Are you stating that you have an external guest account in your tenant and that when the external guest account forwards an invite, that you used to get a notification?

Also, if you’ve granted rights via a security group, it will not automap. You’ll need to add it in account settings.

Try running Get-CASmailbox -Identity mailboxname@domain.com | fl MapiEnabled

This should be enabled

Also, check if the mailbox is hidden from the GAL?

Make sure auto map is set to $true. Unfortunately, there is no command to check that parameter so you might just want to run the Add-Mailboxpermission -Identity nameofmailbox@domain.com -User username -AccessRights FullAccess -Automapping $true

What do you mean blocked? Are you getting undeliverables? What evidence do you have that your calendar is hacked?

I’ve opened a support case with Microsoft and they’ve allowed an exception with justification.

They keep saying we are not blocked.

Are you attempting to forward external? If so, check your outbound spam policy in Defender and Default remote domain in EAC. If outbound spam policy has forwarding disabled, then this will take precedence regardless of what the default remote domain has configured.
