Outlook Calendar

Microsoft Outlook offers a lot of useful features that facilitate management of emails and other tasks. Calendaring is one such useful feature of the email client that allows you to schedule appointments, meetings, etc. When you create a calendar, it gets automatically synced with the server. However, sometimes, you face a situation where Calendar stopped updating. This article will explore the possible reasons behind the Calendar is not updating in Outlook issue and look into the solutions to fix this issue.

Causes of the Outlook “Calendar Stopped Updating” Issue

The primary cause of the problem is incorrect Outlook configuration settings. Besides this, here are some other common causes that can lead to this issue.

  • Outlook client is not connected to the server.
  • System is not connected to the internet.
  • Outlook profile is corrupted.
  • Outlook client is not updated.
  • Calendar entry is corrupted.
  • Inconsistencies or corruption in the Outlook data (OST) file.

Solutions to Fix the Outlook “Calendar Stopped Updating” Issue

Now, let’s look at the possible solutions to fix this problem.

Solution #1: Check the Internet Connection

As a first step, check if your internet connection is stable and working fine. You can open your web browser and then try to open a random website to see if internet is working. If there’s a problem, restart Wi-Fi router or adjust the network adapter settings. If the problem is with your internet connection, contact your Internet Service Provider (ISP).

Solution #2: Update Outlook

If your Outlook version is outdated, it may not be compatible with the latest updates from Microsoft. This can prevent Outlook from syncing calendar entries. To update Outlook to the latest version,

  • Open Outlook and navigate to File > Account.
  • Click on the Update Options.
  • Choose “Update Now” to install the latest updates (if available).Picture 1 41

Solution #3: Analyze the Synchronization Settings

If your Internet is working fine and Outlook is updated to the latest version, then check the synchronization settings in Outlook. To do this, follow the below steps:

  • Open Outlook and navigate to File.
  • Click on Options and navigate to the Advanced tab.Picture 1 42
  • Next, click the “Send/Receive” button under the Send and Receive section.Picture 1 43

  • Next, tick the checkbox labeled – “Include the selected account in this group.”
  • Now, tick the checkbox labeled – “Schedule and automatically send/receive every” and set a proper time.
  • Click OK.

Now, when you open your Outlook, the calendar items will sync automatically.

Solution #4: Delete the Corrupted Calendar Entry or Repair the OST

If Outlook is still unable to update your Calendar, it means one of the Calendar entries is corrupted. If you know the Calendar entry that’s causing the error, simply open Outlook Calendar and delete that entry.

However, if you can’t identify the entry or are unable to delete it, then repair the OST file. For this, use the built-in repair utility, called SCANPST.exe. It is located in C:/Program Files (x86)/Microsoft Office/root/Officexx folder.

Go to the folder and double-click on the SCANPST file. Click Browse to select the OST file and click the Start button to start the repair process. After the repair is complete, restart Outlook and see if this fixes the problem.

Solution #5: Reset the Navigation Pane

Sometimes, incorrect or outdated Outlook settings can prevent Outlook Calendar from updating. In such a case, you can reset the navigation pane. To do this, open the Run utility (press the Windows + R keys). Type “outlook.exe /resetnavpane” and press Enter or click OK.Picture 1 45

This command will automatically reset the navigation pane to its default settings.

Solution #6: Create Outlook Profile

Another possible cause of the Calendar not syncing issue is corrupted profile. In this case, you can create a new profile. Here’s how:

  • Open the Control Panel. Navigate to Mail > Show Profiles > Add.Picture 1 46
  • Give a name to the new Outlook profile and click OK.
  • Next, configure your email account (Exchange, IMAP,, or Microsoft 365). Once done, click Finish.

Now, copy the OST file to a backup location and delete the corrupted profile.

Solution #7: Rebuild the OST File

If none of the above solutions works, it means there are issues with the Outlook data (OST) file. In such a case, you can rebuild your OST file. The steps are as follows:

  • Open Outlook. Right-click on your profile and select “Open File Location”. This will open the location of your OST file.
  • Close Outlook. Move the OST file to a different location or change its extension (to create backup).
  • Start Outlook again. This will create a new OST file at the same location.

Note: After rebuilding the OST file, check if there are any missing emails or other items. If there are any, use an OST to PST converter tool, like Stellar Converter for OST. This is an advanced tool that can help extract mailbox items (missing items) from backup OST file and move them to a PST file. You can then import this PST file into your Outlook profile to restore the missing items.


The Outlook “Calendar stopped updating” issue can occur due to incorrect configuration settings, internet connection issues, outdated Outlook application, corrupted Calendar entry, corrupted Outlook profile, inconsistencies in OST file, etc. Above, we have discussed the solutions to fix the calendar synchronization issue. If there are problems with OST file, then you can rebuild the OST file after taking the backup. If you found any missing items in the new OST file, then use Stellar Converter for OST to extract missing items from the backup OST file and save them to a PST file, which you can easily import into Outlook using Import and Export wizard.
