Hi Steve,
Q1:
I suggest you try turning off protected view in Office applications:
If the notification persists, I would like to confirm the following information:
- Some screenshots of the notifications. One for "open as read-only initially", one for "have to click a link to be able to edit" and one for "files from the internet can contain viruses".
- Did you open document from online or the synced folder in local PC?
- Have you set require check-out for files in a library. Please also capture a screenshot of the versioning setting page
Q2:
By default, if all users have edit permission, they can open the same document simultaneously from online or client andCollaborate on Word documents with real-time co-authoring. For your situation and to better answer your question, I would like clarify your situation first:
- A screenshot regarding "As far as I can see, if both are online then it will lock the document to a user,".
- Did you do some settings for the SharePoint site?
I believe every products have pros/cons. I suggest you do more tests in SharePoint online. And welcome post some new threads with your questions, we will try our best to support you.
Regards,
Linda
