License-checks are done each time the application is accessed by a user.

An invalid license will never have any impact on Dynamics 365, it only limits the addon itself.

With version 4.64 you have the possibility to set up for each service activity a specific color. GroupCalendar setup will create automatically a picklist attribute on the service activity entity which is used for this feature. To activate color-coding for service activities, you have to add this attribute to the main form of the entity. The attribute is named ptm_colorcode with the display name Color and is predefined with 12 colors.
