如何讓Outlook 2010桌面通知顯示超過30秒...

Outlook 2010桌面通知

檔案 --> 選項 --> 郵件 -->桌面通知設定 -->桌面通知將出現多久?

這裡最長只到30秒，如果我們想要讓桌面通知出現更久的時間，要怎麼設定呢???
解法：只要增加一組registry key即可達成延長桌面通知出現的時間，最長可設定出現約50天。

Key: HKEY_CURRENT_USER\Software\Microsoft\Office\\Common\DesktopAlerts
Value name: TimeOn
Value type: REG_DWORD
Value: 0 - 4294964295 

outlook 2010的version = 14.0

以下是參考網址：http://www.howto-outlook.com/howto/newmailalert.htm 之詳細說明：

Display the Mail Alert for longer than 30 seconds; even permanent!

Well permanent isn’t actually possible but how does 50 days sound? Through the Registry you can set the New Mail Desktop Alert as long as 4,294,967,295 milliseconds ≈ 50 days.

Note:
When you use Outlook 2013 on Windows 8, customizing the new mail alert duration works a bit differently as described below as these alerts are controlled by another notification mechanism which is specific to Windows 8. For more info about this see:
Increase the New Mail Desktop Alert duration for Outlook 2013 on Windows 8

Just a little math first to clarify the working of the registry key;

• The value is defined in milliseconds.
• When the registry key is set to 0 the New Mail Alert still shows for 3 seconds so this is hard coded in the program thus 3,000 milliseconds.
• 4,294,967,295 is the maximum value you can set a 32bit DWORD value to in the Registry.
• As the object that controls the time of the New Mail Desktop Alert is also defined as a DWORD and is 3000 already we cannot give the TimeOn registry key a higher value than;
  4,294,967,295 – 3000 = 4,294,964,295
• To convert from milliseconds to days, we must divide the milliseconds through; 1000 to convert to seconds, then 60 to convert to minutes, then 60 to convert to hours, then 24 to convert to days
  (4,294,964,295 + 3,000) / (1000 * 60 * 60 *24) ≈ 50

After all this math it’s time to tell which Registry value controls all this:

Key: HKEY_CURRENT_USER\Software\Microsoft\Office\\Common\DesktopAlerts
Value name: TimeOn
Value type: REG_DWORD
Value: 0 - 4294964295 

If this key isn’t available choose Edit-> New-> DWORD Value and name it TimeOn(case sensitive!).

Double click the key to give it a decimal value between 0 and 4294964295 (in Hexadecimal value this will be fffff448).

Setting the maximum decimal TimeOn value in the Registry.
