Change the program used to open email links

hey gingerbread man,

i already tried that but it does not solve the problem at hand. it sure opens the desired email client and the application has the focus but it does not open a new email message window with the email address of the mailto link in the TO field. what kind of kills the purpose of the mailto link. is there a way to set command line options / arguments? if i could run "zdclient.exe -url "mailto:<email@address>"" it would work.

in the registry under HKCU/Software/Clients/Mail (HKLM/Software/Clients/Mail) is an entry that sets the default email client but firefox is not honoring this setting. zimbra desktop even comes along with a MAPI dll, but i have no clue how to use that in firefox.

any other suggestions?

If the application is properly registered, Firefox should recognize it. What happens when you do the following?

1. Click the Windows logo orb on the taskbar to bring up the Start Menu.
2. In the search box, type the following then press Enter: mailto:user@example.com

There are whole bunch of places in the registry where things could be messed up. For starters, check the following:

1. HKEY_CLASSES_ROOT\mailto\shell\open\command
2. HKEY_CURRENT_USER\Software\Classes\mailto\shell\open\command
3. HKEY_USERS\<random string of numbers>\Software\Classes\mailto\shell\open\command
4. HKEY_USERS\<random string of numbers>_CLASSES\mailto\shell\open\command
5. HKEY_USERS\<random string of numbers>\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\mailto
6. HKEY_USERS\<random string of numbers>\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\MAILTO\UserChoice

• The random string of numbers is specific to your Windows account. If you can't locate the exact key manually, you can use Process Monitor to find out which keys Firefox is querying.

hey again,

thanks for your reply. with Process Monitor i was able to debug the problem and figure out a solution.

Zimbra Desktop does not set the registry key HKCU/Software/Microsoft/Windows/Shell/Associations/UrlAssociations/mailto/UserChoice but firefox does read that key.

so to sum up what i did, here a list:

• delete mimeTypes.rdf as described here
• either delete HKCU/Software/Microsoft/Windows/Shell/Associations/UrlAssociations/mailto and all its subkeys or change HKCU/Software/Microsoft/Windows/Shell/Associations/UrlAssociations/mailto/UserChoice/Progid to "ZimbraDesktop.Url.mailto"
• within ZimbraDesktop set ZimbraDesktop as default mail client
