How To Fix Google Workspace Sync for Microsoft Outlook Not Working

How To Fix Google Workspace Sync for Microsoft Outlook Not Working

After carefully investigating all the possible causes in a test environment, I’ve created a list of the best remedies below. I’ve arranged the fixes in the order of complexity, starting with the easiest ones.

Perform These Basic System Checks

Make sure that the following are ensured for GWSMO’s successful operation:

Update GWSMO and Outlook

If you haven’t updated these apps recently, it’s a good time to do so now as it might solve your problem.

Navigate to theDownload GWSMO portaland get the latest software package.

Install it on your PC. It’ll replace the existing GWSMO installation.

PressCtrl+Esc+Shiftto bring up theTask Manager.

Below theProcessestab, find the running instance ofMicrosoft Outlook. Click on that to expand its processes tree.

There, you should see theGWSMOprocess in Outlook.

Right-clickand chooseEnd taskfrom the context menu.

Both the Outlook and GWSMO apps will stop running as background services.

You can verify that from the system tray. Normally, when the apps are running, these services would also show up on the system tray.

Now, launch Outlook again for the GWSMO update to become globally effective.

Turn Sync Modules Off and On

When none of the GWSMO modules are syncing to update the content in Outlook, perform these steps to force a sync:

Now, restart Outlook. Ensure you see the following dialog box when relaunching the email client.

It confirms that the email tool is designated to sync content from the Google Workspace profile.

When you land on the mailbox, you should see new contents that weren’t available before due to the GWSMO Outlook not working issue.

Customize the Mailbox Size Value

Microsoft Outlook works smoothly and efficiently when you select a small local file size for the mailbox. This space is used by GWSMO to cache emails from Google Workspace webmail.

Irrespective of the mailbox size you choose for the local directory, GWSMO will import all the emails of your webmail.

If you choose theUnlimited (slowest)option, you’ll also slow down Outlook significantly.

So, click on theWindows System Trayandright-clickon theGoogle Workspace Syncapp.

Now, click on theSet mailbox size limit.

Choose a local mailbox directory size of1 GB,2 GB, or4 GB.

UncheckUnlimited (slowest)if you’ve selected it previously.

Reconfigure GWSMO

Any changes in the Google Workspace email account policy or credentials will immediately impact the integration with its counterpart, Outlook. So, if you suspect some changes might have taken place, follow these steps:

Temporarily Disable Antivirus and Windows Firewall

If your device security system or firewall are inappropriately blocking the GWSMO tool, the following should revert that restriction:

Disabling Windows Security leaves your computer vulnerable, so consider the risks before proceeding. Quickly test if GWSMO is working or not after disabling Windows Security. Once the evaluation is over, enableReal-time protectionagain.

Run Outlook in Safe Mode

The safe mode enables you to run theOutlook appin its default condition without running the add-ins. Here are the steps you can follow:
