outlooktozcs-banner-enHello, Everyone. On today’s blog I will answer the frequently asked question: How can I import a .pst file into my Zimbra Desktop?

The answer is with the new Zimbra Migration Tool, included in Zimbra Collaboration 8.7 and above.

It doesn’t even need an installation, just extract and execute!

Identifying the .pst file to Import into Zimbra Desktop

To identify the .pst file to import into Zimbra Desktop, go to Control Panel > Mail > click Properties > click Data Files > and you will see the Location.

Then select the second option called Export to a file.

outlooktozcs-003Select the second option called Outlook Data File (.pst).

outlooktozcs-004Click on the Top Account name and be sure you have selected Include subfolders.

outlooktozcs-005Finally, select the location where you want to save the .pst file. It will ask for a password at the end. Add one if you want to increase the security.
