Convert OLM to PST File Without Any Attachment Loss

Our new Mac-to-Windows computer will quickly present users with an obstacle they face repeatedly: when the individual migrates email from their Mac-based OLM file to Outlook for Windows, the native tool cannot open it. They must convert OLM to PST File, as any competent IT professional knows. This guide explains the manual method and a professional DRS Softech OLM to PST Converter for a quick and hassle-free process.

What to Check Before Convert OLM File to PST

A few items influence how smooth the process is regardless of the path you later choose:

  • Admin or owner access to both your source Outlook for Mac profile, as well as your Windows Outlook profile.
  • A Gmail account with IMAP access enabled (if the manual route is what you were thinking of).
  • Space to save on your Windows machine, as PST’s sometimes get bigger than the original mailbox due to rebuilt headers, as well as added folder structure.
  • The original OLM file is left on the Mac until you successfully open the PST in Windows Outlook.

Manual Approach to Convert OLM to PST File

In this section, we will discuss the complete steps to do this task manually.

Step 1: Link Gmail to Mac Outlook

  1. Start by opening Outlook on macOS.
  2. Add a Gmail account: Tools > Accounts > Email.
  3. Afterward, enter Gmail credentials and sign in.
  4. Later, create a new folder in Gmail via Outlook.

Step 2: Move Emails from Outlook for Mac to Gmail

  1. In Mac Outlook, drag the desired emails from Outlook.
  2. Afterwards, drop those emails into a new Gmail folder.
  3. After this, Gmail (IMAP) will sync the transferred emails to the cloud.

Note: Make sure IMAP is enabled in your Gmail account. 

Step 3: Configure Gmail in Windows Outlook

  1. First, open Outlook on Windows.
  2. Next, go to File -> Account Settings -> New.
  3. Later, select Manual Setup -> IMAP. 
  4. Further, log in with Gmail credentials.
  5. Once the sync is done, all the emails will appear in Outlook.

Step 4: Convert Emails to PST 

  1. In Windows Outlook, tap File > Open & Export > Import/Export.
  2. Then, choose Export to a file > Outlook Data File (.pst) from the displayed list.
  3. Further, select the Gmail folder with synced emails.
  4. Now, assign the path and tap Finish. 

Limitations of Manual OLM to PST Migration: From the above procedure, it is clear that it has multiple steps, which makes it a lengthy or time-consuming process. Also, there is a high data security risk as data is frequently transferred from one email client to another. If you want a simple and direct approach to complete this process, read further.

Conclusion

The manual method is suitable for a lightweight mailbox but is restricted to an IMAP relay system that was not designed to conserve all the attachments and calendar entries. For those who need to perform OLM to PST file conversion on a heavy or aged mailbox, a product that reads OLM format directly is more effective. One such product is the OLM to PST Converter Tool, which allows you to convert OLM files to PST in a single step.
