Calendar invites to others - How do I get rid of the "Invitation to" on the start?

Calendar

When sending calendar invites, I have noticed that the invite received by other people starts with “Invitation to”, e.g. if I set up a calender event entitled “PWI Talk”, other will receive an event titled “Invitation to PWI Talk”.

How do I stop this?

MS Outlook does not do this. Thunderbird adds “Event Invitation:” which is just as annoying and one of the reasons I’m looking for an alternative program.

Why does eM client do this?

Hello Phil,
it is strange that these invitations are named differently, as mail invitations are always generated by the server, not the mail client.
What calendar service do you use?

Olivia
