How to Migrate from Outlook to Google Workspace

How to Migrate from Outlook to Google Workspace

Google Workspace is a must-have productivity and collaboration tool for businesses, offering a wide array of features. Microsoft has its own alternative in Outlook, but it is not as sophisticated as Google’s offering. If you are frustrated with Outlook and want a better experience, follow this guide to migrate to Google Workspace.

During the migration process, you must save an Outlook PST file. The GWMMO tool (Google Workspace Migration for Microsoft Outlook) only works for writable PST files, not read-only ones. At the same time, the tool doesn’t consider removing duplicates while migrating. If you have Outlook notes and RSS feeds, you might have trouble migrating them to Google Workspace.

You can sync Outlook with Gmail if you just use Google’s email service.

1. Setting up a Google Workspace Account

You will first need to have a functioning Google Workspace account where you will move your files.

Backup Before Migration

If you are willing to accelerate your productivity and enhance your efficiency at work, consider migrating to Google Workspace and enjoy its perks and benefits.

That said, ensure you have a backup of all files and plan if you need to revert to Outlook.
