- Report the spam invitations as phishing or junk to Microsoft. You can do this by selecting the invitation in your inbox and clicking on the "Report" button at the top. This will help Microsoft improve their spam filters and protect other users
Feature Request 1:
It would be helpful if this were an option on the calendar event itself - I see this junk pop up on my calendar, and I can only Decline the invite (which has the effect of confirming my address exists for the spammer, so they can send more spam), or Delete it - there is no option to report it as junk.
Feature Request 2:
In Gmail, it is possible to configure the event settings to only add invitations to my calendar if the sender is known/safe. This would be a useful setting for those of us who don't want to block all unknown email senders, but do wish to block unknown senders from littering our calendars with spam.
Feature Request 3/Bug:
If I open a spam calendar invite from my calendar, it does not seem to respect my Junk E-Mail setting to only load images/links/attachments from safe/known senders, so the image loads - which also has the effect of confirming to the spammer that my email address is real.
This is happening with such frequency it's making the service unusable.
