Does Microsoft Office 2010 have version control?
Solution 1:
No. It has AutoRecover and Track Changes but not a versioning history.
You may be interested in using P4OFC if you need version control on Office documents.
Perforce Plug-in for Microsoft Office
P4OFC, the Perforce Plug-in for Microsoft Office, allows Microsoft Word, Excel, PowerPoint, and Project files to be easily stored and managed in Perforce. With P4OFC, users don't have to leave a familiar environment to bring their documents under Perforce control.
Support for Basic SCM Tasks
P4OFC helps everyday users to:
- Check files in and out of Perforce from within Microsoft Word, Excel, PowerPoint and Project
- Determine which version of a document is checked out and who else is working on it
- Access complete document revision history
- Share and lock documents through Perforce
- Link change requests with document changes
Implement Document Management Quickly and Easily
P4OFC is easy to install and adds a "Perforce" menu to Microsoft Office applications. Once installed, the plug-in automatically determines which documents are under Perforce control.
Quickly Compare Two Versions of the Same Word Document
P4OFC can compare any two revisions of the same Word document and quickly show changes, using Microsoft Word's Track Changes feature.
A Perforce repository is free for two users.
Solution 2:
A Word file can contain multiple versions. Use menu File | Info | Manage Versions.
Otherwise, it is only possible using some external software (version control or SharePoint).
Solution 3:
Word used to have built=in Version Control. But that was removed in Word 2007:
