Outlook Calendar - Updating Meeting Invite Issue & the Option to select notify added/deleted attendees is not available

Edith Badkar 1 Reputation point

I have been having inconsistent Outlook meeting invitation problems. I use app on my desktop and I am an editor on my boss's calendar:

1) When I open a recurring meeting on a calendar that I am delegate and editor and select to modify the one appointment in the series, and I add a new Attendee, and once I click on Send Update it automatically sends a meeting cancelation to the original attendee and only invites the new attendee.

2) Also, before sending the meeting update it does not give me the option to Send updates only to added or deleted attendees or Send updates to all attendees, and sends the update to everyone if I have a large group. Why does MS remove features and change without notification to users.

    I had a similar issue with a user and found the solution for her.

    After some googling I found out that this is a part of the 'Microsoft 365 Features' specifically 'Shared Calendar Improvements' which is default on OWA. On the Windows application you can turn this off by doing the following:

    1. Right click Mailbox
    2. Data File Properties...
    3. Advanced...
    4. 'Advanced' tab
    5. Untick 'Turn on shared calendar improvements'

    HI Am having this issue also and already have the 365 Features button checked. This is really a problem for EA's who need to manager their executive Calander as all attendees get updated each time a change to a meeting is made. Eg new person added or removed.
