Exchange 2010: Supposed Misbehavior of Outlook 2010 when proposing “New Time” in meeting requests

Created by Ingo G. from Germany:

The other day some colleagues complained about a misbehaviour of Outlook. It was reported if someone propose a new time for a meeting request, the meeting organizer is not able to accept the proposal. It looks like this:


This looked quite interesting. It took me a while to find the root cause for this:

As this feature is completely handled by Outlook, first I thought the default configuration of Outlook was causing the issue. So I had a look:



But it was set like you can see here in screenshot. As I couldn’t reproduce this behavior, I decided to have a closer look what’s going on. So I stand behind the users to see each step:

• the organizer sent a normal meeting request

• the attendee proposed the new time as follows:

He opened the meeting request and clicked on “Propose New Time”


When you do so, you will get a menu and can choose. Of course it was choosen “Decline and Propose New Time”

Note: When you choose “Decline and Propose New Time” Outlook will first decline the meeting request and then create a new one, which will be send back to the organizer. This is by design!

  1. When you tentatively accept and propose new time, the organizer still can not accept the new proposed time. The button is still grayed out. Has anyone found a fix for this?
