Exchange 2010 – Change resource reservation maximum duration

Exchange 2010 is a great tool to keep your resources organized.

You just have to create a user as a Resource or Room and set it to auto accept the requests.

The only issue is, if you do nothing else, you cannot reserve resources for more than 24 hours, which is the default value for Exchange.

So, to solve this issue there a PowerShell cmdlet to set a new value.

Here’s how:

  1. Open the Exchange 2010 Management Shell
  2. Execute the following cmdlet:
Set-CalendarProcessing -Identity “ResourceName” -MaximumDurationInMinutes Minutes

Note that 1440 is the number of minutes in 24 hours.
