Meeting Room & Calendar - Exchange 2016


I have couple of questions regarding Meeting Room of Exchange 2016 as below:

1- How to prevent double booking for certain room?
2- How to receive a confirmation of my booking?
3- When I go to outlook >> calendar >> Open Calendar >> From Room List then, it takes long time to show the result and it shows all reservation as Tentative?

Thank you

The Tenative part is another party possibly might have to approve the booking.  This I know from my previous job as I was the AV Tech as well.  Do all rooms show up as Tentative.  Has this ever happened before and what has changed since the last time it worked?  I could help you just need more history.

Next.  Is each room setup as a mailbox?  This needs to be in place. To enable a pop up that the room is booked please try this, you have to enable the resource account log in, start outlook and connect to Exchange as the resource.  Go to tools, options, Calendar options. resource scheduling and check the first 2 options. (Automatically accept meeting requests and process cancellations and Automatically decline conflicting meeting requests.

Disable the resource account again.

The popup will show up under the following condition.

Create the meeting and book with outlook.

for 1 and 2  have a read of the below but the easiest way to achieve this is to set the automatic processing to autoaccept and the allow conflicts to False

 run this command against your mailbox in exchange shell to check what the settings are

Get-CalendarProcessing rommname | fl

line 2 and 3

you want it to be as below

AutomateProcessing                  : AutoAccept
AllowConflicts                      : False

to change it use Set-CalendarProcessing -Identity "mailbox" -AutomateProcessing AutoAccept -AllowConflicts $false
