Is there any way to send an event invitation to multiple people, but hide invitees' email addresses from recipients? I need to keep their details private...

Hi,

I'm creating a series of events in Lightning, and sending invitations to all my adult class students. Legally, and ethically, I have to keep their personal details private. This includes their email addresses. I can't find a way to send invitations to a dozen people, without them seeing everyone's email addresses. I need something like a bcc option really. Is there a way please? Google calendar seems to be able to do it, but I don't want to use that, I far prefer TB/Lightning - largely because I can then send invitations from my business address instead of Gmail.

Thanks very much, Melanie

In the event editor in Lightning, I see a checkbox which invites me to send a separate email invitation to each attendee. It seems to do what you ask for.

The following is intended as general guidance about changing the to: designation in Thunderbird. I must admit I'm not sure how it works with calendar event invitations. I need to check. Of course, amongst colleagues and in the workplace generally, it's not required to hide addresses, and as that's pretty much the only context I have used automatically generated invitation emails, I hadn't found any need to use bcc:.

Thunderbird has bcc. Click on to: to change it.

Tip: change it when you add the first address, then each address you subsequently add will be set to bcc: automatically.

If you're using a Mailing List, bcc: will apply to each address in the list too.

And try F9 to see a Contacts Sidebar in the Compose window. This has explicit "Add to..." buttons.

Ah, turns out I needed to update my TB and Lightning, didn't have the latest version which does provide exactly what I needed. Tested it, and it works. Thanks so much Zenos for pointing me in the right direction :-)
