How do you not have calendar tentatively accept a meeting? We have a calendar that has 3 delegates who must approve it. The issue is once I put a meeting request in (I am not a delegate), it shows up as "tentative" on the calendar. I don't want that to happen. I know you can uncheck "Automatically process meeting requests and responses to meeting requests and polls" in Outlook Options, but since we have many employees at our company we would have to do it for each individual user which we are trying to avoid. 

So my question is how 1) how do we disable this tentative acceptance 2) if there is no way, is there another way to create a calendar in EAC and share it with the rest of the company, have delegate approval and not have the tentative acceptance. Right now I have a room created in EAC under Recipients -> Resources. If there is another better way to create a shared calendar, please let me know. 

This is my first post on this forum so excuse me for any ignorance, just trying to get this resolved. Thank you

So, Outlook doesn't "accept" the automatically as tentative.  The appointment shows on the user's calendar only.  If other users are looking at the free/busy information on that calendar, it is still shown as free time until one of the delegates actually accepts the meeting.  I was looking in our GPO and didn't really see a way to control that setting across the organization in Outlook.  I'd test it first though, because again, if you send a meeting request to anyone, the only person seeing it as "tentative" is the recipient, not anyone else, until they accept the meeting. 

Try this:

Set-CalendarProcessing mailbox -TentativePendingApproval $false

Try this:

Set-CalendarProcessing mailbox -TentativePendingApproval $false

Hi,

If you want to disable putting new calendar items tentatively on the calendar for all Exchange users, please try to run the following command in EMS (Exchange Management Shell):

Get-Mailbox -RecipientType UserMailbox | Set-CalendarProcessing -AutomateProcessing AutoUpdate -AddNewRequestsTentatively $False

The AddNewRequestsTentatively parameter specifies whether to have the Calendar Attendant put new calendar items tentatively on the calendar. If the AddNewRequestsTentatively parameter is set to $false, only existing calendar items are updated by the Calendar Attendant.

I just tried this, I sent a meeting request for delegate approval. I asked someone else who is not a delegate to check the calendar to see if they can see the tentative acceptance and he did confirm he can see the meeting request on the calendar.

Try this:

Set-CalendarProcessing mailbox -TentativePendingApproval $false

I did set this to false, still shows up as Tentative on the calendar.

When I try this I get a message that says

"AutomateProcessing can only be enabled on resource mailboxes.
    + CategoryInfo          : InvalidData: (USER:ADObjectId) [Set-Cal
   endarProcessing], ResourceOnlyException"

We set up all the users in "Mailboxes" not under "Resource Mailboxes" which might be the reason? Again, sorry for the ignorance, our IT department here is small and we are still learning as we go.
