Co authoring in Microsoft 365 limits

New Contributor

What is the limit of users co-authoring files in Microsoft 365?
I couldn't find anything official about it.


The answer I see most plausibly is that it depends on where the file is stored.


Is that correct? Does anyone know this information?

No, it's not the end, documents are stored in SharePoint Online. If my memory serves well, this limit has never been documented...back in SharePoint 2013 times, coauthoring was limited to a maximum of 99 co-authors so I bet in SPO this limit is higher...My I ask what scenario you have in place?
Thank you Juan!
I don't have a specific scenario, it's just a question that I haven't found the answer in any docs.
But, if I have a team of 200 users on Microsoft Teams, can they all co-author? What is the most you have ever known?
The limit is based on *concurrent users*, so it does not matter how many people are in the Team, just how many need to have the document open to edit at tge same time.
