I am running OS X 10.10.3 and I installed 14.5.0 update which resulted in me not being able to see the Main Window (as in common with other people). I saw a fix that used Terminal to delete the preferences which worked. But when I went to the menu Outlook > Preferences > Fonts nothing happens. I can click on all the other icons and open their associated preferences, but if I click the Font icon nothing happens. Also when I compose a new message the font list is very small (just standard fonts like Calibri, Arial, Helvetica, Verdana - all other fonts are not shown in the list).

I then read about the 14.5.1 update and I installed that manually (the update did not show when I ran the Microsoft updater). Same situation. 

I have tried:

Trashing the preferences (first com.microsoft.Outlook.plist and then everything com.microsoft.outlook.XXX.plist).

Creating a new identity.

Repairing permissions.

Recovering old preference files from Time Machine backup.

Rebuilding Outlook database.

Clearing font caches with my font management program.

Nothing cures the non functioning Fonts preference pane.

Anybody got any ideas?

Thank you.
