Outlook Add-In displays Error: "Insufficient attachment permissions"

1

Hi everyone,

i locally installed the Outlook Plugin according to the manual.

When adding an Email to a Workflow instance, i get an error "Insufficient attachment permissions" (see screenshot).

I have to admit, that i used the Edge browser instead of Internet Explorer to install the add-in.

What could i do to fix this?

Thanks for considering my request,

Christian
