Channel Calendar spams emails to entire team. How to disable?

Good afternoon. I am looking for some assistance with a very strange problem.

For starters, I am only on the client side so I do not have access to any admin portals or any type of elevated permissions. With this being said I know I have little to work with being only on the client side of things.

Issue:

Created a simple Channel Calendar in a preexisting teams. Every meeting invite, modification and/or deletion spams the entire group with emails. We want to use this group to track Leave but I also don't want to spam the entire team with Leave meeting emails.

I have done the following to attempt to resolve the issue myself:

I unsubscribed from the group but I am still getting emails for all channel calendar meetings invites. I added a required attendee, to the To field on the meeting creation page in teams and it still sends the invite to the entire group. I have review all of the client side team and channel settings and there are no options to repress these emails.

We know of the following solutions but the admin team is not willing to implement them:

Transport rule in EXO and or a local outlook rule to have it deleted, moved or dropped. Adding the website app to the team and make a SP calendar.

Conculsion: I cannot be the only one having this problem as I found several posts similar to mine with NO real answer or solution. I understand the backend of Teams membership is a 365 group and its going to email that specific group. Is there an option to remove the group from the To: Field? No! Is there a toggle box to select non teams meetings? No! Is there an option to not email the entire group? No! Is there an option to silently add the meeting to the channel calendar? No!

There is super limited options in this teams channel calendar. There has got to be a better way to track leave in Teams using this extremely limited calendar app. Please help!

    Hi @Ryan Lloyd, 

    Welcome to the Microsoft Q&A forum.

    Thank you for the detailed description and for everything you’ve already tried. I understand how disruptive it is when every Channel Calendar change generates email to the whole team, especially when you want to use the calendar to track leave quietly. 

    The Channel Calendar is linked to the Microsoft 365 Group behind your team. When you create or update an event in the channel, it is treated as a channel meeting, which by design sends notifications to all team members. 

    If “Send personal invites” is turned on when creating the event, Teams will email all members even if you do not add them in the “To” field. Also, some members may still receive emails because they are subscribed to group messages in Outlook. Even if admins disable group email copies, individuals may need to unsubscribe manually in Outlook or Outlook on the web. 

    To assist you further, please consider trying the following (no admin rights required): 

    1/ Track leave without emails using Microsoft Lists 

    • In the Team, add a Lists tab. 
    • Create columns (e.g., Name, Leave type, Start date, End date). 
    • Switch the view to Calendar so everyone can see leave on a shared calendar inside Teams with no inbox blasts. 

    2/ Use Shifts for time‑off requests and approvals (targeted notifications) 

    • Open Shifts in Teams, enable Time off, and share the schedule. 
    • Employees submit requests; managers approve in Teams. Only the relevant people receive notifications.  

    3/ Engage your IT administrator to proceed with the following actions: 

    • Review group subscription defaults so newly added members do not receive event copies in their inbox, and help existing members unsubscribe if needed.  
    • Consider alternative calendars (e.g., SharePoint calendars) or policies to reduce Channel Calendar posts and email traffic 

    Additionally. I strongly recommend submitting your suggestion through the Microsoft Teams · Community, where the Microsoft product team actively reviews user input. Many improvements have been made based on community suggestions, and your idea could help prioritize this feature for future updates. 

    You have clearly identified a real-world challenge, and your suggestion reflects a deep understanding of user needs. Feedback like yours plays an important role in shaping the future of Microsoft products. Once you submit your feedback, please feel free to share the link here. I would be happy to upvote it to help increase its visibility.
