We are actively working on making it generally available and will update the status as soon as it is done.Brian supported this idea ·Brian commented
I would like to add my support to this idea. Our company staff have 2 email addresses each. The primary is the directly attached to the user log in and all add ins work with this email address / account. However when the staff member opens their other email address as a shared mailbox none of the add ins are available. So at the moment we have templates on the primary email address but not on the shared mailbox.
Having the add ins work on shared mailboxes and folders would be of great use to us.
