Adding a room reservation to someone else's meeting

_{Thursday, March 30, 2017 12:15 PM | 1 vote}

I posted this question previously at the answers.microsoft.com site and was directed here for an answer.

I work for a global company and routinely get meeting invitations from other's across the world.  I want to know is there a way for a meeting attendee (not the organizer) to add a room reservation?

As an example, half of a team is located in one office in Canada and the other half here in the USA.  Someone in Canada sends out a meeting invitation with a call-in number and a room reservation for the Canadian office.  Right now, we send out a duplicate invitation for the half of the team located in the USA just to book a room here.  Is there a way to add a second room to someone else's invitation?

Hi Steven,

To my knowledge, the attendee will need to have delegate permission to organizer's calendar to be able to change a meeting. Otherwise, it's not possible.

Steve Fan

I Found this today (about a year later)  But you can Forward the meeting invite to the room just like you would as if it was an uninvited person from your office.  Then you have the Room booked in the same meeting as your other team. This will also notify the meeting organizer what room you are in.

It would be a great improvement if also meeting location would be updated for all participants after forwarding to a meeting room and accept from the meeting room.

Luke, I would like to know how you did this?

When i forward a meeting invite, created by someone else, to the meeting room, it doesnt get auto processed - I actualy have to open the meeting room shared mailbox and accept the forward meeting request for it to ad it to the shared calendar.

Is there something i'm missing?

Any help is great.

Thanks!

+1. I am having the same issue (the meeting is not auto-approved). I've tested with both internal and external meeting organizers and experience the same result.

You wrote "I actualy have to open the meeting room shared mailbox and accept the forward meeting "

Email admin should be able to configure auto accept meetings on forward event. Auto accepting works for me in Outlook 2013, that said even though the room is booked automatically you still don't get email confirmation on that.

Good luck and thanks for sharing experience.

Through the powershell commadlet the ProcessExternalMettingMessages needs to be set to TRUE.  Here's an example: 

set-calendarprocessing -identity "ConferenceRoom" -ProcessExternalMeetingMessages $true

Good Luck!
