Summary: Outlook Express, a discontinued Microsoft email program, occasionally faces errors like “0x800CCC0B SERVER OR MAILDROP IS BUSY.” This article explores the reasons behind this issue and provides solutions, including data backup and DBX recovery using Kernel for Outlook Express.

Outlook Express, a retired email program by Microsoft available until the Windows Vista Operating System, was succeeded by Windows Mail. Users still relying on Outlook Express should be vigilant about potential errors. While the application typically runs smoothly, occasional errors may arise due to corruption or mismanagement. One example of such an error is:

0x800CCC0B SERVER OR MAILDROP IS BUSY

Reason:

The above mentioned error message appears if the mail server is busy or there is some internal problem with mail server.

Solution:

The 0x800CCC0B SERVER OR MAILDROP IS BUSY message can be resolved in following ways:

  • Try to retrieve emails after some time of receiving error message.
  • If you do not receive emails even after some time (20-30 minute) of receiving error message, contact ISP help desk and confirm that there is no server related problem. If there is any server related problem then wait till that problem is resolved.
  • If server is working well then confirm your account status. If your account has been crashed then create a new user account.

If your account has encountered issues, it’s crucial to back up your current mailbox before creating a new user account. Failure to do so will result in the inability to access emails stored in the current mailbox through the new account, risking data loss. To avoid this, follow these steps to create a backup of your current mailbox:

  1. Select Options in Tools menu in Outlook Express.
  2. Select Maintenance tab.
  3. Click Store Folder button. The Store Folder screen appears.
  4. In the Store Folder screen copy the given location.
  5. Open Windows Explorer, paste the location in Address bar, and press the ENTER key.
  6. The Outlook Express folder containing DBX files appears.
  7. Copy the required DBX file and save it to another location.

After successfully backing up your data, proceed to create a new user account. Once the new account is established, import the backup files to retrieve emails from the old mailbox.
