cause

Reasons for the error include the following:

• Exchmem.dll does not exist in the System32 directory
• The path to the Microsoft Integration\Microsoft Exchange directory is not in the Environment PATH variable.
• The mailbox you are using for the source MAPI profile does not have the correct permissions. 

fix

To resolve the exchmem.dll issue, follow these steps:

1. Refer to the Note near the bottom of this article and determine if you want to verify the DAPI dependencies. If so, verify them now.
2. Ensure the Exchange Migrator is closed.
3. Open Windows Explorer on the Exchange Migrator console computer.
4. Browse to the Exchsrvr\bin directory.
5. Copy the file exchmem.dll.
6. Paste it into the local System32 directory

To resolve the environment PATH variable issue, add the Microsoft Integration\Microsoft Exchange directory to the environment PATH variable.

To resolve the permissions issue, verify the account you are using for migration has the correct permissions. Refer to the following NetIQ Knowledge Base article for information about the required permissions for Exchange Migrator:

note

If you would like to verify the DAPI dependencies before copying the exchmem.dll file to the System32 directory, download and install Dependency Walker from . If you have the Windows Support Tools installed, click Start > Programs > Windows Support Tools > Dependency Walker to start Dependency Walker.

To use Dependency Walker, follow these steps:

1. Click File
2. Select Open 
3. Browse to DAPI, which is usually located in two places:
   • c:\Program files\Microsoft Integration\Microsoft Exchange 2000
   • c:\WINNT\System32
4. Click Open

Any dependency displaying a yellow circle with a question mark has a problem. You may have to replace and register the corrupt file. NetIQ highly recommends researching the issue before making any changes.
