Adding attachment to Meeting Invites You Do Not Own

Yes, please Microsoft, put this Outlook feature back. I am also a PA to two directors and together with other PAs in our organisation, we find it extremely frustrating not to be able to add our own files or notes to meeting invitations sent to us by 3rd parties.

Hello!

OMG, thank you! I tried those directions in the link above initially a few months back, and it did work at the time. However, a few weeks ago the "Edit Meeting" option got removed from my Ribbon, and the "Edit Meeting" button was not an option to even add back to my Ribbon.

But now it's back as an option! I don't know what little Microsoft - or my own company's IT minions - are going to make the feature available, then not available, and now available again, but thank you for prompting me to look again. I never would have realized the featured had returned. Thank you!

(I also am not using the "new Outlook" yet for the same reason, it doesn't appear to have the functionality I need to do everything I need to do yet...)

I was looking for a solution to this myself today. Going down the rabbit hole starting here, I came across this link that someone else posted... I don't even remember how I got there, but here's your workaround. It's so easy and you don't have to download 3rd party software or go reverting to an old version of Outlook or changing registry keys. You literally just add the button to your ribbon and/or quick access toolbar.

The only downside is that if the original meeting organizer sends an update and you accept it (I'm assuming you have to accept it for this to happen) then you'll lose any edits you made yourself. So just keep that in mind!

I work for a state university and our IT department forces new versions and updates on us, so I can confirm this works at least with what I have: Outlook for Microsoft 365 MSO (Version 2402 Build 16.0.17328.20550) 64-bit.

Note: I am NOT using the "new Outlook" because when I tried it I lost other functionality that I required (adding a shared mailbox as a separate account vs it being added within my account as if it was just another folder - this prevents adding any of those folders as favorites, which I MUST be able to do).

Haha such a good response! I hear ya! It has made my work life so difficult. I just cannot believe they made this change.
