I get a lot of event invites. Often, I can get to these emails only later. Thus, I want a way to find and mass delete all emails with invitations to events that were in the past. Is there a simple way to do this?
you can simply search with this string :
filename:ics you'll find all the invitations.
After that you can select all of them and delete them.
You can mix operators to do something more precise like :
filename:ics after:2010/8/20 before:2016/8/01
