How do I delete spam meeting invitations in Outlook without "declining"? (New Outlook)

Shoots 25

I need to delete a spam meeting invitation in Outlook. I don't want to select "delete and decline" because I don't want to send an email to a spammer. I have searched online but haven't found an answer. I finally physically disconnected from the internet. However, when I tried to "delete and decline," the spam meeting, I got the message "Couldn't delete event." The spam event then reappeared on my calendar. Especially on my smartphone this appointments are super annoying because they take up more space than my real appointments!

You can report this to Microsoft by using the Feedback facility in the new Outlook. On the Help tab, click Feedback and then click Report a problem.

I think I found one workaround for deleting a spam invitation without declining it. I did this on my iPhone. With the mobile Outlook app, it seems there's no requirement to send a decline.

Hi Shoots and Fernando

Thank you for sharing your feedback and concerns. I completely understand how frustrating this situation can be, and I truly appreciate you taking the time to explain your experience.

Currently, the available workaround is to use the Classic Outlook desktop app, where you can still delete a meeting using “Do Not Send a Response.” I understand this might feel inconvenient, and I’m sorry if this seems beyond your current setup.

If the event is clearly spam, another option is to simply delete the meeting and report the email as junk, as I mentioned earlier.

I understand this isn’t an ideal experience, and your feedback is very valuable. Thank you for being part of the community

Hi,

Thanks for answering. But this is not a solution. The problem is:

There seems no way to prevent spam invitations to automatically be added to the calendar. Why? before, there was a possibility to disable it, and to chose manually which invitations we wanted to add, which obviously was the preferred option. Why now are you forcing spammers right into our calendar? Besides, these spam events are programmed for many hours, sometimes for days, conflicting with actual legit events, and preventing the legit ones to be added.

Going back to classic Outlook isn't a solution for everybody.

You can't report it as junk as, many times, there is no email, the invitation is added to the calendar without an email.

This problem demands a real solution from Microsoft. The problem will only get bigger. It's really a violation of privacy that spammers can force their way onto your schedule without your consent. And to top it off, you can't remove it - unless you decline their "invitation" which notifies the spammers that your email is attractive for spam. Thank you for trying Gabriel-N.

Dear Shoots

Thank you for contacting the Q&A Forum!

I completely understand how overwhelming it can be when spam meeting invitations clutter your calendar, and I appreciate that you want to remove them without notifying the sender.

First, I’d like to share some insight: the new Outlook (Web and Windows) no longer includes the option to delete a meeting with “Do Not Send a Response.” This means you cannot perform this action in the new Outlook experience. This feature is only available in the Classic Outlook desktop app. If you’d like to use this option, you can switch back to the Classic Outlook desktop app by clicking “Go to Classic Outlook” in the app (if available).

Once you’re in Classic Outlook, navigate to your Calendar, right-click the event, select Delete, and then choose Do Not Send a Response.

After you’ve finished, you can switch back to the new Outlook anytime using the “Try the new Outlook” toggle in the top-right corner. User's image

If the spam event comes from a specific sender, you may also consider blocking the user or reporting the email as junk to prevent future invitations.

Currently, there is no way to switch back to the old Outlook on the web, so these actions should be done in the desktop app.

If you cannot find the option to switch back and your account is part of an organization, please contact your IT administrator for assistance.

I hope this information helps! If you have any further questions, please don’t hesitate to reach out.

But you have also eliminated the possibility to refuse spam invitations to automatically being added to the calendar. So:

You prevent us to eliminate automatic calendar events by spammers, they are forced into our calendar And:

You prevent users from easily delete such events without notifying the spammer.

I did try the fix you suggested, Gabriel-N. However, when I switched to Outlook Classic, all my appointments were gone. I looked online for ways to correct this. However, the solutions seemed beyond my capabilities. The result: I still have these spam appointments clogging my calendar. By the way, I agree with Fernando! Why would Microsoft eliminate the ability to delete an appointment without replying? I worry spammers will focus even more on this weakness in the Outlook system.

Hey cool but don't tell me how "overwhelming it can be". That makes it sound like it's my problem for getting emotional while it's clearly just something I just want a solution for. You probably just used AI to generate part of your response, but please just don't.
