Zimbra desktop application can connect with multiple account simultaneously and each account will work independently. The Zimbra mailbox will create several folders like emails, contacts, notes, tasks, calendar, briefcase, etc.
In comparison with other email clients, Zimbra has some drawbacks that lower the productivity of an account and compel the user to adopt other email clients or mail servers.
To adopt Microsoft’s email client (MS Outlook), the user should export the Zimbra mailbox to TGZ format and later convert to PST format using a professional software.
