I would like to change the default font size for Outlook.

I can change it for every folder (in View/Current View/Customise
Current View/Other settings) one at a time but this is proving
longwinded as there are lots of folders.

Clear all custom views with the /cleanviews command line switch (click
StartRun, enter "outlook.exe /cleanviews" - without the quotes, but with
the space), then modify the Messages view (ViewArrange ByCurrent
ViewDefine Views. Select Messages, click Modify) to use the fonts you
want. All mail folders which use the Messages view by default will then
exhibit the changes you made. Sent Items, however, doesn't use the Messages
view, it uses the Sent To view. You can change that one (and any of ther
other built-in views) at the same time you change Messages, if you wish.
