How to Enable and Use Exchange Online’s External Email Tagging Feature
Exchange Online tenants can activate external email tagging, which causes Outlook clients (not desktop yet) to highlight messages received from external domains. The feature can replace custom implementations to mark external email, usually done with transport rules. It’s easy to implement and control, but the mail tip offering to block an external sender seems a little over the top.

TonyRedmond Do you know if there is there a way to change the layout of the tag in Outlook to make it stand out a little more? Currently it has just the small exclamation point and the text "This sender xxx is from outside your organisation". To really make it less subtile and have a better effect.
Best regards

- I don't believe you can customize any aspect of the warning.
- Victor_IvanidzeBronze ContributorThere exists is a Windows program that allows you to modify the configuration of external sender identification. Use it if you don't want to run Exchange PowerShell.
Google for "SetExternalInOutlook for Office 365".

Thanks. I have this enabled for my clients since last year and it seems to work great in Outlook online and in the Outlook app. Not sure why its taking so long to enable the feature in Outlook.
