Outlook add-in License_free

hi, im a nextcloud adminstrator. i used nextcloud for about a year, and im going to solve the outlook attachment with outlook add-in. I tested the integration for a long time and see a pdf in the app location:https://download.nextcloud.com/outlook/20180705/Outlook.plugin.-.License_free.pdf
“The max allowed system users are 50”
MY problem is :Is this limit for the free edition?the normal features?
I didn`t saw this doc before。Does it means that the 2301 free edition limited to 50 users now?

Hello heaven4,

This is a limit for the free-edition. The document is embedded in the installer and has been in the installer as from 2017 (version 2.1).

Kind regards,
