I wouldn’t be sure that anyone in SalesAgility is going to be looking at this any time soon. My guess is that they will do so if pushed by one of their clients, if not, they will focus one of the other 1000 things on their work list. Fair enough.
This is the sort of thing that the Community can solve, people need to get together and try to find ways to make this work with tweaks to the existing code.
I wouldn’t think of this in terms of a “Connector”, or any fancy new functionality, I would just focus on the hurdle of getting OAUTH2 authentication to work. SuiteCRM uses something called PhpMailer, we probably need to add a special case in there at the moment it’s authenticating. Perhaps this will require some additional field on screen, in the UI. But it shouldn’t be terribly difficult.
People can get together and pay a developer for a few hours of work cracking this problem [not me, I’m not free at the moment].
