Outlook Rate limiting Cloudflare
I noticed outlook is blocking cloudflares SMTP server. I use MX records to outlook.
I saw on MS forums someone asked about the rate limit and Microsoft won't remove the block because Cloudflare themselves have to request the block be removed.
I use my email alias heavily and am locked out of accounts because of this.
Can cloudflare ask about removing the block? Or do I have to move the domain backing these email aliases to a different registrar / mail provider?

Just to confirm, you are using Cloudflare' Email Routing to forward emails to an Outlook account?
Yes that's right.
I did finally get the email in question, but it was hours later.
Cloudflare's router has been reporting this rate limit more and more frequently
This is very common with Outlook. Forward the emails somewhere else, or don't use Email Routing.
I had a feeling, thanks! I'll seek out a different email provider
