This is how you can allow a conflict on bookings (booking in a calendar at the same time)for a 'room' in outlook by editing through Powershell!

Step 1: Open Powershell as an administrator and connect to exchange

You need to open up Powershell with administrator privileges and connect to o365 exchange. The link on how to do this is below: https://community.spiceworks.com/how_to/161192-how-to-connect-to-exchange-through-powershell

Step 2: Identify properties of mailbox

You need to identify the properties of the mailbox as it stands. Type in:

Get-CalendarProcessing –Identity name of mailbox | fl

This will bring up a list of results. The key result you're looking for is 'AllowConflicts' on the left hand side of the window. Make sure that the row next to it states 'False'. If it states 'True' then there is no issue and you will not need to do this.

Step 3: Change conflict state

To turn conflicts on, simply type in the command of:

Set-CalendarProcessing name of mailbox –AllowConflicts $True

This will allow calendar entries to be made side by side.

Step 4: To turn off

To turn off the conflict state, type in the following:

Set-CalendarProcessing name of mailbox –AllowConflicts $False

This should turn off the conflict state
