Outlook launches without a Home Screen.

Menu Items are accessible and function properly (i.e. compose and send email, access Accounts etc.).

However, Home Screen does not render and you cannot see (or access) Mailboxes, Calendar, Contacts etc.

Appreciate that this is an issue with Public Beta Version but Apple has now issued this to One Million Mac Users and plenty of Microsoft Users rely on Outlook for Mac so, will need to be resolved.
