Convert OLM to PST Manually – An Easy Step-by-Step Guide

olm to pstIn this post, we’ll discuss how to convert OLM to PST format manually. While switching from one email client to another, email conversion becomes a vital need. The Outlook for Mac and Windows Outlook don’t support same file formats. If you’re planning to switch from Mac Outlook to Windows Outlook, you must convert convert OLM to PST format.

Microsoft provides its Outlook application not only for Windows system but also for Mac or Macintosh machine. Microsoft Office Outlook 2011 for Mac is pretty similar to the Windows MS Outlook program. The only difference between them is the data files used by these programs to store mailbox data. You are quite familiar with PST or personal storage table, an Outlook data file of Windows Outlook. But do you know in which format Outlook for Mac stores the mailbox data? Well, the answer is OLM (Outlook for Mac) file in which your mailbox data are stored by Outlook for Mac.

But remember one thing, you cannot open an OLM file in any version of Windows Outlook as Windows Outlook only understands PST format. Even you should not try to import the files manually if you do not have sound knowledge. Importing the OLM files to Windows Outlook in a wrong way may cause corruption in the OLM files. In this blog, you’ll come to know how to import an OLM file to Windows Outlook in a safe manner, i.e. without causing any damage or data loss.

Need for OLM to PST conversion

Before I discuss how to import OLM to Outlook, I would like to tell you the reasons behind this need. I mean why we need to import OLM to Windows Outlook.

  • You were using Outlook for Mac previously, but now you’re using Windows Outlook. You need to use OLM files in your Windows Outlook. What will you do?
  • Or, You receive an OLM file from your friend or a client. You’re unable to view the content and information of the file since you don’t have Outlook for Mac.

Sometimes, you need to convert OLM to PST format due to any reason. The best solution one can try is professional OLM to PST Converter software. But before using any such paid solution, you should try an easy manual trick to import OLM to Windows Outlook. How? First, you need to set up an IMAP (Internet Message Access Protocol) mail account. This will help you transfer email messages and other content from Mac Outlook to Windows Outlook.

Simple Way to Setup IMAP Email Account

It’s very simple to create or set up an IMAP account, i.e. it only requires 3 easy steps. Gmail would be an ideal option for creating or setting up an IMAP Mail account. So you can start this process with the creation of an email account in Gmail. Once the account is created, just log into it and follow the steps given below:

Step 1: Click the Gear button at the top on the right side. Click Settings to go to the settings page.

Step 2: At the settings page, click Forwarding and POP/IMAP tab at the top.

Step 3: Check your IMAP status. If it’s disabled, enable it and click Save Changes button.

This will create an IMAP mail account. Now you need to setup Mac Outlook with your IMAP mail account.

Follow the steps given below to do this action:

Step 1: First, open Outlook for Mac. On the main menu, go to Tools > Accounts.

Step 2: On the accounts page, click Email.

Step 3: Now you need to enter your account information. Type your Email address, Password, and other information. Click Add Account button.

Step 4: This will successfully add the IMAP mail account, and you’ll see your IMAP mail account on the Mail tab.

After this, you need to create a Gmail label to synchronize it with the Mac Outlook. To do this, just follow the steps given below:

Step 1: Login to your Gmail account. Click the Gear button which you will see on the top at the right side.

Step 2: A list will be scrolled down. Click Settings to go to the settings page.

Step 3: On the settings page, click Labels tab at the top.

Step 4: You need to create a new label. To do this, click Create new label button.

Note: Make sure the label is shown and the Show in IMAP box is checked.

Step 5: Right after this, you need to go to your Mac Outlook and update the IMAP mailbox by clicking on the Send/Receive button.

Move Emails from Mac Outlook to IMAP Mailbox

It is the main part of this process in which your emails and other mailbox data of an OLM file will be moved or transferred to your IMAP mailbox. Follow the steps shown below:

Step 1: First, launch Outlook for Mac on your system.

Step 2: Right-click any mailbox item that you want to move. Click Move > Copy to Folder.

Step 3: Now type the name of your IMAP folder and click Copy.

Step 4: After copying the selected mailbox data to IMAP mailbox, you need to update your Mac Outlook IMAP folder by clicking Send/Receive button. Or you may also update it by refreshing the folder on Gmail.

Now you can see all the copied emails or other mailbox data have been synchronized to the IMAP mailbox folder.

Now you need to move all the emails or other mailbox data from the IMAP mailbox folder to Windows Outlook. You need to set up the very same IMAP Mail account to the Windows Outlook. Now drag your IMAP mailbox folder data to your Windows Outlook Inbox Folder.

Few drawbacks of this manual solution: 

  • Little risky (take backup of your OLM files before using this solution);
  • Time-consuming;
  • Requires a sound technical knowledge;
  • Ineffective if OLM files are corrupt; etc.

These are few common drawbacks of this manual solution of importing OLM data from Mac Outlook to Windows Outlook. There’s one of more solution which you can use: a professional tool for converting OLM to PST format.

  1. It is truly a nice and helpful piece of info. I am happy that you shared this helpful info with us. Please stay us informed like this. Thanks for sharing.

  2. Thank you very much for this guide!
    One question though, if I now remove the Gmail-account from the Outlook on Mac, will it remove the labels in Gmail? Should I toggle ‘Show in IMAP’ before doing so?

    I’m sorry I’m new to this, help is much appreciated!

    Thanks in advance!

  3. Any ideas on how I get contacts and calendar items from Outlook for Mac 2011 (running on Mac Book Air) into gmail? It won’t sync with i cal and contacts?

  4. Many thanks for this… Unfortunately It doesn’t work at step “Move > Copy to Folder”.
    Outlook never finds the target folder to copy data into… 🙁
    Any idea ?

  5. Thank you very much. Your instructions were clear and easy to follow. Everything worked first time. Your blog is now my go-to sight for fixing data recovery & email management issues.

  6. What can I do if I have already the OLM files as a backup in the hard drive? I don’t have access to the Mac outlook anymore.

    1. Dear Angelica, it would be difficult if you don’t have access to the Mac Outlook now. To perform the manual trick, you must have access to your Outlook for Mac. If it wouldn’t be possible to get re-access to the Mac Outlook, then you can try the third-party OLM to PST Converter tool mentioned in the post. Or give me some time to work on your issue.


  7. Hi, Any luck on your last comment, I also have the same situation of not having access to Mac Outlook and have the files stored on my hard drive.


    1. Dear Prashant, if you are not having access to your Outlook for Mac but OLM files are still there in your hard disk drive, you have better chance to convert them into Outlook PST format using the advanced OLM to PST Converter tool mentioned in the blog post. Try it one.


  8. Thanks for the steps.. Worked like magic 😉 . Just wanted to add that when creating an email for Gmail, you need to make sure Less secure apps option is turned on. I actually got an email that asked if I wanted to access less secure apps. So keep an eye on your email in case, the outlook authentication for email fails.

    Hope this helps!
