Ouch! For the longest time it was only Alexa that could access my Workgroup (GSUITE) email and calendar info when Google Home itself still couldn't.
For real: For the longest time GSUITE account holders could not use a Google device, like a Google Mini, to play back their email or calendar information.
But, if you had an Alexa, you could. It really made no sense.
Eventually Google caught up with its own product line, and finally you could ask questions like "What's on my calendar today" or "What's in my inbox".
That the news now is that that Alexa will no longer access email or calendars for Google or Microsoft is ironic.
