Kristina,

Although this feature is not built directly into Confluence, in case it helps, it is available through our third-party Cenote Lockpoint app. Attachment locking works with both the original Edit in Office as well as the newer Atlassian Companion implementation. If this sounds interesting or if you have questions, you're more than welcome to reach out to us directly on our support site.

This is hugely important for collaboration on documentation. While we use pages for documentation that can be shared between us and our client, we do have the need to send out 508 compliant Word and PDF documents to end users like hospitals and other health practitioners. These files need to remain as Word attachments on the Confluence site and there is a strong need to be able to collaborate on the update of those attachments without losing work if more than one person is updating at a time. SharePoint has this feature and it is amazing. Confluence needs this ASAP to remain a strong collaborative tool!  

Same here! This feature is a must-have, please please add this!

Concurrent editing is not needed; we just need users to know when someone else has opened a document (Excel) but hasn't saved it back to the page.

We have same kind of issue in my company (7500 active licences)
This feature is a must-have.

We really need this as we have multiple users that update complicated rosters in Excel that are attached to the page. Probably another issue but we are getting an error when using the Office Connector to do with Basic Authentication and SSL. Yet to work that one out but having warnings when editing the same attachment would be great.

Two people or more can today edit a confluence page and save it and both their work will be saved without any losses or conflicts. Can´t you come up with a solution for it with attachments and macros ?
Thanks.

@Mark absolutely - I vote for both concurrent edit abilities AND also ability to show if someone already has the attachment open.

The latter would be my preference to happen first since it's most detrimental to our workflow.

@ Alice - concurrent edit would be a nice to have....

I have the same comment as @John Price. We don't need the ability to concurrently edit, just a warning or pop-up (as would normally appear if opening the document on a desktop) that says someone else has it open.

We would like this as well. This would prevent to users from overwriting each other's word/excel documents.
