Own domain flagged as harmful by Safe Links — submissions return "Unknown"
Our organization's own domain is being flagged as "This message contains a link that might be harmful" in Outlook and Teams. We submitted the URL for review via Submissions → URLs twice (over several days apart), and both came back as "Unknown - We checked but can't make a decision right now." We also tried adding the domain to the Tenant Allow/Block List, but the warning in Teams still persists. Per the portal notice, tenant allow entries only override bulk/spam/regular phishing verdicts, not malware/high-confidence phishing — so we suspect the domain may be misclassified at a higher severity level. Has anyone experienced this before, or know how to escalate when submissions repeatedly return "Unknown"?
Submission IDs for reference: 5483d45c-405e-46c8-97e3-08df0cc793fb (Sep 7) and dcaab607-4ead-4791-4996-08df0a6ab25a (Sep 4).

You should open a case with Microsoft support asap and provide the submission IDs.
Once and awhile we have incoming email that will be blocked \ quarantined and we know it is legit. Submitting items is suggested but it won't move the needle much or fast in the way of fixing things. You need the submission IDs for the MS case though as they will likely ask.
I wish you luck.
