I am trying to verify a domain, that has it’s DNS managed by Cloudflare in Azure AD. I set the txt and/or MX records needed for verification as requested by MS. And the verification fails. When I dug into the issue, I discovered (by checking the DNS entries via MX toolbox) that TTL for those verification entries is set to 5 mins. I have manually set it to 1 hour (as requested by Azure) yet this setting seems to have no effect on actual DNS entries - they still show 5 minutes.
Anyone ever experienced something similar? Anyone knows how can I get the TTL to actually change?
