Dear Ethan YANG1,

Thank you for posting your query in our community.

I understand your concern and would like to convey that there are couple of methods to achieve it,

method 1

if you want to share a fine to a user and if he don’t want to login to any office 365 account you can follow the below steps. ( please not that you need to enable external sharing otherwise this option will be blurred out if soPlease refer to this article Change the sharing settings for a site - SharePoint in Microsoft 365 | Microsoft Learn )

• go to SharePoint site >> right click on the file >> share >> gear icon >> anyone>> apply >> email address.

Please refer to my screenshots

Method 2

You can share a file but user have to logging to office 365 by email address you use to share the file.

• go to SharePoint site >> right click on the file >> share >> gear icon >> people you chose >> apply >> email address.

I hope this helps If you have any additional questions or if you need any additional help regarding this or anything else at all - let me know, I'll be here to help you out.

Dear Ethan YANG1,

Thank you for providing the necessary information about the issue you are facing.

For your first issue you have to enable external sharing to share files with anyone link.

Please go to SharePoint admin center >> policies >> sharing >> set to anyone

To change the external sharing setting:

1. Go to Active sites in 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. (For a channel site, select the link in the Channel sites column and then select the site.)
3. On the Settings tab, select More sharing settings.
4. Select an external sharing option (see the table in the next section).

For your second question YES if you share SharePoint site the user required to logging to Microsoft account this is expected behavior.

As a workaround we suggest you to crate a gust account to the user in your tenant. click here to learn how to crate a gust user --->> Guests in the Microsoft 365 admin center
