Error: MAPI Error: (26) "Not supported"

[cbaqir]

Does anyone know what this error message means?

[#2]

can you supply some further inforamtion?  When do you encounter the error - I am guessing it is when you are setting up email?

Cassandra -

Is NPrinting set up to be a trusted app in the MAPI client? This is a requirement if using MAPI.

If you've already done this and still getting the error, please submit this issue to the Qlik Support Desk: Technical Product Support | Qlik

Cassansdra,

Just to add to what Stephen said, NPrinting supports simple MAPI but requires that a MAPI client (like Outlook) be installed on the local machine, and that the MAPI client "views" NPrinting as a trusted app. In Outlook 2013, you can set trusted apps in:

File>Options>Trust Center> Trust Center Settings>Programmatic access

NB that depending on the security settings in your company you may not have access to the Programmatic Access settings on your computer.
