Tenant Allow/Block List will allow related URLs
Applicable to Tenants with Exchange Online Protection, Microsoft Defender for Plan 1 or Plan 2 or Microsoft 365 Defender plan.
Email messages can be blocked because of a bad URL where the URL is a matched based on a sub path or portion of the URL contained in the message. In the case of a legitimate email getting blocked, this was difficult to correct through a submission. We have updated the way that we handle allowed URLs such that the partial matching behavior is included without the need to include wild cards or making multiple URL submissions.
