I never hear the reminder of calender entries - this used to be one of the main features of old mobile phones - with current phones it's nearly useless. I don't always have my phone right beside me and even less I persistantly look at it. Therefore, for me the volume should be significantly louder and the tone should last much longer, so I can also hear it, when there's other noise around me.

It is really long winded to get birthdays showing on my phone in the 'birthdays calendar'. Surely this can be simplified so once I've entered the birthday on my phone contacts they come up on the calendar - I've been told I have to do it on my PC first!

Microsoft should take an inspiration on Nokia. I suggest this style: If You have month view by tapping on day, You see Your day appointments

Rather than scrolling [0..59], it would be more efficient to scroll [0..5] [0..9], especially for times on the half hour

I'd like to be able to move an appointment from one calendar account to another by editing an appointment.
Today if I've made a work entry in our private calendar, my wife gets notifications. Then I have to make a new one, and delete the old. Would be nice to just change the calendar where the appointment is.

I sync my phone calendar with different calendars but when i'm working, I don't need to know what my partner has on, or other events not relevant. If i had the choice to only view one certain calendar from the locked screen, i wouldn't miss the important things but still be able to open the calendar to see other events from the other calendars when needed.

Please change auto delete on phone calendar as you can not check a previous entry over 2 weeks old this is very frustrating and when you check on Outlook on pc there is no search so you have to go through all the entries until you find it, this is very basic stuff and is much more important than updating calendar with pretty colours.

If you have a recurring event with multiple occurrence within the week itself over a period of time, eg. Extra math tutorial lessons on Mons and Thurs for 4 weeks.
Instead of creating two repeating events on Monday and Thursday, combine both occurrence into one event.

That way we can monitor a calendar on the phone, but aren't bothered by the notifications.

Include upcoming tasks in the calendar livetile, or give tasks their own livetile.

Please provide better support for Google Calendar syncing with a Google Calendar app. I read that Microsoft removed this and that makes absolutely no sense. You can get on Windows on your computer and do this, so why not on your phone?

I have about 6 calendars in Google, and I can do nothing with them on my windows phone. These are detrimental to my work life.

PLEASE fix this. Yet another reason I may go back to Android

When I make a new item in my agenda, the calendar drop-down menu shows the colour of the calendar. However, in the to-do list, it only shows my theme colour. Additionally, the to-do items themselves don't use colour to indicate which item is in which calendar.

Why does it need to be swiped up and down when everything else on the phone goes side to side?

View of daily appointment in live tile in home screen also when there are some appointments for tomorrow

Make flagged mail to be shown as to-do in Calender hub is very important.
Outlook users used to flag mails as tasks with due dates. We can simply take a look to the calendar and find out what mails haven't been processed. This is very productive way to organize our schedule. It should be placed in Windows Phone to "save us from the phone."

Allow users to determine for how long appointments entered in OK are available on the phone.

Month overview could badly do with icons or colors appearing within it so I at least knew which of my calendars has entries in particular days. Be nice to be able to select a day in the month view, and at the bottom the days entries appear in an overview, without zooming in on the day.
