We have a new Server 2008 SP2 with Exch 2007 running on it. We tried to install BES 5.0 on it. Some one had installed Outlook 2007 on it first. After removing Outlook, it leaves the mapi32.dll on with version 1.0.2536.0.
I downloaded a mapi - cdo file and installed it after removing outlook but the mapi version did not change. I tried to rename and delete the mapi file even in safe mode as the admin but was not able. How can I get rid of the file or at least upgrade it to a version that will make my BES run.
cdo.dll, Version: 6.5.8131.0
BlackBerry Mailbox Agent 1 for Server BAERSMAIL - Version 5.0.0.110
mmc.exe, Version: 6.0.6002.18005
MAPI Encoding is 1
BlackBerry Messaging Agent BAERSMAIL Agent 1 failed to start. Error code 5305

You installed BES 5.0 on the mail server?

Yes on the mail server.

The BlackBerry Enterprise Server and BlackBerry Enterprise Server components do
not support installation on the same computer as the messaging server.

I am aware of that but I was told and read the post where it does work on the exchange server and I worked with people from RIM on the issue. It is not a permissions issue. It is that someone installed Outlook on the Exch box and when it came off it left the old version of the Mapi file and I can not rename, delete or replace it.

Hi,

In order to change a system file in Server 2008/Vista/Longhorn OSes, you have to take ownership of the file first. Then, change the permissions to allow your user account to change/delete the file. You can then delete it and replace it.

By default, only trusted installer is the account that can change the file and has ownership.

How would i know who the owner is? I tried the administrator both locally and from the network. Neither worked. Nor did safe mode.

i only have 2 servers, the DNS and the exchange. RIM actually tried to install it with me over a 3 day period on the exchange server. They were aware of the situation and suggest in the future I transition off the exchange server to its own server....when the economy improves I replied and they agreed....

Dont know, if this helps, because I have not tried it out on 2008.

If the problem is, that you really cant delete the file,
unregister mapi32.dll
Start your machine from a Boot CD, delete the wrong mapi32.dll
Search on the Disk for any other occurence of mapi32.dll including compressed versions like mapi32.dl_
make a folder with the same name "mapi32.dll" in the same location.
restart the machine.
remove all mapi32.dll references from the registry
reboot, delete the mapi32.dll folder
try to install the correct mapi and cdo versions.

I use this method to stop viruses on infected PCs. Even windows file protection is AFAIK unable to replace a folder with a file.
This method is rather brute force then nice, and, if not properly done, you might damage your OS.
You should make at least a backup of the system state before trying this.

Every file in an NTFS file system has an owner. Right click on the file > go to properties > security > advanced > owner tab
