Exchange Set Equipment Mailbox Reservation Duration In Bulk

In my current environment, we migrated from Lotus Notes to Exchange 2016, and some users don't like the changes that come along with it, especially when dealing with booking Resource Mailboxes.

The default maximum duration to reserve an Equipment Mailbox is 24 hours in Exchange. It makes sense for meeting rooms, but most users will need resources such as cars for longer than a day, which results in them having to book several appointments on the Equipment Mailboxes.

We're going to change the max duration to 7 days (to give users a little more leeway) and we're going to change it for all Equipment Mailboxes at once.

This is really easy with PowerShell!

Fire up the Exchange Management Shell (EMS) and run the following cmdlet:

Get-Mailbox | where {$_.recipienttypedetails -eq "equipment"} | Set-CalendarProcessing -MaximumDurationInMinutes 10080

**Notes**

- I set the value to 10080 which is 7 days.

- The default value is 1440 minutes (1 day).

- The maximum value you can enter is 2147483647 (which is 40 centuries, in case you're wondering).

- You can set a value of "0" which is unlimited - prolly don't wanna do that since other users couldn't then book the resource, unless you've allowed overlapping bookings.

- For recurring meetings, the value applies to the length of an individual meeting instance.

Now your users can schedule those long road trips reserve a projector for a conference in one shot!
