The best way of migrating Zimbra's TGZ files to Outlook is with the help of dedicated software, such as ToolsGround TGZ Converter. Using the Zimbra Desktop for manual methods is very time-consuming and too complicated and is not recommended when transferring large amounts of data. Using this software will save you time and effort while helping ensure that you do not lose or alter the original formatting of your emails, contacts, calendars, and attachments. Additionally, through the use of bulk TGZ conversion, it preserves the same folder structure that was used in Zimbra Desktop, as well as making it easier for non-technical users and technical users to use. Software is the best way to migrate from Zimbra to Outlook without any problems. It can support all versions of the Windows operating system.
