Get Exchange Mail Messages - Activity: One or more errors occurred

Help

Hello,

i discovered a reproduceable bug in the “Get Exchange Mail Messages” - Activity:

When a mail is sent to an non existing receiver, an automatically mail is created by the exchange server that informs about a failed delivery. With THIS mail in the Inbox folder, the acitivty is unable to load mails.
I configured the activity for a “SharedMailBox”.

Can anyone help or confirm the bug?

The following error occurs:
Get Exchange Mail Messages:
One or more errors occurred.

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:

I got this error when I passed the folder name. Then what I observed was there were problems with depended packages. Once I fixed all depended packages it started working properly.

Make sure all depended upon packages are available in development as well as in production
