Are the sent access requests stored somewhere? In our setup, the site owners do not have full control rights. The access requests go into their mailbox, when approved, they forward them to the admin team, who can actually grant the access rights.
Are the original access request stored in a list, so we can track somehow make a connection between our mailbox and this list and keep the status of the access requests?
Update: The Access requests and invitations option is missing from the options under Site Permissions on site settings. On some of the sites, we have access requests disabled (also on the top site of the site collection), can this be the reason why I am missing this possibility?
