https://community.blueprism.com/t5/Product-Forum/sending-mail-failure-using-MS-Outlook-Email-VBO/m-p/75064#M27669 Hi Everyone, In my system, Even though that dll is configured, when I sent mail through MS Outlook Email VBO it throws an exception. I am attaching screenshot of that exception.  If I sent mail while outlook is opened or minimised then it didnt throw any exception. In my system, MS office 2010 installed. Do you have MS Outlook - without MAPIEx VBO ? If you have please share it with me. Thanks in advance.

I've worked with 2013 and 2016 without issue.
