3 Best Ways to Convert Outlook Olm to PST Format

Converting Outlook Olm to Pst format is not exactly a delightful task. It is a very convoluted process that can become quiet painful, leading to data loss and corruption. Nevertheless, it is something that you have to go through if you are switching from Mac to Windows and want to transfer your data.

Olm to Pst conversion is basically required when the data in Mac Outlook needs to be transferred/copied/migrated to Windows Outlook. So this tutorial is essentially about 3 Best Ways to migrate data from Mac Outlook to Windows Outlook.

Now, there are many methods for migrating data between these two clients but not all of them work properly. I have tried almost all of them for myself and for many other, and I have come up with 3 best ways to migrate Outlook data from its Mac variant to Windows'.

#3 – IMAP Enabled Email Account (Preferably Gmail)

Email services like Gmail that are IMAP supported are needed for this method of data transfer.

Here's what you you have to do –

Create a new, dummy email account on Gmail or icloud or any other IMAP enabled email service.
Go to Mac Outlook, on the tools menu, click 'Accounts' > 'Add' > 'Email'.
Enter your emails address and the password for the account you created above.
Drag your emails (the ones you want to convert) to the IMAP account folder. Depending on the number of emails and internet speed, it will take few minutes to sync/upload the data to the servers.

Now, it is time to sync/download this data to your destination client, Windows Outlook. First, you need to add the account to the client.

Click the 'File' tab at top left corner. On the right pane, under 'Account Information', click 'Add Account'.
Enter your name, the Email address and the password (for the account you created at step 1). It might take few minutes for the setup to complete. Click 'Finish' when it is done.
Let Outlook download or sync the emails from the servers.
When it is done, drag the folders to any other local folder.

And this is how it is done. You basically used an email account as an intermediary to transfer data from Mac Outlook to Windows Outlook. You also didn't use any data file like Olm or Pst.

The major benefit of this technique is that it is free and there is no need to install any third party tool. Other than that, it is not a viable solution in case of large database due to many other issues like incomplete migration, slow, tedious, and lengthy. It also uses a lot of internet usage

#1 – The Best Method for Data Migration is using “Olm to Pst Converter Ultimate”

“Olm to Pst Converter Ultimate” is an advanced version of “Olm to Pst Converter Pro”. But saying it is an 'advanced' version is not fair considering what it can do. Considering its features, it is a completely different software that allows data migration in totally new way.

So, the “Olm to Pst Converter Ultimate” can load your database of Mac Outlook from the identity folder in Mac automatically. That means, the first half of #2 method is not necessary. You don't need to archive data to Olm file at all. The tool will pick up and scan the Outlook folder and convert to Pst files from there.

It brings excellent aspects to the conversion results. The converted Pst files will be more accurate, the rate of conversion is much faster, and performing the task becomes intuitive. Everything gets simpler and more efficient.

Converting Mac Outlook to Windows Outlook has always been challenging enough for people to go insane. Many of us tend to go towards cheap or even free methods without realizing their actual cost in terms of time and productivity and the safety of our data. Looking at bigger picture, all the manual methods or freeware turn out to be more costly.
