Add Microsoft Mail Support to Outlook 2002
Source: http://www.poremsky.com/msmail_xp.htm

Outlook 2002 no longer includes support for MS Mail.

Why? Because MS Mail is not Y2K compliant. It's also very old technology and only supports

mail, not special folders such as calendars, tasks and contacts.

Old or not, it still works great as a post office, enabling small LANs to have mail service.

To enable MS Mail as service, you need to hack the mapi service file (mapisvc.inf) to

restore support. You'll also need MSFS32.dll from one of the workstations still using MS

Mail. An installer is available here that makes restoring MS Mail service easier.

To add MS Mail back to Outlook 2002 as a service (unsupported by MS, use at your own risk):

1. Add

MSFS=Microsoft Mail

to the [Services] section of
C:\Program Files\Common Files\System\Mapi\1033\mapisvc.inf


2. Add this to the end of mapisvc.inf (watch for broken lines - each line begins with PR_,

except the last 3):

[SFS_AB]

PR_SERVICE_INSTALL_ID={6485D278-C2AC-11D1-AD3E-10A0C911C9C0}
PR_RESOURCE_TYPE=MAPI_AB_PROVIDER

PR_SERVICE_ENTRY_NAME=ServiceEntry
;WIZARD_ENTRY_NAME=WizardInformation
PR_RESOURCE_FLAGS=SERVICE_SINGLE_COPY
Providers=SFS_AB, SFS_MS, SFS_XP


3. Add MSFS32.DLL to
C:\WINNT\system32\

(get it from another computer that has ms mail - it's about 515 kb.)

Thanks to MVP Dmitry Streblechenko for comparing the inf's and determining what was needed.

For the editing challenged or just plain lazy, MVP Vince Averello compiled an installer to

automate the process for you. It's here, http://www.poremsky.com/files/MSMail4XP.EXE. It

also includes the workgroup post office (wgpo) files, for creating new post offices or

administering old ones.
