Consider the following scenario:

You try to transfer data from the Microsoft Outlook for Mac 2011 client, such as email and contacts, to the Microsoft Outlook client. To do this, you try to import an .olm file. However, you receive the following error:

The file <path>.olm is not an Outlook data file (.pst).


Microsoft Outlook for Windows does not support .olm data files. However, there are several methods that you can use to transfer data from Outlook for Mac 2011 to a Windows-based Outlook client. These methods require that you use Microsoft Exchange Server.

Synchronize data with Microsoft Exchange Server
If the data is available in a mailbox that is located on an Exchange Server, the Outlook for Windows client can access the data. To do this, the Windows client connects to the Exchange Server by using either Cached Exchange Mode or Online mode.

Export data from Microsoft Exchange to an Outlook data (.pst) file
Use the Export-Mailbox shell cmdlet from Microsoft Exchange PowerShell to export mailbox data to an Outlook data (.pst) file. For more information about the Export-Mailbox shell cmdlet, visit the following Microsoft websites:

Note Currently, Microsoft does not have a utility to convert an .olm file to a .pst file.
