Every day a new challenge.
A customer requested to set the default message type in OWA to Arial.
Like almost ever you can do this easy with PowerShell:
Get-Mailbox -RecipientType ‘UserMailbox’ | Get-MailboxMessageConfiguration | Set-MailboxMessageConfiguration -DefaultFontName Arial
You can also do this for various parameters. Take a look at TechNet for a full list of parameters.
