Why SharePoint Calendar Sync to Outlook?

Configuring calendars between SharePoint and Outlook helps users to:

• View SharePoint events and personal meetings in one calendar.
• Check SharePoint events directly in Outlook without needing to open the site.
• Team deadlines are always visible.
• Fewer chances of missing updates or important events.
• Everyone works from the same shared schedule.
• Access events in Outlook even without the internet.

So, these are the common reasons that push users to add calendar from SharePoint to Outlook. Integrating calendars is also part of broader SharePoint document management best practices that improve productivity. Next, I’ll explain the methods to do so.

How to Add SharePoint Calendar to Outlook?

As a Microsoft admin for 15+ years, one thing I learned is how to sync SharePoint calendar with Outlook on your setup. So, let’s have a quick overview of the same:

• Classic SharePoint + Classic Outlook: Use Connect to Outlook (Method 1).
• New Outlook (Windows or Mac): Use Group calendar or Power Automate (Method 3 or 4).
• Outlook on the web: Subscribe using an ICS (iCal) link (Method 2).
• Modern SharePoint Events: Best to use the Group calendar or Power Automate(Method 3 or 4).

Just like keeping a backup of critical data, syncing the calendar ensures nothing is missed, similar to backup SharePoint Online to local storage. If you’re unsure, start with the Group calendar approach, since it works across all clients, i.e.

#Method 1. Add SharePoint Calendar via Microsoft 365 Group Calendar

A Group calendar works in every Outlook client, including desktop, new Outlook, & web, and can be embedded in SharePoint. When you create a Microsoft 365 Group, it automatically gets a shared calendar stored in Outlook (Exchange Online). To sync SharePoint calendar with Outlook, the instructions are as follows:

Steps to Add a Group Calendar to Outlook

• Open Outlook (desktop or web), and click the Calendar view.
• In the left pane, look under Groups.
• Select the Microsoft 365 Group to use.
• Click the group name, then select Calendar.
• The Group calendar opens alongside your personal calendar.
• In Outlook desktop, use the overlay view to see Group events and personal meetings together.

Steps to Add a Group Calendar to SharePoint

• Open the SharePoint site.

• Edit the page where the calendar is to appear.
• Choose the Group Calendar web part from the available options.
• Pick the same group whose calendar you use in Outlook.
• Publish the page. The Group calendar is now displayed directly in SharePoint for all users with access.

Most of the users might think that we’re creating a new calendar, which is wrong. SharePoint doesn’t create a separate calendar; it displays that same Outlook group calendar through the Group Calendar web part. 

So there’s only one calendar, accessible from both Outlook and SharePoint. I hope, now everything is clear about this solution. Let’s move to the next one to add SharePoint calendar to Outlook.

#Method 2. Sync SharePoint Calendar with Outlook (Classic)

If you’re using classic SharePoint calendars and the classic Outlook desktop app, this solution will help you. Here’s how:

1. Open the SharePoint site and go to the calendar.
2. On the top ribbon, select Calendar > Connect & Export group > Connect to Outlook.
3. Allow your browser to open Outlook.
4. Outlook will ask for confirmation. Click Yes.
5. The SharePoint calendar now appears under Other Calendars in Outlook.

If you can’t find the Connect to Outlook option, your site is probably using the modern calendar experience. In that case, try the next method.

#Method 3. Use ICS to Add SharePoint Calendar to Outlook

If you want the calendar in Outlook on the web, the best option is to use an ICS link. For the same:

• Go to the SharePoint calendar to sync SharePoint calendar with Outlook.
• Open Calendar Settings or List Settings.
• Under Permissions and Management, select Connect to Outlook or Export Calendar and copy the ICS link.
• Open the Outlook desktop app.
• Go to File > Account Settings > Internet Calendars > New.
• Paste the ICS link, then click Add > OK.
• The SharePoint calendar appears under Other Calendars in Outlook.

#Method 4. Power Automate Sync

Sometimes I need events to sync automatically. That’s when I use Power Automate to add SharePoint calendar to Outlook:

• Open Power Automate from Microsoft 365.
• Click Create > select Automated cloud flow.
• Set a trigger like When an item is created or modified (SharePoint).
• Choose your SharePoint site and Calendar list.
• Add a new step: select Outlook > Create event (V4).
• Map SharePoint fields, such as Title, Start Time, End Time, Location, Description, to Outlook event fields.
• Save the flow and test by adding an event in SharePoint.

Now, your new events will automatically appear in the Outlook calendar. You can even use this automation to advanced scenarios, like linking SQL database Power Automate flow to SharePoint calendar.

I know, Power Automate requires setup and time, but once you sync SharePoint calendar with Outlook using it, the calendars stay in sync automatically, which reduces manual work. 

Common Problems & Their Fixes

As I experienced in configuration, migration, and backuping up the Microsoft services data, I am aware of where users lack. So, here are some issues faced by users during the synchronisation of SharePoint and Outlook calendars:

#1. Can’t see “Connect to Outlook”

This error usually occurs when you’re on a modern calendar. Switching to classic or using the Group calendar will quickly resolve this. Afterwards, you’ll easily add SharePoint calendar to Outlook.

#2. New Outlook won’t connect

That feature isn’t supported anymore. Use ICS or Group calendar instead.

#3. Events not syncing from Outlook 

Check permissions. You need at least Contribute access to the SharePoint calendar.

#4. Slow calendar load

If the calendar has thousands of events, cleaning it up or using a Group calendar is recommended. You can also check why is SharePoint Online so slow for general performance tips.

So, these are the common issues and solutions where users usually waste time. If you want to make this procedure hassle-free, then follow my best practices. 

Best Practices to Add SharePoint Calendar to Outlook

Remember these points to sync SharePoint calendar with Outlook simply:

• Use Microsoft 365 Group Calendars for modern sites.
• Use ICS or Power Automate only if the group calendar isn’t suitable.
• Don’t mix multiple sync methods for the same calendar.
• Test syncing with a small group first.
• Check SharePoint and Outlook permissions.
• Keep the setup simple to avoid confusion.
