incoming/external email can not delivered to user mailbox

[counselor]

We are facing a strange issue, for some reason some incoming/external email from customer are not getting delivered in to user mailbox. I have gone through the message tracking center and i see below lines for some senders.

SMTP: Message Submitted to Advanced Queueing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Non Delivery Report (NDR) generated

Has anyone else faced the same? or has any idea about it??

Below is what i see in event viewer:

I have gone through the Microsoft link and it seems as if there is some email limit issue. Do you have any idea about this error??

According to the error you will have to set size limits for messages in Exchange Server. If you don't have any idea about it then you can refer to below article for the same.
