22.5.

Hello @venturis,

Please provide a code sample and, if possible, a message file so that we can investigate your problem.

Here my code :

Dim client As IEWSClient = GetAsposeEWSClient()

 Private Function GetAsposeEWSClient() As IEWSClient
        System.Net.ServicePointManager.ServerCertificateValidationCallback = New 

        Dim mailboxURI As String = "*********"
        Dim username As String = "**********"
        Dim password As String = "********"
        Dim domain As String = "**********"
        Dim credential As NetworkCredential = New NetworkCredential(username, password, domain)
        Dim client As IEWSClient = EWSClient.GetEWSClient(mailboxURI , credential)

        Return client
 End Function

Here the exception :
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))


We tried to reproduce the problem on our side, but the exception did not reproduce. Can you check this with the latest version of Aspose.Email?
