Understanding Why Microsoft Outlook Calendar Not Syncing

Outlook Calendar sync failures in enterprise environments rarely stem from a single cause. Take a look at the various scenarios that might cause this issue:

• The disk errors or abrupt shutdowns may corrupt the Outlook data file. This makes them unable to process the new updates from the server. 
• Wrong DNS records or blocked firewalls can prevent Microsoft Outlook Calendar from syncing the schedule. 
• Security badges or the stored tokens become old and do not get recognized by Outlook, causing the Outlook calendar to stop updating. 
• A speed limit is predefined for how much data Outlook can pull. If the user exceeds this limit, it throttles the connection, causing Outlook to lag.
• Using the Outlook calendar on multiple devices can create sync conflicts. Also, it generally occurs if the changes are made offline.

Solutions to Fix Outlook Calendar Not Syncing Issue

Now, let us look at the solutions to fix the Outlook sync failure issue. 

Method 01: Check Internet Connection

The synchronization process requires Outlook to get connected to a stable internet connection. If the network is slow or gets disconnected frequently, it can prevent Outlook calendar from syncing properly. Try checking the following points:

• Open any web browser and try to load a website.
• Change from Wi-Fi to mobile data.
• Restart your Router or Modem and try reconnecting it.

Method 02: Update Microsoft Outlook 

If your Outlook application is outdated, it can affect the calendar synchronization. An outdated Outlook may create compatibility issues or contain bugs that can lead to a “Calendar is Not Syncing with Outlook” error.

1. In Windows, open MS Outlook and go to File.
2. Then, click on Office Account > Update Options.
3. Click on the Update Now button if an update is available.
4. Download and install that update. Then, restart MS Outlook.
