Email messages that are downloaded from your accounts are always accessible in Zimbra Desktop, even when you are not connected to the Internet. Working in Zimbra Desktop when not connected to the Internet is called "working offline".
When you work offline, Zimbra Desktop cannot access your email accounts, but you can work in Zimbra Desktop as if you were connected to the Internet. You can review your messages, create new messages, clean up folders and make other changes that are synchronized back to your account when you access the Internet the next time.
You can tell if you are working offline if the circle next to your account name is red.
You may be offline before the icon turns red as the network’s status updates when Zimbra Desktop attempts to sync to the server. If the attempt fails, the icon turns red. If your mailbox sync schedule is infrequent or set to check manually, a visual update of the status (green or red), will not be quickly apparent.
You can read your email messages, move them to folders and tag them for follow up.
You can type a reply to a message and send it, forward a message, or create a new message. The messages are saved to the Outbox and when you connect to the Internet the next time, they are automatically sent.
You can delete messages. They are put in the Trash folder and when you connect to the Internet the next time, the messages are moved to the Trash folder in your account. If you emptied your Trash folder, messages are deleted.
You can use the Search and Advanced Search features to find messages and attachments that are in your Zimbra Desktop account.
You can create a search and save it.
You can change your Zimbra Desktop
Options.
These options affect how you work within Zimbra Desktop.
Changing Options in the Zimbra Web Client Desktop, changes your Zimbra
Web Client account options (Preferences) as well.
Changes made in Options for other email accounts affect the Zimbra Desktop
settings only. They do not change your account
settings.
