Yes, they are Outlook calendars. We have an Outlook calendar for each of our spare computers. Just like one would have Outlook calendars for reserving rooms for meetings, we have the same thing for spare computers, projectors and other equipment. These are all setup under the resources tab, in the recipients section in Exchange for O365. These are setup as "Equipment" mailboxes, which are free. We want to have an email sent to one or more I.T. staff alerting them to an upcoming reservation in order to prep and have the equipment ready to go 24 hours in advance.
If there is a way to have notification sent, via email or other method by manipulating the equipment calendar settings, I would like to know how that could be accomplished. Since the calendars aren't owned by the people who would get the notifications, I'm not seeing a way to do it through the calendar itself, but I could be missing something. Any method that would accomplish this goal, I would be interested in knowing about, provided it's not overly complicated to setup or maintain.
It seems like this type of thing would be perfect for Flow, and would be useful to lots of people. If it currently doesn't support something like this, and there isn't another way to easily to this, could this be put in as a feature request?
