Outlook for Mac Corruption – Identity Database and OLM to PST Conversion

There are occasions when Outlook for Mac responds abnormally. It may due to the damage of the identity database of Outlook for Mac. When the identity database is damaged, Outlook for Mac does not open, does not respond or does stop all on a sudden, and you may not be able to open Outlook items as you choose. Outlook message list, Outlook contacts and Outlook contact entries may not be displayed properly. These are all symptoms of the damage to the identity database. The identity database of Outlook for Mac contains all Outlook emails, contacts, calendars, tasks, account settings etc. (You can locate it in the Microsoft User Folder data.) So you need to rebuild the identity database using the Microsoft Database Utility when it is damaged.

Another popular method of dealing with Outlook for Mac corruption is to convert OLM to PST and access them using Outlook for Windows. Outlook for Mac saves its emails, contacts, calendars, tasks, events and other items in OLM format. Outlook for Windows cannot access these files, as it does not recognize OLM format of Outlook for Mac. On the occasions of Outlook for Mac corruption, we can think of converting these files to PST format in order to access them using Outlook for Windows. This is a popular method employed by various Outlook for Mac recovery tools. Also, OLM to PST conversion needs to be done while you are switching over from Mac environment to Windows environment.

OLM Recovery and OLM to PST Conversion

Though Outlook for Mac and Outlook are from Microsoft, they use two different file formats that are not compatible with each other – OLM and PST. Therefore, OLM to PST conversion is necessary when one wants to switch over from Mac to Windows. In addition, it is logically sound to covert OLM to PST files to rescue OLM files after corruption. Some third party tools like Kernel for OLM to PST (free trial version is available) can be tried for this purpose.
