Mozilla Thunderbird is the email client from Mozilla group. Like any other email client, it has many limitations like a limited folder size, attachment size, and number of accounts. When the accounts reach to their maximum size, then the email communication will also stop. So, you can back up the existing account and make more space for the new data.
Also, there is a constant threat of hardware or software malfunction that can corrupt the data file of Thunderbird and delete all the account. So, taking a backup is always beneficial for any Thunderbird user. You can also export the emails to a hard drive and save it on a different computer.
