Ability to update or create an event without sending a notification email to attendees

Each time a new event is created or updated in Microsoft Graph API, a notification email is sent to the attendees.


We use Microsoft Graph to sync calendar event between our software and Outlook calendar. We'd like to be able to create or update an event with Microsoft Graph without having an email sent to attendees, for example when we sync past events, or when the attendees are notified by other means.


There should be an option to create or update an event without sending email.

Any news on that topic?

This is a huge issue for my organization. Are there any timelines for when this will be resolved?

+1 to this. We update event descriptions with URLs to meeting notes when they become available, but this isn't a change that anyone needs to be notified about. This causes confusion and annoys people because of the unnecessary emails. Would love to be able to specify when emails should go out like we can with other calendar providers.

This would be highly appreciated feature! Updating the description of an event or adding participants to a bigger event creates a huge amount of unnecessary email notifications. Users are annoyed even though we are transferring those notifications directly to deleted items-box.


We are using a separate sync account: If this would decrease also the amount of messages travelling through this account, we wouldn't have so many troubles with exceeding the 10.000 messages per day limit.


Hope this feature would come soon!

Representing a edtech company which synchronizes School data from a collection of MIS systems. We fetch data from MIS systems and synchronize the data to Azure/O365 environments via GraphAPI. It's critical that the students + teachers not are getting SPAMMED in their inboxes with email notifications when it comes to their lessons (Their Outlook calendar). 


Currently we are not able to offer calendar synchronization (from MIS -> Outlook calendar) due to the system SPAMMING all the users with email notifications of their calendar events created and maintained by us. 


PLEASE prioritize this feature request, we really need the option to set a flag which deactivates everything related to email notifications of calendars that we create and maintain through the GraphAPI.

Not having this feature hurts customers who are migrating to Microsoft 365 and bringing calendar data with them. In EWS, these meetings can be imported without sending new invitations, which is what most people want to avoid an invite storm during the migration. This is not currently possible in Graph and is a major problem for migrations.

Please consider adding this feature

Hi, we also need that feature if you can make it happen

Yes, this is a feature we also need. 
Having the ability to switch off the notifications is very important to us when importing calendars.
Definitely don't want to spam our users.

Google allows us to switch off the notifications, so we can provide this to users.
But I don't feel comfortable integrating Microsoft until this is added. 

Please add this feature, or let us know if we can help👍🏻
