Looking for assistance to stop my email from being blocked by spamcop to a single client.

I do have additional message header information

Did you follow the link? and see the email was blocked because:

Quote

(your email) System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

Also notice that: If there are no reports of ongoing objectionable email from this system it (your IP) will be delisted automatically in approximately 7 hours.

To your request, generally there are two possible causes for the IP address used by your email service being listed on SCBL: 1) Your email list includes addresses scraped from the internet that point to spam traps, or 2) your email service shares an IP address with another users who have sent emails to spam traps.

Based on your post, your client uses an email service which uses SCBL to filter their incoming email. If your client wishes to receive your email in spite of being listed as a source of spam, they may be able to white list the IP address used by your email service.

It is strongly suggested that you scrub your email list to assure only double-opt-in email addresses are included. After assuring you are not sending spam talk to your ISP to avoid sharing an out going IP with others who do send spam.

Causes of listing
System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)
SpamCop users have reported system as a source of spam less than 10 times in the past week

Microsoft is giving free trials for Microsoft365 
Not sure if its spammers using it or naïve beginners learning email marketing?
There are numerous "spam traps" out there, SpamCop is the only one  that allows one to know its blocked until the spam flood stops.
Most Major email providers have their own blocklists generated by placing poisoned email address's on websites, newsgroups, etc.
Poisoned email address are obtained/gathered by web BOT's called web spiders scraping off email addresses!
They just don't tell you, you are blocked, Bit-Binning or spam bucketing them instead.
Don't buy email addresses, learn about double opt-in (MailChimp) and create your own!

I love reading all about the spam  and prevention techniques. (I'm a geek) We work hard to implement and monitor our email delivery i.e. dkim,sft, delivery reports. and if we were to do any email at scale I would probably setup a subdomain for my campaigns so as to not effect the primary domain rank and primary intake email delivery . but in this case it's our main intake email only that's flagged by spancop. that's what has me puzzled.

Thanks for the input.

This is up from 7 hrs shortly after your first post. This means the IP continues to send email to spam traps. No one here can help you fix that.

If you do not have a dedicated IP for your outgoing email, that is between you and your ISP.

As Lking suggest you are using a Microsoft shared IP for Office365 a spam-trap should not ever confirm or deny that it is being hit!
SpamCop AFAIK is the only one that does the vast number of others will not, So it will not be listed only by SpamCop.
SpamCop only blocks for 24 hours after spam stops hitting SCBL, the others probably bit-bin after tripped for weeks if not months.
You need to make sure your email list is not full of poisoned/spam-trap email addresses.
But even if your email address is clean, does not mean others using Office365 shared IP's are
Ideally you need to send from a dedicated IP
