External sender flagging on all emails in Outlook
Hi, as a Consulting Firm using MS365 and the new Outlook, 99% of our incoming emails are from external senders. Outlook has suddenly started flagging these as suspicious, resulting in 100% of my inbox being flagged as suspicious, whether or not the contact is in my address book or the email and domain are white-listed in my account. This is extremely frustrating and completely defeats the purpose of the action. How can these false positives be eliminated?
Thanks Matt, we managed to get it fixed by adjusting the Augmentt settings.

In New Outlook, external sender alerts come from Microsoft 365 security settings. If all emails are flagged, your admin needs to adjust the anti-phishing policy in Microsoft Defender to trust known senders or turn off the tag.

Is it flagging them in OWA as well? If so, then I'd start with checking DNS records. Be sure yours is up to date with SPF and DMARC for sure.
If only in Outlook, then you can try creating a new profile and see if that helps. I know of a person last week that it did fix it for them.
Thanks Lisa, much appreciated! Will try this and see if the problem is resolved.
