For users with reader and writer permissions:
These users cannot edit Microsoft Office documents and save them directly on the intranet, but they can download the document, work with it and save it on their own computer. Writers can afterwards upload the edited version, but there will still appear two files on the intranet.
For users with editor and owner permissions:
These users can edit Microsoft Office documents directly from the intranet.
1) Find the specific Microsoft Office document and select 'Actions' and 'Open in Microsoft Word/Excel/PowerPoint' and either open or download it. If you download it, you would have to save it on your computer and afterwards upload it again. If you choose to open in Microsoft Office, you can edit it directly from the intranet.
2) Edit the document as you like and choose to save the document as you would normally do it.
Now the document is saved directly in the intranet, and the new version will be available for other users. All editors and owners can edit documents this way – to see the previous versions of the document
3) Choose 'Actions' and 'Details' and all the previous versions will be available.
Note that if multiple users are editing the same document at the same time, all the versions will be saved, but only the most recent version will appear as the active version.
