365 security roles and data protection
Which specific roles and/or permissions in a 365 tenant would allow the user, where granted, the ability to view: -all Mailbox content for all users/mailboxes, e.g. view the content of their inbox? ...
None of the default roles can access content within mailboxes, you need to specifically grant Full Access permissions for that, or use tools such as eDiscovery. For SPO, you will have access to the default site collection, but that can be adjusted as needed. If you need additional details, run a search online - this is a fairly common question and there are lots of articles discussing it.
