Problems getting Sharepoint in O365 external sharing woring

Andrew Burke 0

I may be loosing my Mind so sorry if I am been Dumb today :),

We came across a need in a project to share a folder with an external Client "Great I thought that's easy to do" but for the life of me I can't seem to get sharing working outside of the organization.

We use Sharepoint online (modern sites) nothing complex for the site I wanted to share from I went to Sharepoint Admin --> sharing and set the permissions to allow access to "Specidied People" I also configured a security group to set what user could share the site and set the Guest access levles.

I then went to SharePoint admin--> sites ---> the site in question and set the sharing permissions to "New and Existing Guests"

But even after leaving it for a few hours, I am only getting the option to share it with Internal users

Hi @Andrew Burke ,

I tested it and can't reproduce your problem. According to your description, you should have set up based on these two articles, right?

https://learn.microsoft.com/en-us/sharepoint/turn-external-sharing-on-or-off

https://learn.microsoft.com/en-us/sharepoint/change-external-sharing-site

Is Limit external sharing by domain enabled? Can you share a screenshot of your specific settings? This helps me test in my environment.

Thank you for your understanding. :-)

AS far as I can see everything is set correctly to allow anyone in the security group to share a folder within the site to an external user. but when you go to share all the option available are internal only even the People I choose has the Tag line that's its inside our company only.

We dont want it to be the "anyone setup as we still want our clients to signin/create an account on the B2B setup and we dont want the link shared around.

Hi @Andrew Burke ,

sorry to reply you so late. I did a lot of testing and reproduced your problem. This is strange. When I check Allow only users in specific security groups to share externally, it becomes only available to users within the organization. When I uncheck it, the sharing settings work normally. I also can't figure out why the problem occurs.

To help you better, we recommend you directly create a support ticket from Microsoft 365 Admin Center > Support > New service request.

The support team over there has the correct escalation channel, they can involve more resource and investigate the behavior from back end as fast as possible. They also can check the behavior on your end remotely. You can select online support or phone support to have a live chat with the support engineers. This is the most efficient way for handling this thread as per the situation. I am sure that our Expert Engineers from that side can address this issue effectively and accurately.

Hope it get resolved soon.

Hi @Andrew Burke ,

According to the screenshots you provided, it can already be shared with specific people you choose inside or outside of organization. Try using the private mode of your browser to see if it works. Or use another account with permission to share. Try sharing it with different types of external users to see what happens.

Hi, yes, the setting should allow external sharing, but they don't. that was the point of the ticket.

When we put in an external email address to share to, we get the error. "the link can't be sent because at least one recipient isn't valid" we have tried with multiple external email address but as yet have not been able to find a ways to share externally

Hi @Andrew Burke ,

This is not the expected result.

Please try to end the email address with a semicolon.

See if you can remove the external user from the office 365 admin center. They will be marked with #EXT# in the username.

Additional notes

At the Office 365 admin center level, user management lets an administrator manage users (create, delete, license, and assign delegated admins) in the Azure Active Directory domain structure. The portal also allows for the management of external users for site collections, including personal sites.

you are unable to even enter a semi colon after the email address, it will just default to the nearest match in the GAL.

The "Email" user does not yet exist in our external users "B2C" setup. sending the share should trigger them to have to create an account and they will then appear.

We have also tried setting up external sharing as anonymous but yet again we are unable to send the sharing link becuase entering anything apart form an internal email give us the above error.
