Microsoft Outlook

  • Some people want to make subfolders in Outlook to organize their email. However, these folders are not store in the server. Instead, they are stored in the Outlook. If you delete an email account or uninstall Outlook, make sure that you make a backup, export the information to an Outlook Data File (.pst).
  • If you want to migrate Outlook messages, contacts, calendar, tasks, notes, and subfolders from one computer to another or restore a backup of your Outlook data, Import and Export is the easiest way to complete the task. When you export, make sure that the Include subfolders box is checked so everything in your account, including mail, calendar, contacts, tasks, notes, and subfolders are exported.
  • When you use Outlook, your email messages, calendar items, tasks, subfolders, and other items are saved on your computer. Outlook items that are saved on your computer are kept in Outlook Data Files (.pst). You can use that file to restore your email on your computer. The fastest way to open the folder where your Outlook Data file (.pst) is saved is to do the following:
    1. In Outlook, click the File tab.
    2. Click Account Settings, and then click Account Settings.
    3. On the Data Files tab, click an entry, and then click Open Folder Location: \Users\user\AppData\Local\Microsoft\Outlook.

    Go to Settings -> Disable Updates Manager to configure your settings.
    Alternatively, you can disable automatic updates in WordPress by adding this line of code in your wp-config.php file:
    define( 'WP_AUTO_UPDATE_CORE', false );
