Exchange Powershell "Cannot save changes made to an item to store"

When running the following powershell command you receive the "Cannot save changes made to an item to store"

[PS] C:\Windows\system32>Get-Mailbox -Server "dcexmailp02" |
Set-CalendarProcessing -ProcessExternalMeetingMessages $true
Cannot save changes made to an item to store.
+ CategoryInfo : NotSpecified: (14:Int32) [
Set-CalendarProcessing], QuotaExceededException
+ FullyQualifiedErrorId : DF365789,Microsoft.Exchange.Management.StoreTasks.
SetCalendarProcessing

In additional if you run:

[PS] C:\Program Files\Microsoft\Exchange Server\v14\Scripts>Get-Mailbox
| Set-CalendarProcessing -ProcessExternalMeetingMessages $true
Cannot save changes made to an item to store.
+ CategoryInfo : NotSpecified: (21:Int32)
[Set-CalendarProcessing], QuotaExceededException
+ FullyQualifiedErrorId : DEBD37F4,Microsoft.Exchange.Management.StoreTasks.
SetCalendarProcessing

Resolution: You have a mailbox that has a quota of 0 set. In this case, I had configured a mailbox with a 0 send\receive limit for users to use to check Freebusy times during migration coexistence and prohibited the account from sending\receiving email.
