Exchange Hybrid Intermittently giving NDRs

so flag

New year, looks like a pretty active site. My company has a Hybrid config in place that cannot be removed at the moment. Since the 22/04 we have been having problems that certain domains intermittently fail with NDR. The NDR is due to a hop timeout as it seems to be bouncing between on-prem and Exchange. I have been speaking with other techs who say they have customers with similar problems since this date and I am checking to see if it's bigger than my problem. So hard to troubleshoot as it is intermittent. Thanks guys

Does the issue occur to internal users or external users? users on premise or users on exchange online?

Could you provide more details of NDRs for further troubleshooting? What is the specific generate sever for these NDR?

What can you see when you run get-messagetrace?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
