You can do the Google Workspace Outlook Configuration. Are you a die-hard fan of the Microsoft Outlook interface but love the reliability and cloud power of Google Workspace (formerly G Suite)? You are not alone. Many professionals prefer Outlook for its robust offline capabilities and familiar layout, even after their company has migrated to Google’s cloud.
The good news is you don’t have to choose. By configuring Google Workspace on Microsoft Outlook, you can get the best of both worlds: Google’s world-class spam filtering and sync speed, wrapped in the Outlook interface you know and love.
At namastu.com, we help businesses bridge this gap daily. Here is your step-by-step guide to setting it up correctly.
Why Not Just Use IMAP?
Before we dive in, a quick technical note. You can set up Google Workspace on Outlook using standard IMAP/POP settings. However, we do not recommend this for business power users.
-
IMAP only syncs emails. It will not sync your Google Calendar or Contacts.
-
GSSMO (Google Workspace Sync for Microsoft Outlook) is the official tool from Google. It creates a complete bridge, syncing your Emails, Calendars, Contacts, and even Notes.
Prerequisites: Before You Start
-
Admin Access: Ensure your Google Workspace Administrator has enabled “Google Workspace Sync for Microsoft Outlook” in the Admin Console (under Apps > Google Workspace > Gmail > End User Access).
-
Outlook Version: You need a compatible version of Outlook (2016, 2019, or Microsoft 365 desktop app).
-
Clean Slate: It is often best to start with a fresh Outlook profile to avoid data conflicts.

Google Workspace Outlook Configuration Steps
Step 1: Download and Install GSSMO
For Windows users, Google provides a dedicated utility that handles the heavy lifting.
-
Close Microsoft Outlook completely.
-
Visit the GSSMO download page and download the .exe file recommended for users.
-
Run the installer. It will verify your internet connection and download the necessary components.
Step 2: Sign In and Authorize
Once the installer finishes, a sign-in window will pop up.
-
Enter your Google Workspace email address (e.g., yourname@company.com).
-
Click Continue.
-
Your default web browser will open, asking you to sign in to your Google account.
-
Review the permissions requested (Gmail, Contacts, Calendar, Drive) and click Allow.
Note: If you are stuck on the “Waiting for authorization” screen, check your browser tabs; the permission window might be hidden behind other windows.
Step 3: Create Your Outlook Profile
After authorisation, the GSSMO tool will ask you to set up your profile.
-
Import data from an existing profile: Uncheck this box to start fresh (recommended for speed). If you need to migrate old PST data, check this box, but be warned: this can take hours depending on your mailbox size.
-
Click Create Profile.
-
Click Start Microsoft Outlook.
Step 4: Let the Sync Begin for Google Workspace Outlook Configuration
Outlook will open, and you will see a small synchronisation status window from Google.
-
Emails: Recent emails will appear quickly, but your full history may take time to download.
-
Calendars & Contacts: These usually sync within a few minutes.
You can now use Outlook normally! Any meeting invite you accept in Outlook will reflect in your Google Calendar, and any email you send via Outlook will be in your Gmail “Sent” folder.
Troubleshooting Common Issues for Google Workspace Outlook Configuration
-
Calendar not syncing? Right-click the GSSMO icon in your Windows system tray and select “View Sync Status” to check for errors.
-
“Limit Exceeded” error? By default, GSSMO limits the local mailbox size (e.g., 1GB or 2GB) to keep Outlook fast. You can increase this limit by right-clicking the GSSMO icon > Set mailbox size limit and choosing “Unlimited” or “4GB”.
