I have this same problem running from source. I ended up uninstalling the NuGet package for HTMLAgilityPack on the MailBoxReader project and then installing it again (which installed an updated reference). So now I am running 1.4.6 instead of 1.4.0.
After this change I am now getting System.NullReferenceException: Object reference not set to an instance of an object.
at BugNET.MailboxReader.MailboxReader.SaveMailboxEntry(MailboxEntry entry)
at BugNET.MailboxReader.MailboxReader.ReadMail()
when the reader tries to read new mail.
Maybe it is related to the fact that the AjaxControlTookit contains "SanitizerProviders" one of which is HtmlAgilityPack 1.4.0 and which might cause some kind of referencing conflict. Any advice on how to get this working?
