Another week, another custom form bug. This time it's the font used in the first field on a custom form: it's tiny. The field properties look fine, with the font size is set to a reasonable size, but the text is very small and unreadable.
This is fixed in the April 8 2014 updates for Office 2013.
I've only seen it forms created in older versions of Outlook and opened in Outlook 2013, but not every form created in older versions of Outlook is affected.
This comment from a user describes the problem perfectly:
I created a custom Contacts form some time ago. It worked fine until recently. Now the first field in the form displays in a very tiny font. I checked the properties of the field, and the font and font size are correct and furthermore are the same font and font size as in all the other fields in the form, which display correctly. I tried resetting the font and font size a number of ways, but the field still displays in a very small size.
Microsoft is looikng into the problem, however, Dave from SalesOutlook.com offers this solution, while we wait for an official fix:
Microsoft released an update to RICHED20.DLL which is a Microsoft Word component that caused this issue.
Back-level the file RICHED20.DLL to: (You can obtain it from any PC that is working.)
RICHED20.DLL is in the Microsoft Shared folder. In the Click to Run installs that most Office 2013 users have, RICHED20.DLL is located at
C:\Program Files\Microsoft Office 15\root\vfs\ProgramFilesCommonX86\Microsoft Shared\OFFICE15
Volume licensed MSI installations will have RICHED20.DLL at
C:\Program Files\Common Files\microsoft shared\OFFICE15
Rename RICHED20.DLL to RICHED20.DLL-15 (Approve the dialogs that come up) and copy an earlier version of the RICHED20.DLL to the folder. You'll need to restart Outlook for the fix to take effect.
To reverse the fix, delete or rename the copied RICHED20.DLL and remove -15 from the original RICHED20.DLL filename.
