Thunderbird IMAP Offline
You can use the Thunderbird mail client in offline mode with an IMAP email account such as your ITET account.
Click OK and go to File > Offline > Work Offline. You will be asked whether you want to download your messages for offline use. Click Yes. Depending on the amount of data and your internet connection this may take a long time. The status of the synchronization is displayed at the bottom of the thunderbird main window.
You may now disconnect your computer from the internet and write/delete/move messages as you like. Note that when composing a new message there is no longer a Send button. However, there is a Send Later instead.
- Apart from sending new messages, all other changes you made while offline will be synchronized now, lest the IMAP server is up to date. The status of the synchronization is displayed at the bottom of the thunderbird main window.
