The "554 5.4.0" error is related with too many hops.
Were you sending emails to internal users? If send mails to this user directly from user1’s mailbox or user2’s , does the issue persist?
If possible , please provide a screenshot about the information in that NDR, it will help us to narrow down this issue.

It makes no difference if mail is sent to internal or external recipients. Problem persists.

Could you send messages successfully using OWA?
Please disable all Send connectors that you created yourself, and then use1 send the mail as user2 to your internal mailbox and see if there are any changes.

2022-07-26T11:00:16.54+00:00 Hi Andy
Permissions changes were done several days ago.
When we login as user1 and then 'open another mailbox' for user2 then user2 sent email fine in my test.
Regards
