Outlook limit on display Team calendars

Question

Program: Outlook 2010 / 2013
Feature: The automatically created calendar group "Team <Manager name>", that is generated on basis of Active Directory attribute "manager" each time Outlook starts.
When the manager has 50 or less employees, Outlook will automatically generate a "Team <manager name>" calendar group. When the manager has 100+ Outlook stops to generate the list / show the list. 
What is the precise limit, before Outlook stops to generate the list? 
Can it be raised?

Hi,
There is no document about that there is a limit on displaying team calendars.
Per my known, in Outlook 2010, there is a default limit of thirty (30) calendars that can be displayed in the Calendar module at one time. You can modify this limit, but this limit is up to 100. You can try to reduce the number of employees to 100 to check
if the team calendar can display in Outlook.
Here is a related blog for your reference.
