spoofed email and spam events

I have a few questions that are likely related.

First, is there a way to block spoofed emails? The ones that look like I sent myself an email but when you dig into the actual sender, its a random non-existent email and always spam?

Second, I have spam events showing in my calendar on my phone that say they are from outlook but they don't show on desktop. These spam events are often linked to those spoof emails so I can't block them.

Third, I do not have an option "delete without responding" on my phone and that is what all the forums say I need to use to prevent the spammer from knowing my email is active. Can I just use the "delete event" or will that send a notification that I responded?

Help!

Hi Brigette Bryan,

Thank you for posting your question in the Microsoft Q&A forum.

Follow these steps to remove and prevent spam events and spoofed emails in your Outlook Calendar on iPhone:

1. Remove Spam Calendar Events

Spam events often come from subscribed calendars or hidden sources on your iPhone.

Step 1: Delete Subscribed Calendars

  1. Go to Settings
  2. Tap Mail
  3. Select Accounts
  4. Choose Subscribed Calendars (if available)
  5. Delete any calendar you do not recognize.

Step 2: Check the Calendar Application

  1. Open Calendar
  2. Tap Calendars at the bottom
  3. Look for suspicious calendars or those with a .ics URL
  4. Tap Information (i) > Delete Calendar

Step 3: Remove Profiles if Spam Persists

  1. Go to Settings > VPN and Device Management
  2. If you see any unknown profile or configuration > select Remove Profile

2. About Fake “Self-Sent” Emails

These are spoofed emails, not from your account. You can:

  • Report as Junk or Phishing in Outlook to improve filtering.
  • Create a Rule in Outlook Web to block emails where “From” is your own address but invalid.

3. Safely Delete Spam Events in Outlook iOS

If you see spam events in Outlook iOS:

  • Open the event > select Delete
  • When you delete a spam event by selecting Delete, the app will not send a response to the sender
