As you probably know already, the good old Google Calendar Sync program is no longer supported. And I do not think you need to have a third eye to figure out why it has been discontinued. In the fight for leadership and market share, Microsoft and Google are the biggest competitors, and all is fair in love and war… There is no clear reason why users should suffer.

Every Windows 10 operating system installation comes with an email client called the Mail app. Setting up your email with this app is quite easy, it supports most popular email services such as Gmail, Yahoo, iCloud, and others. Although it’s a robust app, there may be some issues that we’ll look at today. In this final episode of our troubleshooting series, we’ll look at the problem of the Windows 10 Mail app not automatically syncing.

What’s causing the problem of Google Calendar/Mail not syncing?

Google Chrome

Google Calendar App For Desktop

You can find the Calendar app in the Start menu if you type calendar in the search box.

The following steps will enable calendar syncing on Windows 10:

Your account has two-factor authentication enabled: If you use two-factor authentication in your Google account, you need to either disable it or create a custom password for the Windows Mail app to get around this issue.

Sync Turned Off In Email App

If your Android device doesn’t sync your emails, you will need to turn off WiFi as well as Power Saving Mode.

Emails Not Syncing

It is possible to fix an out-of-synch email account by tapping the “Refresh All Mail” button on your email client. In this case, your out-of-synch email account will be fixed. 

Failed syncing to your Google Account: In some cases, this issue may be due to a problem integrating your Google Account with your Calendar app.

The app is not allowed to access the calendar: It turns out that a fairly common situation that can cause this behavior in Windows 10 is that the Calendar app is not allowed to sync data due to privacy settings.

Windows 10 Calendar Widget

You will now need to create a shortcut for your calendar app on your desktop by pressing Windows key + R and typing shell:startup. Then you can drag and drop or copy and paste the shortcut into the Startup folder.

Damaged temporary files: Damaged files can also be the cause of this particular syncing issue. Several affected users reported that they were able to resolve the issue by temporarily removing their Google account from the Calendar app and deleting temporary files from the Windows 10 settings menu.

Why Won’t My Emails Update

You may need to contact your IT administrator about a problem with your email server.

Google Calendar App For Windows

For Windows, there is a Google Calendar app called Wavebox, which you can download for free from the Windows Store. Wavebox makes it easy to manage your Google Calendar, since you can view your calendar, create new events, and edit existing events with it. You can also manage your work and personal calendars in one place with Wavebox, since it supports multiple Google accounts.

Damaged Mail and Calendar app installation: According to some affected users, this problem can occur when the local installation of the Mail and Calendar app is damaged.
