WORKAROUND

To change the message text word-wrap, a new registry key has been created.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To correct this problem, apply the fix described in the "Resolution" section above, and then perform the following steps:

Start Registry Editor (Regedt32.exe).

Locate the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\
ParametersSystem

On the Edit menu, click Add Value, and then add the following registry value:


      Value Name: IMAP4 Line Wrap Size
      Data Type:  REG_DWORD
      Value:      Type the maximum line length in either decimal or
                  hexadecimal.

NOTE

Quit Registry Editor. Stop and restart the information store for the change to take effect.
