Outlook allows a total of 123 revisions to a recurring meeting

Hello,

I would like to have some more info on this: Outlook allows a total of 123 revisions to a recurring meeting

Can somebody explain what is exactly ment by 123 revisions?

Making 1 change to a recurring meeting with 5 occurrences and 5 attendees is that 1 or 25 revisions?

I have only found it on two websites when searching on internet.

Thank You,

Kurt
