Gmail Not Syncing With Outlook

Last updated on August 11th, 2025 at 3:48 pm

When your company can utilize Microsoft products such as Outlook but also choose to use Gmail, there is no better option than to sync both. Are you facing difficulties in conducting Gmail and Outlook synchronization? Or, do you face the “Outlook 365 not syncing with Gmail” issue? You may experience difficulties synchronizing some or all data.

The problem can affect only contacts while deleting emails when transferring messages across folders, or all parts of accounts. Since no official solution has been announced, some solutions are available to resolve the issue. So, here are some of the best approaches to tackle the synchronization issues.

Reasons Why Outlook Doesn’t Sync with Gmail

While we begin any action, we must first understand why Outlook 365 not syncing with Gmail. So, here are some topics relating to this issue in the following paragraphs:

  • Windows upgrades often can prevent the IMAP connection from working.
  • Outlook folder reorganization.
  • A faulty network connection may prevent Outlook from syncing with Gmail.
  • Outlook’s PST size limitation prevents synchronization at one point.
  • Incorrect Google account settings might be a factor influencing synchronization.
  • Owing to a corrupted data file.

Best Ways to Tackle the Syncing Issues with Gmail and Outlook

We have listed a few solutions that will assist you in fixing the Outlook 365 not syncing with the Gmail issue. Read about all the methods carefully and understand the best ways to tackle the problem.

Method 1. Avoid Using the Google Sync Service Available for Free

Google Calendar Sync and Google Sync were initially designed for syncing your   Gmail Account with the Outlook accounts. These services, unfortunately, are no longer accessible because Google stopped them in 2012.

As a result, this service now solely impacts free syncing with Outlook. Several organizations with a subscription Google Apps account can continue to utilize the premium syncing service while certain difficulties persist. People who rely on premium syncing services will not confront such problems.

Method 2. Look if There Is Any Faulty Windows Update Available

If you notice the “Outlook 365 not syncing with Gmail” issue, you should verify the Windows updates running on your computer. Some erroneous or undesired upgrades might cause this problem. Like KB2837618 and KB2837643, some updates prohibit IMAP folders from syncing properly.

For syncing with Gmail, Outlook should be set to utilize IMAP. For re-syncing your accounts, you will have to remove these unwanted updates. Microsoft recommends delaying the upgrade as much as necessary until the problem is rectified and a new version is available.

Method 3. Reset Your Outlook Account

If you are facing the error and thinking about how to get rid of it, reset your Outlook accounts and get the best outcomes. Following are the best possible steps that can help reset your Outlook account.

Step 1: You need to open your Outlook account.

Step 2: You need to look for the “File” option and click on the “Add account” option.

Step 3: Here, you need to type your credentials that follow your email address, name, and password. Once you enter all the details, hit the “sign-in” option.

Step 4: Lastly, you need to add an email account and hit the “connect” option.

Method 4: Verify Your Gmail POP and Gmail IMAP Server settings

For IMAP Server Settings:

IMAP enables users to read their Gmail messages in some other emails, including Outlook 365. This can be used in several systems in real time. You need to follow the below procedures to make sure that the IMAP is enabled in your Gmail account:

Step 1: You need to open your Gmail account and click the settings option present on the top right side of the screen. Then, select the “See All Settings” option.

Step 3: You will have to hit on the “Forwarding and POP/IMAP” tab.

Step 4: Following this, choose the “Enable IMAP” option in the “IMAP Access” and then hit on the “Save Changes” option.

Step 5: After the IMAP settings, you will have to alter the SMTP and other configurations in Outlook. Follow the below table and set your settings accordingly:

Incoming Mail (IMAP) ServerImap.gmail.com Requires SSL: Yes Port: 993
Outgoing Mail (SMTP) ServerSmtp.gmail.com Requires SSL: Yes Requires TLS: Yes (if there) Requires Authentication: Yes Port for SSL: 465 Port for TLS/START TLS: 587
Display Name or Full NameUser’s name
Account Name, User Name, or Email AddressUser’s email
PasswordUser’s Gmail Password

For POP Server Settings

Once you are done with the IMAP settings, you need to do the same thing with the POP server setting. POP also performs a similar function as the IMAP settings. The only difference is that POP serves only one system. It does not enable you to sync email in real time, but you can download it and decide the download frequency. The steps to configure the POP settings to download it are:

Step 1: You need to open your Gmail account and click the settings option present on the top right side of the screen. Then, select the “See All Settings” option.

Step 2: You will have to hit on the “Forwarding and POP/IMAP” tab.

Step 3:  Following this, choose the “Enable POP for mail that arrives from now” or “Enable POP for all mail” option in the “POP Download” and then hit on the “Save Changes” option.

Step 4: Lastly, enter the incoming and outgoing mail server settings in your Outlook account as below:

Incoming Mail (POP) Serverpop.gmail.com Requires SSL: Yes Port: 995
Outgoing Mail (SMTP) ServerSmtp.gmail.com Requires SSL: Yes Requires TLS: Yes (if there) Requires Authentication: Yes Port for TLS/START TLS: 587
Server TimeoutsGreater than 1 minute
Display Name or Full NameUser’s name
Account Name, User Name, or Email AddressUser’s email
PasswordUser’s Gmail Password

Method 5. Uses Premium Gmail Account

If you attempt to use the free “Gmail to sync with Outlook” version, the error can occur as Google does not support Google sync now. Whereas Outlook can sync with IMAP, subscribing to a premium Google Apps subscription will provide you with direct syncing options through Google. It aids in avoiding some of the problems that several users are experiencing with Outlook and IMAP.

Method 6: Check the Network Connection

Are Outlook and Gmail not syncing? Well, Outlook’s failure to sync with Gmail may be attributed to a weak network connection. When your Internet connection is not robust, Google prevents Outlook-Gmail syncing. To address this, make sure you’re connected to a stable network and verify that your network settings do not hinder the synchronization process.

In addition to a strong network connection, it’s essential to check for any firewall or security software that might be blocking the sync. Adjust the settings accordingly to allow the necessary communication between Outlook and Gmail. Furthermore, ensure that your Gmail account settings permit access to third-party apps like Outlook for syncing to occur smoothly.

Method 7: Remove and Re-Add Your Gmail Account

Occasionally, despite adjusting settings and troubleshooting, the most efficient solution to resolve syncing issues is by removing and then re-adding the Gmail account in Outlook. Rest assured, this process won’t result in data loss as your emails are stored on Google’s servers, not your local computer. 

Remove and Re-Add Your Gmail Account

To proceed, access Outlook’s “File,” navigate to “Account and Social Settings,” and select “Account Settings” to delete and subsequently re-add your Gmail account for a seamless syncing experience.

By deleting and re-adding the Gmail account, you can create a fresh connection between Outlook and Google’s servers, potentially resolving any sync hiccups. This straightforward approach often helps overcome complexities that arise from conflicting configurations. Remember to have your Gmail account login credentials handy to quickly set up the account again after removal.

Method 8: Repair Outlook Data File

Still, stuck with the “Gmail not syncing with Outlook” issue? Well, you have another valuable option at your disposal – the “Inbox Repair Tool,” also known as “scanpst.exe.” This indispensable tool is an integral part of Outlook’s toolkit, designed specifically to address data file corruption and inconsistencies that could be hindering the syncing process.

To initiate the repair process with the Inbox Repair Tool, follow these steps:

Step 1: Close Outlook to ensure no active processes are accessing the data file.

Step 2:  Locate the “scanpst.exe” tool on your computer. Its default location varies depending on the version of Outlook and the operating system, but you can usually find it in the “Office” or “Outlook” program folder.

Step 3: Double-click on “scanpst.exe” to launch the tool. A small window will appear, prompting you to browse and select the Outlook data file you wish to repair. The data file has a “.pst” extension and is usually named “Outlook.pst.”

Step 4: Once you have selected the data file, click on the “Start” button to initiate the scanning and repair process. The tool will meticulously analyze the file’s structure, searching for any errors or inconsistencies.

Step 5: If the tool detects any issues, it will present you with a summary of the problems found. Click on the “Repair” button to commence the repair process.

Step 6: The repair process might take some time, depending on the size and complexity of the data file. Be patient and allow the tool to complete its task.

Step 8: Finally, open Outlook again and verify if the syncing issue has been resolved. The repaired data file should now function optimally, enabling seamless synchronization with your Gmail account.

It’s essential to keep in mind that the Inbox Repair Tool might not be able to repair severely damaged or heavily corrupted data files. In such cases, consider restoring from a backup or consulting professional IT services to salvage your data.
