When you click an email link in Adobe Reader XI, your Windows 8.1 computer automatically opens its default email application. While this can be a handy time-saver, it can also be a pain if the email app that opens isn't the one you want to use. Take advantage of the Preferences panel in Adobe Reader or the Defaults section of your computer's PC Settings screen to change the default email client that opens when you click email links in Adobe Reader.
Changing the Email Client in Adobe Reader
Click "Edit" on the main menu in Adobe Reader and select "Preferences" to open the Preferences panel.
Select "Internet" from the left side of the Preferences panel and then click the "Internet Settings" button near the bottom in the right pane.
Click "Programs," select "Email" and then choose the application you want to assign as the default email client for Adobe Reader. Click "OK" to save your changes.
Changing the Default Email Client in Windows PC Settings
Swipe your mouse pointer to the top-right corner of your screen, select "Settings" and click "Change PC Settings."
Click "Search and apps" and then select "Defaults" to open the Defaults page. This is the page on which you set the default programs associated with all content types on your computer.
Click the existing default application displayed under the Email heading and then select a new one from the list of compatible programs currently installed on your computer.
If there is no default app set when you first load the Defaults page, click the "Choose a default" link under the Email heading and then select your desired application.
The default email client you select must run locally on your computer. You can’t use a Web-based platform such as Yahoo, Gmail or Outlook.com, for example. In Windows 8.1, the Mail app is often assigned as the default. You can also use programs such as Microsoft Outlook and Mozilla Thunderbird.
On computers running Windows 8.1, you can open the PC Settings screen using the Start button as well. Click the “Start” button, enter “PC Settings” in the Search field and then click “PC Settings” from the search results.
If you use your Adobe ID with Adobe Reader and want to change the email address associated with it, visit the Adobe website (link in Resources). Click the “Sign In” button in the top-right corner and sign in with the existing email address and password associated with your Adobe ID. If you can’t remember your password, click the “Forgot password” link and follow the prompts to reset it. Once you've logged in, click your username in the top-right corner and select “My Information” to display information associated with your Adobe ID. Enter the new email address in the provided field and click “Save My Changes” when you are finished.
