Limits to number of co-authors
Is there any published information regarding limits to co-authoring in Office Online? I've received some reports that Excel sheets were nearly unusable when the number of co-authors went above 10. I've personally never edited with this many authors, but I can't find any documentation with any hard limits around this.
Thanks!

- Ok, So, recommended is no more than 10, but the maxium is 99 :P, so I guess your experience is on par with expectations. Reference here https://docs.microsoft.com/en-us/SharePoint/install/software-boundaries-and-limits
"Recommended maximum number of concurrent editors is 10. The boundary is 99.
If there are 99 co-authors who have a single document opened for concurrent editing, each successive user sees a "File in use" error, and can only open a read-only copy.
More than 10 co-editors will lead to a gradually degraded user experience with more conflicts, and users might have to go through more iterations to successfully upload their changes to the server. "Since that article applies to Sharepoint 2013, do you think it is relevant here? It could be that co-authoring limits are the same across products, but I'm not certain of this.
And the users in question were either using Office Online embedded in Teams, or using Office Online directly. We don't currently support the Office 365 Pro Plus deployments, and our Office client applications are not signed in to Office 365.
