Apose.Email fails on FetchMessage for some mails

Hi Aspose,

The error occurs on Exchange 2012 SP3, when fetching an untouched message.
Once the message manually has been moved or touched on the Exchange server, the error disappears.

System.FormatException: An invalid character was found in header value.
   at Aspose.Email.Mime.HeaderCollection.Add(String name, String value)
   at __._Ÿ•.FetchMessage(String )
   at eTrayMailService.EmailUtilities.AsposeClients.ClientWrappers.NewEwsClientWrapper.FetchMessage(String uniqueId)

We are using Apose.Email 5.0

The attached MSG-file cannot be used to preproduce the problem, beacuse it has been touched when we retrieved it from the Exchange server.

Do you know about this problem?

With regards
