Please add recurring todo/task in calendar. It was available in WP6.5 and even earlier.

For example create an appointment with following pattern:

Ring every monday and thursday at 7 p.m. for the next ten weeks

我對新的 Windows Phone 7 的系統很滿意，
很且適應良好，
但有一件事讓我不得不囉唆一下：
我是重度行事曆使用者，
一直都是使用outlook來安排與提醒每天重要的排程，
行事曆配合 Windows Phone 7 手機等於是我的助理，
從以往的「Windows Mobile」開始我一直用得很滿意，
也重度依賴者以往的「Windows Mobile」智慧型手機，
然而最近我換了Windows Phone 7之後，
卻招來一場惡夢，
因為所有每天大約一二十次不等的行事曆提醒，
我都會一再一再一再地錯過，
原因在於手機的提醒只會振動一次，
聲音也只有短短地十種內建二秒左右的音效可以選擇，
如果放在包包或是手機皮套裡或是周圍噪音大時根本就起不了作用，
我要工作也不可能一直將手機拿在手裡，
為何以前的Windows Mobile都可以換鈴聲或是可以選擇提醒的頻率，
但現在 Windows Phone 7卻一點也不可以？！
鈴聲不能換或許是因為智慧財產權我可以理解，
但是提醒聲音或振動的頻率以及長度為何也沒有選擇的餘地呢？
這樣一來所謂的提醒根本起不了提醒的作用不是嗎？
我相信一定可以修改，
原先我以為是手機供應商的問題
但它們卻表示這是 Windows Phone 7系統設定的
希望 Windows Phone 7能重視行事曆這一個區塊的使用者，
畢竟對一直會選擇 Windows Phone 7系統的智慧型手機使用者來說，
行事曆OUTLOOK會是一個重要的原因，
但今天這個秘書卻無法即時的輔助到我，
只能有氣無力的讓我感覺不到它的存在，
這真的讓我很糗、很囧、而且影響到流程以及工作，
麻煩一下 Windows Phone 7，更改一下提醒的程式好嗎？
至少讓我可以選擇提醒方式它的「頻率」或「選擇提醒的時間長度」！
現在實在太不人性化了，也失去了行事曆的提醒意義。
很不人性的設計根本不能提醒！
如何使行事曆的提醒可以選擇提醒方式它的「頻率」或「選擇提醒的時間長度」？現在的提醒方式振動一下下，聲音也只有短短一秒多，根本就無法執行到提醒的作用，工作因此而受影響。

Many users have multiple Task folders in Outlook (different jobs or projects, etc). Allow tasks to be viewed by folder in Windows Phone.

Combine tasks and flagged e-mail in one view as in Outlook tasks list.

Have the option to set default calendar reminder as none/off. So I don't have to keep turning it off on every appointment I make.

Other people put their vacation as meeting invites on my calendar and it clutters my live tile and lock screen. I would love an option to hide them per calendar.

Month view itching to be pinch-zoomed. Text in the day squares is fake, and could become real when zoomed in.

Full text search across calendars

The one thing holding me back from WP7? No contacts and calendar sync with my Mac

( a meeting for six weeks on Mondays impossible.) either create every single appointment, or to set in on weekly repetition and delete it

The ability to see shared calendars from Google like company calendars

Birthdays of contacts that come from a private exchange account are not shown in the calendar app. Even my Galaxy S3 shows them and that should be a standard functionality in 2012.

Windows 6.5 provided the capability to copy/paste appointments. That option is no longer available with Windows 7.5, which is a HUGE downgrade.

Window 6.5 also allowed repeat or recurring appointments to be setup with an end date or to end after a set number of occurrences. That option is no longer available, which is another HUGE downgrade.

Please restore those functions!

In the Calendar add the option to navigatie to the location of an appointment

Windows Live Mail & Outlook support recurrance options for appointments in the calendar (e.g. "every 2 weeks") which would be useful on WP7.

I suggest putting it as an option straight in the reminder popup notification for easier accessibility (no need to unlock)

Have the colors from my outlook categories sync to the phone. Make outlook calendar sync easily to the phone.

I have placeholders as appointments, or two appointments same time. Having only one at lock screen is useless if the one picked is less important.
