Sorting properties from get-mailbox on a single mailbox, how?

Question

get-aduser username -Properties *  gives a nicely sorted list of the properties for a user's AD account. 
get-mailbox username | fl * gives a nicely
unsorted list of the properties for a user's Exchange mailbox.
Anything more elegant for sorting the get-mailbox output?
Get-Mailbox username | fl * | Out-File -FilePath c:\username-mailbox.txt
Get-Content C:\username-mailbox.txt | sort
What is the technical terminology for the type of output produced by get-mailbox username?
Thank you for your time, Joe

Hear ya Bill.  But I'm only returning a single PSObject (Microsoft.Exchange.Data.Directory.Management.MailEnabledOrgPerson), and I'm attempting to sort the properties on the single object.  Sorry I'm not explaining this well.
Example Output from: get-mailbox
Name                   Alias                ServerName      
ProhibitSendQuota
kcarael               kcarael               svrwmail     unlimited
cuqt3                  cuqt3                  svrwmail     unlimited
lsren                  lsren                  exchange03   unlimited
roreerb                roreerb                      exchange03   unlimited
pacffsdfs              pacffsdfs                       exchange03  
unlimited
beon                  beon                  exchange03   unlimited
Not a problem to sort:  get-mailbox | sort alias
Output from: get-mailbox someuser
Name                   Alias                ServerName      
ProhibitSendQuota
someuser              someuser              mbxn04    12.6 GB (13,529,147,392 bytes) 
Example Output from: get-mailbox someuser | fl * (or get-mailbox someuser | Select-Object *)
RoleAssignmentPolicy                   : Default Role Assignment Policy
SharingPolicy                          : Default Sharing Policy

IsMachineToPersonTextMessagingEnabled  : True

I'm not sure what to sort on...  I've tried just: get-mailbox someuser | Select-Object * | sort
The output looks the same as output from: get-aduser someuser 
This doesn't work either: get-aduser someuser | sort -descending
Thank you, Joe
