Unfortunately, under WM2003 (unlike under its successor, the WM2003SE), it's not possible to increase the Pocket Inbox text body font size.
The three registry keys under [HKEY_CURRENT_USER\Software\Microsoft\Inbox\Settings] MsgListHeaderFont, MsgListBoldFont
only set the font sizes in the mail list - and not even they can be set to any size. The practical maximum is around 100-110 instead of the deafult 80. Over this, the following cutting effects will be seen (the bold size, MsgListBoldFont, is set to 200; MsgListReadFont is set to 100):
As WM2003 (the operating system that runs on your PDA) has no way of setting global non-menu/non-dialogbox font sizes (you may want to read my post at http://www.pocketpcmag.com/forum/top...TOPIC_ID=15752
on this), there is no way to increase your fonts easily (that is, while in Pocket Inbox and not, say, copying your messages to, say, Pocket Word, and read them there).
Therefore, what I recommend is switching to WebIS Mail (http://www.pocketinformant.com/p_webismail.php
) entirely. It also has font size setting capabilities:
With that, your fonts can become really large:
