Enable an option to display declined meetings in teh calendar (in settings). Often initially one is not available for a meeting, but then due to changes of schedule might be able to join, but since that meeting is not displayed in calendar, simply forgets about that. I found that option very helpful in Google mail that we used up to now in the company.

It is my manual task to always block some time before and after meetings, lot's of extra clicking in Outlook. I would love to see a feature or someone explain to me how I can tell Outlook, to by default make my meetings appear to start 15 minutes earlier and stop 15 minutes later, than they actually do, so no one can book back to back through my entire schedule.

I would like the option to send meetings requests with BCC, CC so all information about all invitees is not shared with everyone that is invited

Also, Outlook calendar entries need BCC, CC – without showing these and need to extend them to Skype as well as Microsoft Teams Meetings.

Outlook needs to have Bcc functionality for ZOOM invitations. if I want to send a mass invitation out without losing ZOOM's full functionality I cannot do so without sharing everyone's email addresses in a public way. It's 2020 and this application functions like its in Vista.

You should be able to (under tracking) easily email or reach out to those who have not responded to an outlook invite to a meeting request. The only way I see it can be done now, is to hand extract those individuals and resend a new meeting request.

Be able to set an email reminder for an event in your calendar

Sometimes the owner of a meeting (or, more often, meeting series) is on vacation or changes jobs; it would be nice if they could assign ownership of an instance (for vacation) or the full series (for job changes) to someone else. Also provide an option to create a meeting on someone's behalf without being included in the meeting.

It is helpful to have a record of past events/meeting as they happened.
Currently, modifying a recurring event (e.g. moving a team meeting from Tuesdays to Thursdays) will change all occurrences, past and future, which means the record of previous events is lost/not accurate.
When modifying a recurring event, users usually want to implement a change "from now on", so at the very least they should be given the option to modify (a) single event, (b) future occurrences, (c) all occurrences.
See Google calendar for implementation.

Please give us back the opportunity to categorize meetings with different colours

The recurring calendar options are weekly, monthly or yearly. I do several things quarterly and would like that option.

be able to invite internal distribution lists to recurring meetings where the distribution list stayed as the invitee, not expanding the members of the list at that point in time but still able to send to the existing list. As
a result, when the distribution list membership was updated
new members receive the meeting invite and if a member is removed from the list they would be removed from the meeting.

Create an option for quickly generating follow-up meetings that let a facilitator schedule a new meeting in the future with the same information as the old meeting. It could prompt for a location, time, and date update while retaining the previous meeting's content like an email thread.
Thanks for considering!

Provide an option to clone a past meeting as we might need to create meeting which is not a recurring one would be the best option in Microsoft Outlook 2016. Being able to clone a past meeting would be good instead of copying all the details again.

When creating an appointment or meeting in your calendar you should be able to create an auto reply (out of Office) associated with that calendar event. That way if you have multiple periods that you will be out of the office you can have it set up without having to remember just prior to the appointment.

Allow the copying of an existing meeting into a new meeting that can be edited for content, attendees, time, etc., and then sent. This dramatically decreases the work effort of scheduling meetings and reduces friction between your users and the software.

Whenever we cancel a recurring meeting , each time it as "only this meeting " or whole series.

It would be good to have an option where it allows us to select some number of meeting invites.

For Example: If a recurring meeting is sent for 3 weeks. and if user want to cancel the meeting for 1 week , the popup should have option to select from and to dates and to cancel all 5 days meeting invite at once.

It would be great if we could search calendar items in the calendar regardless of how the calendar is added.
