On the latest message+, ver 2.0.2.0 on Windows 10, the contact manager seems to have disappeared, Trying to add a contact gets me that I need to look for an app in the store. I tried using the generally terrible Microsoft People and it's useless. There's a perfectly good contacts portion of outlook that seems to be ignored by message+, and yes, I checked default apps - there is no default setting for contacts management, and outlookis se as my email default.
How do I manage my message+ contacts on Windows?
