357966 - (MapiCompatIssue) Third-party program finds Thunderbird-supplied Mapi32.dll incomplete/incompatible

Status: RESOLVED DUPLICATE of bug 109362

(Thunderbird :: Build Config, defect)

Description

[Svend Garnaes]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7

When Thunderbird is chosen as the preferred mail client, it replaces the
existing c:\windows\system\mapi32.dll with its own supplied version.

This causes a third-party application to report: 
   Error starting program.
   The OUTLLIB.DLL file is linked to missing export MAPI32.DLL:36

Reverting the mapi32.dll file to the original (which Thunderbird gracefully
backs up) solves the problem for the third-party application, but then
Thunderbird is no longer the preferred mail client, and the prompt to select
that reappears when Thunderbird is started.

Original Mapi32.dll:       716,048 bytes  06 Aug 97
Thunderbird's Mapi32.dll:    6,265 bytes  18 Sep 06

It would seem the third-party application relies on some functionality
present in the original Mapi32.dll, but absent in Thunderbird's Mapi32.dll.


Reproducible: Always

Steps to Reproduce:
1. Install Thunderbird
2. Select as preferred mail client
3. Start third-party application

Actual Results:  
Third-party application reports an error in starting program:
The OUTLLIB.DLL file is linked to missing MAPI32.DLL:36

Expected Results:  
Third-party application should have been unaffected by the switch of mail
client (from Eudora to Thunderbird, as it happens)

Original Mapi32.dll is reported by explorer as:
