I've set up Google Workspace with SPF, DKIM, and DMARC, and they all check out fine on mxtoolbox.com. However, I'm noticing that some of the emails I send are ending up in the spam folders of clients using Microsoft. Has anyone else faced this issue? What can I do to improve my email deliverability?

Have you considered the content of your emails? Sometimes, tweaking the wording or modifying your email signature can help you avoid the spam folder. It’s worth a shot!
You've taken a solid step with SPF, DKIM, and DMARC, but they aren't foolproof. Even legitimate emails can end up in spam if they're sent from an IP with a bad reputation. While those protocols help, they don't guarantee delivery, especially if the service has strict filtering.
Exactly! Google has a pretty good reputation, so it’s puzzling that emails would still get blocked.
Microsoft's spam filters can be pretty aggressive. A lot of people run into this, even with proper authentication in place. It might just be a matter of their filters acting up.

True, but it seems weird that emails from Google would get flagged. Aren't their servers generally trusted?
