I am looking at Office 365 as a viable alternative to Google Apps. One of the most useful features of Google Calendar is that I can have multiple reminders specified. So for instance my default is to receive a reminder 2 weeks ahead, 1 week ahead, 2 days ahead and 2 hours ahead.

I can only see an option for one reminder on the Office 365 calendar and can't see how to add more. This is a serious omission. A basic calendar requirement in my opinion.

Please restore email reminder functionality to calendar! I rely on this to keep track of my schedule and I'm now using Google calendar because I can't get this Outlook.com beta to send me email reminders.

I had previously manually created a “family calendar” that I shared and was therefore visible on outlook web, app and iOS calendar app. The latest update seems to have absorbed my manually created “family calendar” items into the new “my family” shared calendar which I do not recall being ask d permission for, however this new “my family” calendar is not visible in iOS calendar. Please resolve ASAP as not everyone uses the outlook app.

We would like to print the calendar for any range of dates and list all of the scheduled events date and time etc

The selection of colors for calendars is very limited, and the 9 choices given have several that look very similar. I would love more choices, or at least choices that are more distinct from each other.

Love the email section

When using the beta calenadar, I no longer have today's calendar items on the right hand side on the month view.

I prefer month view and to see today's list.

The ability to easily set an auto-reply or Out of Office message is very important, and the ease in which OWA has implemented it in the past was great. Very surprised Automatic Replies are not included in the Beta.

With Outlook.com beta it appears I can no longer create new entries in the Birthday Calendar.
Also, I can no longer edit existing entries in the Birthday Calendar to change the Reminder.
If I leave the beta, I can again add new entries to the Birthday Calendar and edit existing entries to modify the reminders.
Please bring this functionality to the Calendar beta.

See the to-do task list in the calendar in a different format (not like events), like the weather. The fact that calendar and task are using the same calendar but you can't see them in the same page is awful!

Create new task, birthdays or events directly from the Calendar.

The options for adding new calendars were easier to find when they were at the top of the page; now I have to scroll down to the bottom of my list of calendars to find them. It also does not make sense that the "From file" option is under "Discover calendars". If I have a file I want to add the calendar from, then I already know about that calendar and don't need to discover it, so I wouldn't look for that there.

The new Calendar is garbage. Please keep the new Mail layout but revert back to the old calendar layout.

Beta mode took away the ability to add an iCal attachment directly to calendar. I love the beta so far and would really like this feature to come back.

add 45 minutes option in the list of time slot available in the endtime field when creating an invitation
lot of people don't need a 30min or 1h meeting but 45 to have some buffer
the same can be achieved by macro but we can ask all employee to create a macro for it

Merge with calendars from other providers (e.g. Google)
I would like to link my Google Calendars also and get an overview on all my Events in the same view.

Thread says Beta calendar is fixed to have reminders, but it still doesn't allow the email reminder. Still missing important functionality of Classic calendar.

Outlook recurrence patterns currently include "Daily", "Weekly", "Monthly", and "Yearly". Can a "Quarterly" recurrence pattern be added? This would save time having to manually insert reminders in the calendar each quarter.

Old search in Outlook calendar required less clicks, had instant results, and the results showed on calendar in current month view. New experience requires me to complete my query and click search. The results are displayed in a chronological list which means the event I was looking for was at the bottom.

I cannot add nor remove weather locations in the calendar, I must switch to non-beta version to do that. Why?

Please add the capability to duplicate a calendar event (not the same as repeat).

It could be done by right-clicking on an existing event, or by openning it and selecting to duplicate from an option menu.

Then allow changes to the newly duplicated event before saving.
