What are the disadvantages of Thunderbird email? ›

Complex User Interface: Some users may find Thunderbird's user interface to be complex and difficult to navigate, especially if they are not familiar with advanced email features. Slow Performance: Thunderbird may run slow on older computers, especially when managing a large number of emails and attachments.

With IMAP, emails are stored on the server by default, which could present issues if the server is compromised. However, unlike with POP3, IMAP users do not have to worry about their emails being destroyed if the device they are downloaded on is lost or damaged.

Anything you do to the messages in your local mail client — reply, delete, forward, and so on — is synchronized with the copy on the IMAP server. This allows you to connect to your email account from multiple devices and allows your messages to always stay in sync.
