Hi,
HAREDIRECTFAIL would not cause a message missing, would you post the whole result of message tracking log here? Don't forget to cover personal info.
Did the sender receive any NDR message?

Then this is expected with one server and can be ignored
HAREDIRECTFAIL is used for shadow copies

https://learn.microsoft.com/en-us/exchange/mail-flow/transport-high-availability/shadow-redundancy?view=exchserver-2019

You can disable if you want if using only one server:

https://learn.microsoft.com/en-us/exchange/mail-flow/transport-high-availability/shadow-redundancy?view=exchserver-2019#shadow-redundancy-is-enabled-by-default

Set-TransportConfig -ShadowRedundancyEnabled:$false
