HOW TO LOCATE missing incoming emails?

Hi,
Emails are not coming in to a specific mailbox.
I have a generic user called accounting and I see no new email in it after november 16th.
I have Exchange 2016 and not used to it. also all my email are first sent to ProofPoint then to my Exchange.
The logs on proofpoint tells me that they were delivered.
I don't know where to lock for them in Exchange 2016.
I tried going in MAIL FLOW - MESSAGE TRACE and then In the box " mailbox to search " entered  "accounting" and in the 2nd box "seach message send to " I reentered "accounting"... no result

If possible, only search one thing at a time. Search just for mail sent to the account address (including the domain name).

Also check in the email client (Outlook) and make sure there are no filters turned on. Send an outgoing message from accounting to yourself and then reply back. That way you know for sure there was a message. Also, this message will be internal, so the ProofPoint won't be involved.

Just a guess, is this mailbox managed at all? Is there any chance it is full?
If the mailbox is full, delivery does not happen with an according error message sent to the transmittting MTA (ProofPoint). Since they say it has been delivered, it has been confirmed by Exchange.
i would search the trace using the time period of the ProofPoint log to see details.
