I want to find all invitations that I received to my IMAP mailbox / email account.
But the “Invitations” view in the right sidebar seems to only work for email accounts with an included calendar like Microsoft Exchange.
It does not show the invitations that I received to my IMAP mailbox / email account.
I tried creating a search folder searching for attachments named *.ics which works partly but it looks like not every invitation has such an attachment.
Probably depending on the program it was sent from.
So how can I search for really all invitations?
