Thunderbird duplicate email

The frustration of duplicate emails in Thunderbird!

There are a few ways to deal with duplicate emails in Thunderbird:

1. Use the built-in duplicate detection feature:
   • Go to Tools > Account Settings > Server Settings > Advanced > Duplicate Detection.
   • Enable the "Detect duplicates" option.
   • Set the "Duplicate detection interval" to a value that suits your needs (e.g., 1 minute, 1 hour, etc.).
2. Use a third-party add-on:
   • There are several add-ons available that can help you detect and remove duplicate emails, such as:
     • Duplicate Email Remover (DER)
     • Duplicate Email Detector (DED)
     • Email Duplicate Remover (EDR)
   • Install the add-on and follow its instructions to configure and use it.
3. Use a script:
   • You can write a script using Thunderbird's scripting language (JavaScript) to detect and remove duplicate emails.
   • There are several scripts available online that you can use as a starting point, such as the "Duplicate Email Remover" script.
4. Manually remove duplicates:
   • If you don't want to use any of the above methods, you can manually remove duplicate emails by:
     • Using the "Find" function to search for duplicate emails
     • Using the "Mark as read" or "Move to folder" function to remove the duplicates

To find duplicate emails manually:

1. Go to the "Find" menu and select "Find Messages" (or press Ctrl + Shift + F).
2. In the "Find Messages" dialog box, select the "Subject" field and enter a search term (e.g., " duplicate").
3. Click "Find Now" to search for emails with the specified subject.
4. Review the search results and remove the duplicate emails by marking them as read or moving them to a folder.

Remember to always backup your email data before making any changes to your email client or using scripts to remove duplicate emails.
