How to Move OLM Files to Google Workspace?

Whether you are performing a company-wide migration, refreshing devices, handling M&A, divestitures, or meeting compliance and archival needs, you need appropriate solutions. This guide explains a free drag and drop method or the professional OLM Converter to make the import. Find out the detailed stepwise procedures below.

Manually Import OLM Emails to Google Workspace

The method is free and uses only your existing email applications to make the import. The steps to follow are:

Get started by launching your Outlook for Mac.
Then, go to File and choose Import to add OLM.
Pick the OLM file from Mac and tap Import to load.
Further, move to Preferences and click Accounts.
There, choose to add a new account via IMAP.
After that, enter your Google Workspace credentials.
Authenticate your account and create a folder in it.
Later, under On My Computer, find your OLM files.
Drag and drop them into the Workspace folders.
Finally, wait until all the data synchronizes and is accessible.

Drawbacks of the Method

Works only for a few folders, difficult if the mailbox size expands.
Consistent sync interruptions and slow uploads.
Duplicacy and inconsistency in mapping folders.
Failures in uploading attachments, contacts, and calendars.
Time consumption is high with large and bulky multiple emails.
Need admin credentials and internet to sync the accounts.

Professionally Import OLM to Google Workspace

If you have a massive dataset of the OLM emails that you want to batch migrate for multiple accounts, then use the OLM to PST Migration Tool for Windows. This software handles extreme enterprise-grade datasets with 100% accuracy and zero data loss. It uses secure authentication via admin ID and JSON key uploads. You can import Outlook OLM to Gmail (Workspace) with advanced filtering via date range, duplicates, and attachments, and ensure that you save data either into the default folders or as per the tree hierarchy precisely.

Working Process to Migrate OLM to Google Workspace

Launch the OLM Converter Software and click Add File/Folder.
Then, choose the OLM to upload, select it, and click Proceed.
Further, preview the email contents to finally select and tap Proceed.
Afterward, choose Google Workspace, enter credentials, and authenticate. Pick ID and tap Proceed.
In the end, select the filters to apply before importing and click Start Export.

Real Scenario:

A marketing firm with 250 employees is transitioning from the Outlook for Mac email client to Google Workspace. Every employee has an estimated 8.5 GB of mailbox data stored in their respective OLM archives. The process of using a manual sync to complete the migration could take a significant amount of time, due to:

Individual imports of each employee’s mailbox
Individual configurations of each employee’s account
Ongoing monitoring of the sync every time a process runs.

The project team may need to spend weeks confirming the accuracy of the transferred data before moving to Google Workspace. Whereas, using a dedicated OLM Migrator will speed up the transfer of mailboxes from Outlook for Mac to Google Workspace, as well as retain folder structure and ultimately decrease the duration of the entire project while maintaining 100% accuracy of every employee’s mailbox. Even you can run pilot tests before the actual migration with the Demo version of the software for a risk-free experience.

Final Remarks

Nowadays, organizations are more focused on ensuring data integrity, secure migration, and no loss instead of simply moving mailboxes. Therefore, when you import OLM to Google Workspace, choosing an authentic solution is necessary to facilitate a hassle-free migration. Manual method may suffice for a few emails but with enterprise level mailboxes, you need proper OLM to Google Workspace Migrator which is scalable, reliable, and supports a flawless conversion for large datasets. The only key to preserve the business value and continued operations is opting for a smart solution.
