Categories in meeting rooms combine meeting rooms for calendar events.
If you have several offices in different cities, combine meeting rooms into categories for convenience.
Go to the Meeting room availability section and click on the Meeting rooms button.
In the menu, select the Add category option.
Name a category and add the desired meeting rooms. Click Save.
To change category, click on the ... menu button and select the Edit option.
If necessary, you can Delete the category. In this case, all meeting rooms will be moved to the general list, outside the categories.
