altering retention policy for deleted items in Office365

By default, Office365 mailboxes retain deleted items for 30 days.  This is a bit short, I think.  I typically like to make this limit 90 days to one year.  Here are the powershell commands needed to run to make that happen (365 days in this example):

PS C:\scripts> enable-organizationcustomization
PS C:\scripts> Set-RetentionPolicyTag "Deleted Items" -AgeLimitForRetention 365


This is based on getting into PowerShell, based on my directions here:
