What version of Excel (on Windows) is required to do co-authoring?
I recently say this post: https://blogs.office.com/en-us/2017/08/31/new-to-office-365-in-august-enriching-teamwork/ That says Excel real time co-authoring is now generally available. What version of excel (on Windows) is required to make this work?
- Eric, - co-authoring is available as of version 1707 build 8326.2058.

- John GruberBrass ContributorI had issues with co-authoring. I had to make two changes: 1. https://support.microsoft.com/en-us/help/3185078/how-to-switch-from-semi-annual-channel-to-monthly-channel.2. Disable "Refresh data when opening the file" on the pivot tables in the workbook.To disable "Refresh data when opening the file":
 1. Open the workbook.
 2. Highlight a PivotChart.
 3. In the Analyze ribbon click Options.
 4. Go to the data tab and uncheck "Refresh data when opening the file".You may need to repeat steps 2-4 on each PivotChart.
- Dmitri KotchetovMicrosoft Yes, this is the right build, it also has to be O365 subscription.
- Detlef_LewinSilver ContributorEric, co-authoring is available as of version 1707 build 8326.2058. - Rob BarkerIron ContributorI have two users running Version 1708 Build 8431.2236 ...higher than the stated requirements for desktop Excel co-authoring. Neither of them can open an Excel that I shared with them from my OneDrive for Business. They can co-author in Excel online (i.e., the browser version) but they cannot co-author in Excel desktop (the file will not open for them if I already have it open.) If I'm not in the file, they can open it individually and save changes, which I see later after they've closed it and I re-open it. They are on Office 365 semi-annual channel and I'm on Monthly targeted channel. They do not have the AutoSave button in the upper left corner of Excel (which I believe it supposed to provide a good visual indicator that the user has the correct version for co-authoring.) How do I get them co-authoring in Excel desktop? What version is required? - Rob BarkerIron ContributorDoes anyone have an answer for this?? 
 
- Rob BarkerIron ContributorI have a user that is running 1708 build 8431.2153 (and I'm running 1712 build 8827.2117) and I shared a workbook with him that is stored in my ODFB, but he doesn't see co-authoring (i.e. there is no AutoSave button for him.) Any idea why that would occur? - Detlef_LewinSilver Contributor
