Unable to share files in external

Question

Hi,

Since about 2-3 weeks, we are unable to share files of our Sharepoint in external.

We were able before that. As far as we know, none of our settings changed. I followed all the articles I found about error OSE303 and OSE304 and it's not working. Our settings are to the most permissive.

How can I resolve this issue?

Thanks

Please follow below steps to troubleshooting the issue.

1.You should enable external sharing in both tenant level and site level.
(1)Tenant level: SharePoint admin center -> Policies -> Sharing -> Set the sharing policy.
(2)Site level: SharePoint admin center -> Sites -> Active sites -> Select the site -> Click “Sharing” tab -> Set the sharing policy.
2.If the site is office 365 group site, you need to enable the external sharing via PowerShell command for office 365 group site.

$adminUPN="user name"  
$orgName="tenant name"  
$usercredential = Get-Credential -username $adminUPN -Message "type password"  
Connect-SPOService -Url https://$orgName-admin.sharepoint.com -Credential $userCredential  
$siteurl="https://$orgName.sharepoint.com/sites/desired_site_collection  
set-sposite -identity $siteurl -sharingcapability ExternalUserAndGuestSharing  

3.If the site is SharePoint classis site, you need to go to office 365 admin center -> Resources -> Sites -> Select the site, check the Sharing Status.
4.Go to site settings -> Site permissions -> Access Request Settings, check if you have check the option “allow members to share the site and individual files and folders”.
5.Change external sharing settings according to this article.
