Is there any way to link Office365 contact details in mobile with Zoom app in mobile?

Seems like zoom only can acess the contact only in the mobile , not Office 365.

Cause sometime I need to arrange the meeting via mobile and need the email address details from Office365 app.

I recently started taking online classes and in the last few sessions, everyone else can see the hosts screen when he starts sharing except me, all I see is a black screen but I can actually see his mouse cursor moving around the screen but nothing else

I only have access to using one device which is my android phone and I've torn through every setting, tried reinstalling the app but nothing changes, please help me

I am selling a spare Poly CCX500 to a friend who wants to have a zoom phone. When I remove it from my account in the settings I get a message that "plugging it back in will re-add it to your account" Does that mean when my friend goes to set it up he will get the "this phone is already registered to another user, you must send pictures of the phone in your possession to support"? Is there a way to avoid that safety dance? I haven't been overwhelmed thus far by Zoom support customer service"

Thank you,

Seth
