I have added an OMS account and sent a test message from the Accounts

How did you add this "OMS account" and what service does it reference? Can
you post the account settings?

I can see the account under the options if I go to create a new email
account but if I try typing in a mobile number it just refuses to do
anything.

Anyone have any ideas? I have searched MS help and Google without any
luck.

An associated but possibly unrelated issue is that I cannot see a
Mobile address book, even though it is showing up if I go into "Tools/
Options/Data Files/Address books"

Outlook doesn't really have any "address books". Address books are services
that reference things like Contacts folders or LDAP servers and convert the
data in the reference to a form Outlook can use. Perhaps if you tell is how
you added and configured the "Mobile address book", we can help. Is there
some phone app you've installed?
