Exchange 2013 OWA Mailbox policy issue cause of OWA error?

Within Exchange 2013 you can have OWA (Outlook Web App) Mailbox policies, in which an Exchange Admin can determine which features within OWA are available to users.

Not all organizations need to have every user to be mailbox-enabled, sometimes a mail-user (also referred to as mail-enabled user) with a forwarding SMTP address to an external mailbox is enough. However, it is surely possible that the requirements over time change and the mail-enabled user does need to be mailbox-enabled, making use of the calendar or perhaps even more efficient use of Lync integration. However, converting a mail-user isn’t just changing the RecipientType of the account. First the users

Recently the backend of my Office 365 P1 account was upgraded to the Wave 15 series of products, which obviously includes Exchange 2013.
