Export Using Outlook for Mac 2011 on an Older Mac

The most reliable method to recover OLK14 files is to open them in their native environment and export them to a universally supported format.

Because modern versions of Outlook do not support the OLK14 format, your best approach is to utilize an older Mac system that still runs Outlook for Mac 2011.

Once the database is successfully loaded in its native client, the data can be packaged into standard formats that modern applications can easily import.

2
