Exception while listing messages in inbox (ExchangeClient)

Aspose.Email Product Family

The ListMessages method throws the following error, probably because it doesn't like a particular message in the inbox. This stops the complete operation and doesn't allow any messages to be fetched. Pretty serious.....

2009-07-15 15:34:21.8122|Error|System.FormatException: The specified string is not in the form required for an e-mail address.

Could you please have a look at this issue.We're using version 4.7.1.0

Hi Bart,

It looks like some mail address parsing issue. Is there any chance you get the eml file to me? You can save them by calling the ExchangeClient.Save(string).

Thanks

Hi

To save the message I need the URL which I obtain from ListMessages, which fails.

I'll try to connect with Outlook and check if I see anything strange, but the inbox has hundreds of messages so it will be hard to find the one ListMessages is failing on...

Maybe something can be changed in the raised exception e.g add the url of the message it fails on??

Regards,

Bart

Hi Bart,

Could you please try to use the attached dll? Let me know if it works, or send me the exception.ToString.

Thank you very much.

Hi

Sorry for my late response.

This version of the DLL works fine, the exception is gone. Thank you.

Is this fix included in the latest 4.7.2 release?

Hi

Unfortunately it hit another exception with the same result; it cannot list the messages in the inbox although now the URL is included which helps a lot.

The message ‘from’ address is: “alert@notification.messagelabs.com [alert@notification.messagelabs.com]”

The exception is:

10:56:34 Error Aspose.Network.Mime.MimeException: Unknown errors in message parser.

Uri: http://…/Inbox/WARNING.%20Someone%20sent%20you%20a%20potential%20virus%20or%20unauthorised%20code.EML —> System.FormatException: The specified e-mail address is currently not supported.

Guys, now running 4.8 but still the same issue with some messages:

Aspose.Network.Mime.MimeException: Unknown errors in message parser. Uri: http://.../Postvak%20IN/No%20Subject-7.EML —> System.ArgumentException: The parameter ‘addresses’ cannot be an empty string.

All I can do is delete the message, otherwise I can no longer list messages in the inbox … not good.

Please help

Regards

Hello,

Could you please send me the eml file for the investigation? Looks like some address fields are missed in the eml file.

Thanks,

Sorry, have no EML, had to delete the message immediately to restore production. By the way, Outloook Web interface had no problem with the message.

I had similar problems with ExchangeClient.ListMessages and it can be quite a big problem if everything stops because of one message that can’t be parsed. Someone has to search for the message and remove it… you can imagine that in a critical production environment with potentially thousands of messages this a disaster.
It seems like we need a better ListMessages method that is more resilient to the errors on a single message level. It definitevely shouldn’t just throw an exception and stop.

cheers
