I know it's possible to overlay calendars in Outlook (2016) or to view them separately, side-by-side:
[Calendar 1 / Calendar 2] or [Calendar 1] [Calendar 2]
I would like to have two groups of overlayed calendars, because I share calendars with several colleagues, but would like to be able to focus on my own calendars. So something like:
[Calendar 1 / Calendar 2] [Cal. A / B / C D]
Is this possible, and if yes, how? My google-fu failed me, but maybe there is no such option in stock Outlook.
