Difference B/W OLM and PST and How To Convert OLM Files to PST?

Microsoft Outlook is a popular corporate email software for Outlook.com, Office 365, and Exchange accounts. For Windows, macOS, Android, and iOS, there is an Outlook client. To store mail items such as emails, attachments, contacts, notes, calendar items, and so on, Outlook produces an OST (Offline Storage Table) or PST (Personal Storage Table) file based on the email server on Windows.

Outlook saves mail items in the OLK file format on Mac systems (.olk14Message and olk14MsgSource). However, you may use the import and export options in Outlook on macOS to convert the mail items from OLK to OLM (Outlook for Mac) format.

To back up and move Outlook data from one Outlook profile or a machine to another, both OLM and PST file formats are employed. OLM and PST, on the other hand, are two distinct Outlook data file formats.

We’ll go over the differences between OLM and PST Outlook data file formats, as well as how to use them in different circumstances like mailbox backup and migration, in this article.

Outlook for Mac (OLM)

The OLM file format, also known as Outlook for Mac, is only supported by Outlook for Mac. The OLM file format is used by Outlook for Mac users to back up and migrate their mailbox data between various Mac computers. The Import and Export options in Outlook for Mac may be used to export or import the OLM file.

Personal Storage Table (PST)

Outlook for Mac and Outlook for Windows both support the PST (Personal Folder) file type. It’s the most common Outlook data format for storing, backing up, and migrating mailbox data between Outlook profiles on Windows and Mac.

In Outlook for Mac and Outlook for Windows, OLM and PST files are commonly used to backup and move Outlook mail items. PST is a file format that may be imported into Microsoft Outlook for Windows, Outlook for Mac, Exchange Server, and Office 365. OLM, on the other hand, can only be imported into Outlook for Mac profiles. Furthermore, when exporting Outlook for Mac data to OLM files, you don’t have many choices, which hinders you from exporting or importing certain mail items or account data. Using an OLM to PST converter software, as mentioned in this article, is the preferred method for transferring Outlook for Mac data.

  • After that, you may open your emails by importing this PST file into MS Outlook.

Conclusion

PST is a portable file format that can be imported to Outlook for Windows, Outlook or Mac, Exchange Server, and Office 365. On the other hand, OLM can be imported to Outlook for Mac profiles only.
