This is a tricky situation; I don't know if we can do anything here. I mean, AAS requires a mail contact / mail user object from what I remember. And when the Google Workspace Migration is started, yes, the MEU gets converted to Mailbox. This means that F/B from EXO mailbox to EXO mailbox will be internal. Maybe to create MEUs/ Mail Contacts with the Google subdomain, an AAS for that subdomain and then the EXO user to know which one to pick in the free/busy request, but that is way too complicated workaround for a few days until the user is migrated to EXO and calendar items synced fully. I can still ask Engineering folks to see if something can be done in this regard.
Maybe from Google side, if there is any setting to share calendar items from there meanwhile users are being migrated? I don't have much experience with Google workspace migrations / integrations, unfortunately. Thank you for pointing this out.
