Having spent the last day and a bit re-installing software on my Dell Inspiron 530, I was disappointed to find that the “Send To” option in Micorsoft Office 2007 was greying out “email recipient”, despite having a fully working Copy of Mozilla Thunderbird to communicate with.
I assume this is an error in the installation, rather than a protectionist measure by Micorsoft, although it may be there to encourage people to install Microsoft Outlook, or use the Microsoft mail client that is built into Vista, as a replacement for Microsoft Outlook Express.
There is a fix, but it does require a registry edit that worked for me on Micorsoft Windows Vista Premium. It will probaqbly work on other versions of windows.
You should only attempt this if you are happy editing your windows registry with Regedit and understand that there are terrible consequences if you make some errors.
- Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Messaging Subsystem
Locate the following registry values. Typically, these values are listed in the Windows Messaging Subsystem key.
Name Type Data
MAPI REG_SZ 1
CMC REG_SZ 1
CMCDLLNAME REG_SZ Mapi.dll
CMCDLLNAME32 REG_SZ Mapi32.dll
MAPIX REG_SZ 1
MAPIXVER REG_SZ 1.0.0.1
OLEMessaging REG_SZ 1
- If any of these registry values are missing, follow these steps to add the values:
- Click the Windows Messaging Subsystem subkey, point to New on the Edit menu, and then click String Value.
- Type the name of the missing value, and then press ENTER.
- Click the new value, and then click Modify on the Edit menu.
- In the Edit String dialog box, type the correct value for the missing string value in the Value data box.
- Repeat steps a - d for each value that is missing from the table that is in step 1.
- On the File menu, click Exit
Finally, when you restart your Micorsoft Office 2007 application, the “send” option on the file menu will include “Email” as a functional option and Microsoft Word or Excell will be happy to send documents as attachments using Mozilla Thunderbird, or some other Email client.
