How to allow access to external users with same email

Question

I have a company SharePoint site (SharePoint online) with my employee users having their emails as user@xxx.com. I would like to have external users from another company automatically have access to the site without the need to individually approve them or add them. Is there a way to allow any user with a user@yyy.com account enter the site?

Thanks

For this we need to enable the external sharing for the site from SharePoint admin center, we need to follow the below steps to enable external sharing :

1. Go to the Active sites page of the new SharePoint admin center, and sign in with an account that has admin permissions for your organization.
2. In the left column, select a site.
3. Select Sharing.
4. Select an external sharing option
5. If you want to limit the sharing of this site by domain, select the Limit sharing by domain check box, and add the domains that you want to allow or block.
6. If you want to change the default sharing link type, permissions, or expiration setting for this site, clear the Same as organization-level settingcheck box and set the value that you want to use for this site.
7. Select Save.

Note:

• For your scenario, need to select the below option :

Existing guests 

Allow sharing with only people already in your directory. These users may exist in your directory because they previously accepted sharing invitations or because they were manually added. (You can tell an external user because they have #EXT# in their user name.)
