If a day to book for a recurrent meeting falls on a holiday, it should be rejected automatically and enable us to rebook the item on another day.
Therefore, it would be great if you could add such a setting.

Currently the Office 365 group calendar is disclosed only to the group members, but I want other users to see the group calendar as well. It would be great if I can let user see the group calendar without adding him to the group as a member.

We can request recipients to share their calendar with the Share Calendar option in the Outlook client for semi-annual channel. So, it would be great if Ootw would have the similar requesting feature for the calendar sharing.

With the old Outlook Experience, you could ensure that any items added to a shared calendar by another person you were sent an email notification. The actual setting was "When someone updates an event or task on this calendar, send details of the change to:"

This seems to not be available with the new Outlook experience, or hidden somewhere that is not easy to find.

Could you please add this back in, as it is most useful for Shared Calendars, and available with other email/calendar services such as Google.

Set the additional buffer such as travel time in addition to the actual meeting duration when scheduling meeting rooms.
“End meeting early” is the similar function but it cannot add the buffer time. So, it would be great if we could add the travel time.

I like that we can set a default meeting setting for Skype or Teams, especially now that we are working from home and all of our meetings are online. It would be great if we (individual users) can choose which one -Skype or Teams- we want to be our default online meeting setting. My org predominantly uses Teams for online meetings, not Skype; so it would be helpful to have that as an option for my default meeting.

I don’t want the meeting to be added in the calendar of users who are invited in the meeting but added in the BCC. We just let our managers to know that we are going to have a meeting by forwarding the invitation to them, so I would like to block adding the event to their calendar.

Currently, if you check the Allow conflicts box in EAC to double book for a meeting room, it will be possible to double book the room by unlimited users.
So, we would like to set the max number of the users who are allowed to double book for the meeting room.

In the mail outlook view, we can select the calendar sidebar. Please provide a feature to pin the calendar sidebar.

I turned off the setting which deletes my emails once I accept a calendar RSVP.
However, the emails are still being deleted regardless.
All of the RSVP emails I receive for work contain important information. Constantly retrieving them from my Deleted Items after hitting accept is unacceptable.
Please fix this setting, or better yet, DO NOT ENABLE IT BY DEFAULT.

It would be great that we could add group members’ calendar when adding the mail-enabled security group into the calendar same as Outlook client behavior.

I would like to set “Free” as the default value in Show as when creating an event in the Outlook on the web.

As a user I would ike to be able to set the default to OFF (unchecked) for "Request Responses" - I rarely want responses and don't like my inbox filled up with them.

Allow users to rename the default "Calendar". I have it synced to another app and the calendar name is just "Calendar", which isn't helpful.

It would be great if you could implement a feature to tentatively book more than one schedule on different day irregularly in bulk on the Outlook client window.

After we added the organizer name to the subject, the calendar item shows the meeting subject following the organizer name. I would like to customize the item to show the organizer name after the meeting subject.

I like the feature that you can combine the calendar from Outlook.com/Hotmail/Live/MSN or Google with your work calendar to view and manage your personal calendar.

It would be great to add more types of personal accounts and also be able to add another O365 account, as I'm using O365 for work as well as for personal use - but 2 separate subscriptions.

When the use of resource mailbox is restricted by the address book policy, it cannot be controlled from "Search conference room", so I would like to be able to control it as well.

アドレス帳ポリシーでリソースメールボックスの利用制限をかけた際、"会議室の検索" からは制御が出来ないので、こちらも制御できるようにしてほしい。

When a sub-calendar is shared with a user and his account is to be deleted due to his retirement and others, it would be great if the ownership of the shared calendar could be moved to the other user (one of the members shared with).

We have two different resource mailboxes which has similar name and we would like to distinguish these two by icons. In order to make this possible, we are hoping to be able to change icons of resource mailbox.
