Outlook Search Folder for External Senders
According to Diane_Poremsky_MVP's post, you should be able to achieve this by filtering on "@": https://www.slipstick.com/outlook/rules/filter-internal-mail-from-external-mail/

asked for a search not a rule. What you are proposing as been proposed in every single post where people needs to have a search folder. It's close, but it's not responding to the need and I don't believe anything respond to the need with the new outlook. Legacy outlook can create complex search folder and it would take seconds to create that search folder. Hopefully microsoft will enhance the search folder, but I can't see it on the roadmap for Outlook at all

I wish people would stop proposing this option as it's not a solution to what shocko asked. He did not asked for a rule, but for a search. I've seen this answer way too many times. It does not respond to the need. The search folder is very very simplistic and lacks a lot compared to what we have in the legacy outlook. You can't combine rules, you can't even add keywords. Keywords would be pretty basic.

This involves creating a rule which Schocko nor I want to do. We want to be able to sort by external only OR create a search folder by external only. I have been searching the web for the past day or so and have found nothing.

You can basically do the reverse of this;
Search Folder or Conditional Formatting for internal company emails - Robert 365Instead of specifying the From field on the Messages tab, select the field on the Advanced tab so that you can use the "does not contain" condition.
This will filter out the internal emails, thus what is left will be the external emails 😉
Depending on how you've configured your email routing between on-prem, cloud and other mailing instances that you are using, you could also filter based on several message headers. You may need to find out first which will apply to your organization (one or more could apply);
- X-MS-Exchange-Organization-AuthAs: Anonymous
- X-MS-Exchange-CrossTenant-AuthAs: Anonymous
- X-MS-Exchange-CrossTenant-FromEntityHeader: Internet
Internal messages would have AuthAs values of "Internal" and FromEntityHeader of "HybridOnPrem" or "Hosted".
Note that this only applies to Classic Outlook. New Outlook and Outlook on the Web will get more advanced Search Folder support (on a not yet determined date) in the future.
