Hi team,

Need your help in some external identities scenarios. My main goal is to check if I can have a unified address book between different office 365 tenants. for that i have the below questions:

  1. If i'm my organization external address are set to allow anyone to invite guest users from other organizations. Then guest users will be created in my azure ad so is this means that they will be also available in my exchange online address book?
  2. if i'm using crosse tenant settings and azure ad collaboration and i have added my partner organization and allowed inbound access. will this mean that any user will be able to have access to my source AD and the users will be created in my azure ad as guest users automatically or will i have to invite them oncea again as guest users? and in both ways, will they be available in my address book
  3. for direct connect i checked that the users won;t be added as guest users in my AD and it works for team channels. Is it just restricted to teams? or these users can be added to my M365 groups or M365 apps as well? and again what will happen in my address book after setting up direct connect.

many thanks
