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.

Currently, Browse with Room finder option is unclickable and does not provide any room option if we click it when we try to add the conference room from Scheduling Assistant in Ootw calendar.
We can select the option by using arrow keys and Enter key but using the keyboard every time is inconvenient. It would be great for our operation if we can click to use the Browse with Room finder option in Scheduling Assistant.

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.

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.

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.

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

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 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.

It would be great if you could add a feature for administrators to check who added a personal account to the personal calendar and TeamSnap account, and remove it forcibly.

It would be great if we could control sending a notification of changes which is automatically sent every time when users change the setting of the shared calendar.

Users who have a reviewer permission of the Outlook calendar can see peoples’ calendar item details such as event title, location, organizer by clicking the event. If any Teams meeting is scheduled, its URL can also be visible to reviewer users, even if they are not invited in the Teams meeting.
So, I would like to hide the URL of Teams meeting from non-attendees.

It would be great we could switch the Add online meeting option from Skype Meeting to Teams Meeting after sending the invitation in Ootw calendar.

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

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).

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.

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 you enable the option to automatically add online meetings to new events, it adds a Skype meeting, and you can't edit that to be Teams even before you save/send the meeting request.

If we add an event organizer as the attendee for the event, the event message won’t be delivered to the organizers’ inbox somehow. This type of message will be delivered to the Deleted folder in Outlook client, and for Outlook on the web, the message won’t be delivered anywhere.
