[kesselb]

• Resolve RateLimiting, Too many addressbook or calendar share requests when adding user or groups to a calendar #60338

Summary

The current rate limit allows 20 share/unshare/can edit requests per hour per user.

If one want's to re-organize calendars or addressbooks 20 can be bit tight, hence changing the default to 100.

Approved.

But I would go with something in between 20 and 200. 20 is low but 200 is a bit high
