I think we have all been waiting a LONG time for this one, so when I saw it announced earlier this morning I simply had to post something about it! Given real-time co-authoring was available in virtually every other desktop app in the Office365 ProPlus suite, Excel has lagged behind a little.
Nevertheless, it’s here now along with some other great announcements in the release, such as Auto-Save in desktop applications, and significant improvements to Microsoft Teams.
