When updating a Teams event using the API, if the event already has a virtual meeting (Teams meeting link) and the update request removes the virtual meeting, here’s what might be happening and how to address it:

I am using the Microsoft Teams API to create, update, and delete meetings. However, when I try to update a meeting, it removes the virtual meeting (the Teams meeting link). I am sending the parameter "isOnlineMeeting": true in the request, but the response still returns "isOnlineMeeting": false. I’ve tried everything, and it keeps happening. I need help!

Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!

When updating a Teams event using the Microsoft Graph API, if you are attempting to remove the virtual meeting by setting "isOnlineMeeting": false, it is important to note that once a meeting is enabled as an online meeting, you cannot change the onlineMeetingProvider property or set isOnlineMeeting to false. This means that if the event already has a virtual meeting link, the API will not allow you to remove it by simply updating the event with the same parameters.

As mentioned in this documentation the recommendation is that supply only the values for properties that should be updated in the request body. Existing properties that are not included in the request body will maintain their previous values or be recalculated based on changes to other property values.

I hope this information helps. Please do let us know if you have any further queries.

Hello Julian Lopez,

Thank you for reaching out to Microsoft Support!

For your question, the document provides relevant information.

If the updated event has been enabled as an online meeting, obtain the meeting body first and ensure that the meeting blob is preserved for online meeting when updating the meeting.

Hope this helps.

Hello, I saw that the body stores a link to the virtual meeting, and if I keep it, the meeting is not lost. However, I find it strange that this needs to be kept in the body, as I saw it more as a description.

// Get the existing event Map<String, Object> currentEventDetails = webClient.get() .uri(uriBuilder -> uriBuilder .path("/users/{userEmail}/calendar/events/{eventId}") .build(organizerEmail, eventId)) .retrieve() .bodyToMono(Map.class) .block(); // Extract the current body if it exists String existingBody = null; if (currentEventDetails != null && currentEventDetails.containsKey("body")) { Map<String, Object> bodyDetails = (Map<String, Object>) currentEventDetails.get("body"); existingBody = (String) bodyDetails.get("content"); } // Preserve the meeting link (extract it from the current body if it already exists) String existingMeetingLink = null; if (existingBody != null && existingBody.contains("https://teams.microsoft.com/l/meetup-join")) { // Search for the Teams link in the existing body existingMeetingLink = existingBody.substring(existingBody.indexOf("https://teams.microsoft.com/l/meetup-join")); } // Build the new body for the update return newDescription + "\n\n" + (existingMeetingLink != null ? existingMeetingLink : "");

This was the solution I provided: extracting the link and reinserting it with the new description. Is this the correct solution?

Thank you for sharing the details of your issue. It seems like the problem lies in how the Microsoft Graph API processes updates to events with online meetings. Specifically, when updating an event, the API requires you to explicitly preserve the online meeting details (like the Teams meeting link and metadata), or it might unintentionally remove them.

Why This Happens - When updating a meeting, the isOnlineMeeting flag and other properties such as the onlineMeetingUrl and onlineMeetingProvider must be explicitly included in the update request. If these are omitted or overwritten, the virtual meeting link might be removed.

Your Solution:

Your approach of extracting the meeting link from the body and reinserting it into the updated body is a valid workaround. It ensures the Team's meeting link is preserved.

However, there are additional improvements to make the solution more robust:

Preserve Online Meeting Details - When you retrieve the existing event, make sure to extract the onlineMeetingUrl from the event's metadata. This URL is crucial for maintaining the online meeting status.

Include isOnlineMeeting: true - Always include the isOnlineMeeting: true flag in your update request. This indicates to the API that the event should remain an online meeting.

Update the Event Body - If the API still removes the onlineMeetingUrl, you can use your current approach of reinserting the meeting link into the body. This ensures that the Team's meeting link is preserved.

Handle Missing Links Gracefully - If the link is not already in the body, retrieve it from the onlineMeetingUrl field of the existing event and append it to your new description.

Here’s a refined version of your logic that incorporates these improvements:

// Extract existing meeting details String onlineMeetingUrl = (String) currentEventDetails.get("onlineMeetingUrl"); String updatedBody = newDescription + "\n\n" + (onlineMeetingUrl != null ? onlineMeetingUrl : ""); // Include all necessary properties in the update request updatedEventDetails.put("isOnlineMeeting", true); updatedEventDetails.put("onlineMeetingUrl", onlineMeetingUrl); updatedEventDetails.put("body", Map.of("contentType", "HTML", "content", updatedBody));

By following these steps, you should be able to maintain the Teams meeting link during your updates.

I hope this information helps.
