Exchange 2019 Full Access to all mailboxes

These steps were performed but doesn't seem to allow it to see all mailboxes: The odd thing is those steps did work on the first iteration of Server 2019 and 2019 Exchange but I think an update may have broken it. Hence the quest for official docs that say the correct procedure preferably from MS.

Hope this helps you

To do that with PowerShell, use this cmdlet:

Get-RoleGroup "Organization Management" | select members

In case the given account is not a part of Organization Management group, the administrator needs to change that using this cmdlet:

Add-RoleGroupMember "Organization Management" -Member "<account name>"

<account name> should stand for the name of the desired user.

The next step is granting full access permissions to mailboxes:

Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'UserMailbox') -and (Alias -ne 'Admin')} | Add-MailboxPermission -User admin@example.com -AccessRights fullaccess -InheritanceType all -AutoMapping:$false

This will grant full access rights to all users for the account “admin@example.com”. The last parameter, “‑AutoMapping:$false” is not necessary, but is worth considering. It enables you to turn the Auto-mapping feature off. By default, if you do not include the parameter at all, it is set to $true. If it is not deactivated, admin’s Outlook will try to open all mailboxes in the company. This is rarely desirable and in case there are a lot of mailboxes, performance issues are to be expected. What is more, in many scenarios, users have experienced that removing Auto-mapping later on might prove to be problematic. Remember that if you do not include

The Get-RoleGroup and Add-RoleGroupMember have been ran and ran successfully. I'm confused a little bit on the last larger query. Could you not just run the Add-MailboxPermission side by itself? Is the filtering needed at that point? Maybe I'm thinking about it incorrectly.
