We started getting this error when attaching a file from SharePoint or OneDrive as a link. It says an error occurred when updating permissions for the file. There is a workaround but want to know if there is a permanent fix. The workaround is to click on the down arrow of the attachment, click change permissions and then choose the permissions but there should be a way for it to happen automatically. If you don't do the workaround the receiver of the email has access denied for permissions.

We are already discussing the issue in this thread: https://techcommunity.microsoft.com/t5/Outlook/Modern-Attachments-Cannot-set-perms/m-p/124559#M1124

Thanks @Salvatore Biscari, I went to that thread and I see there still isn't a solution, but I'll keep checking back.
