What is the Cannot Delete Message Error in Thunderbird?

Thunderbird can’t delete messages is a common issue that the user gets while using it on their system. When someone is unable to delete messages in Thunderbird, then it may be due to a corrupted Trash folder. This problem is quite irritating and needs to get resolved at the earliest. Also, sometimes Thunderbird may freeze when deleting messages.

What is the reason that causes Thunderbird can’t delete messages error?

After research, I discovered the most common reasons which are as follows-

  • If that file is damaged or corrupted, Thunderbird fails to make these changes and therefore fails to delete a message.
  • When a mailbox is imported into an older version of Thunderbird, or if Thunderbird was not updated for a long period the problem occurs.
  • If the Trash folder gets corrupted for some reason, this may also prevent Thunderbird from being able to delete messages.
