🎉 New! Connect your Outlook calendar to Trello Planner 🗓️

[#1]

Hi Trello Community,

We’re excited to announce a highly requested update: Trello Planner now integrates with Microsoft Outlook Calendar!

In the last four months we’ve seen many utilize the new Planner feature in Trello to drag and drop saved cards from their boards directly onto their synced Google Calendars. This has helped users tremendously with scheduling tasks, setting reminders, and prioritizing important deadlines while balancing logistics for both work projects and personal appointments in a single view.

Now, you can connect your Outlook account and see all your meetings, events, and Trello tasks in one unified view—making it easier than ever to manage your time and get things done.

What’s New?

• Outlook Calendar Integration: Visualize your Outlook meetings and events right alongside your Trello tasks.

• Two-way Sync: Schedule focus time and Trello cards directly from Planner, and see updates reflected instantly in both Trello and Outlook.

• Real-Time Updates: Changes in Outlook or Trello Planner sync automatically, so you’re always up to date.

How to get started

1. Navigate to the new bottom navigation bar at the bottom-center of any of your Trello boards and click “Planner” to open the Planner panel.

2. Once you’ve opened your Planner panel, click on the “Connect a calendar” button and choose the “Outlook calendar” feature

3. Connect your Outlook account securely via OAuth by clicking “Accept”.

4. And vióla—now you can enjoy a seamless, unified planning experience with your Outlook integrated with Trello Planner! Please note: Trello users on paid tiers can schedule and edit tasks onto their synced calendars within Planner. Free Trello users can sync their calendars in “view-only” mode.

📣 We want your feedback!

Hi.

This is fantastic! I have so many Trello cards assigned to me, I love the idea of planning out working through them in my calendar. 

However there's an issue in the authentication flow - at least for our organisation where we use the approvals process for new Azure Enterprise Applications. On clicking to connect a calendar, it prompts the user to request approval for the app - as it should on the first occasion. The admin then approves it. However on second attempt it repeats the same process - always requiring approval (even though it's approved) and never connecting successfully. This is the same regardless of whether the user is manually added to the Azure Enterprise App, whether user assignment is enable or disabled.

After a little digging I can see in the URL that the authentication flow is specifically requesting consent each time it is redirecting to Microsoft, the start of the URL being  https://login.microsoftonline.com/common/oauth2/v2.0/authorize?prompt=consent&access_type=offline&

I have found that if I remove the prompt=consent& part then it connects successfully, but that doesn't scale well for a lot of users. 

I'm not sure how you implement a fix for this of course, but hopefully it helps diagnose the issue!

Hi, I am also trying to connect my outlook to Trello and it says that it connects successfully after connecting with my Microsoft 365 account, but then I can't see anything and it still has the prompt to sync a calendar - any idea how to fix this?

Hello, it's so sad this feature is not useful for me, I don't need to see any agenda inside my Trello board.

Is it possible to come back to the previous view, with more spaces to see Trello lists 🙏?

@Recontact you can easily close Planner if you are not using it:

Every time Trello creates a calendar entry, it shows on my Outlook calendar as Private. Can this be changed?
