Hybrid Exchange 2016 - SPF record not aligned
We have a Exchange 2016 Hybrid configuration. SPF and DKIM is setup. We use DMARC for monitoring only, not for rejecting. DKIM is 100%, but SPF is only 29% When spf verification is aligned we see ...
I take it you have listed your on-premises equipment in your SPF record even though you do not plan to send directly from it, and that you have then tested the SPF record with a third party such as Dmarcian?

If you are playing around with your DNS records directly, always test with a banked or minor domain before changing the principle records. Set your TTL as short as your provider will permit and monitor propagation with one of the global checkers as well as doing your own digs.
If you have to ask a third party to amend your DNS records, it might be worth asking them "what do you think?" Some will be able to help and others will cheerfully publish nonsense.
