Microsoft Exchange Server facilitates the creation of multiple mailboxes that are saved securely in the server and helps the users to commit email management. But, to access these mailboxes, you require an email client that provides a GUI-based appearance to access various folders of a single mailbox account. In the Windows environment, you can use MS Outlook and in the Mac environment, you can install Outlook for Mac.

The functional aspect of both applications remains the same, and the mailbox shows the same types of folders. The biggest difference between both Outlooks is their data file. Windows Outlook creates a PST file and Mac Outlook has OLM file for it. Some significant differences between the data files show their importance and usefulness.

OLM file vs. PST file

MS Outlook for Windows supports two files formats – PST and OST. PST stores data when Outlook is configured with POP3 accounts (however, Outlook stores data in OST files when users work in offline mode with Exchange account). Meanwhile, Outlook for Mac stores data in OLM format. These 2 file formats store all the items of the mailbox, which includes emails, contacts, tasks, events, notes, etc.
