Analyzing the OLM to PST Issues

Email client users nowadays are much more conscious about backing up their data, especially when they handle critical data through the email. If you are an Outlook for Mac user, you can back up the OLM data in different ways. Here we will have a look at why you need to backup OLM file and how to do it.

Benefits of backing up Outlook for Mac Data File (OLM)

  • A good backup helps to restore data after OLM file corruption; also it protects OLM data against Outlook for Mac errors.
  • It helps to transfer data (all the data or only the required data) from one Mac system to another.
  • OLM data, when converted to a different format (like PST), is accessible in a different environment (like Windows & MS Outlook).
  • Archiving the OLM data reduces the size of the inbox, and enhances the Outlook for Mac performance.

Backup OLM files

Outlook for Mac Data files can be backed up in different ways.

  • Export by item type

The Export feature (accessible from the File menu) of Outlook for Mac helps to export Mail, Contacts, Calendar, Tasks, and Notes to another location. Here, you can choose to delete or not to delete the (exported) items from Outlook for Mac.

  • Export individual items

From the Outlook for Mac item list, one can drag and drop one or more items to desktop or to another folder (use Finder). In this case, messages are exported as EML files, calendar events/tasks as ICS files, contacts as VCF files, and notes as HTML files.

Can the OLM backups be used in Windows environment?

Quite often it is necessary to access OLM data in Windows environment. But when the export method is used, the data is backed up in the OLM format itself. MS Outlook, the Microsoft email client for Windows environment, cannot open OLM files (unless converted to PST format), and Outlook for Mac does not have an option to Export OLM files to PST. So the best option here is to use third-party tool like Kernel for OLM to PST.

Kernel for OLM to PST converts OLM files to PST and makes Outlook for Mac emails accessible in Windows environment (using MS Outlook). Also, this tool helps to save emails directly in Office 365, Exchange Server, and many other destinations/formats.
