Simultaneous authoring

Question

Dear all,
I'm currently working on a project where more than one user simultaneously edit the same Word document. Any advice about the best collaborative authoring/editing tool that keeps tracked changes? We are trying OneDrive but are having challenges because some
team members use MS Word 2013 while others use the older 2010. Also it's handling of pasting external content and formatting is not quite helpful.

Answer 1

In Organisations using OneDrive, two or more people can edit a word document concurrently. To do this, click OneDrive in the header of a SharePoint or Office 365 site, then click the ellipsis (…) to the right of the entry. Then click ‘Share’ and invite the
other user to view or edit the document, and click ‘Share’ once more. To add to the list of people already sharing a document, click the ‘Shared with’ icon in the ‘Sharing’ column and invite the additional person to view or edit the document, and click ‘Share’
once more.
When someone invites you to share a document, you’ll typically receive an email notification with a link to the document. Clicking the link opens the document. If you have edit permission, your changes are automatically saved.

AFAIK the fact some users have Word 2010 and others have Word 2013 shouldn't affect this. Differences in the pasting of external content probably has more to do with the way the different users have Word configured than with the Word versions.
