You may experience the following symptoms on your Microsoft
Exchange 2000 Server or Microsoft Exchange Server 2003 computer:
- Messages that have attachments build up in the Simple Mail
Transfer Protocol (SMTP) local delivery queue on the destination Exchange
Server computer. These messages are encoded by using the Microsoft Outlook Rich
Text formatting or the Transport Neutral Encapsulation Format (TNEF) content
- Messages that have attachments that use the MIME body part
of the Application/MS-TNEF content type encoding are successfully delivered to
- The Exchange Server computer cannot send messages that have
attachments that are encoded using Rich Text TNEF. Messages that use the Rich
text TNEF option and that are sent to another routing group or to the Internet
are received without the attachment. The attachment icon is present, but when
you try to open the attachment, you experience one of the following behaviors:
- If you use Microsoft Outlook as a MAPI client, you
receive the following error message:
- If you use Microsoft Outlook Web Access (OWA) or a Post
Office Protocol version 3 (POP3) client, the attachment opens, but it is
- The following event ID messages are logged in the
Application log in the Event Viewer:
Engine Type: Error
Event ID: 12003
Description: Error 80070003-82000387 occurred while processing message email@example.com with subject 'test'.
Category: Exchange Store Driver
Event ID: 327
Description: The following call : EcSetFileHandleProp to the store failed. Error code : -2147024893. MDB : 5420fe97-20a4-4233-ab4d-ab05819a7959. FID : . MID : . File : C:\Program Files\Exchsrvr\Mailroot\vsi 1\Queue\NTFS_cbf2f24801c0cc77000000c6.EML.
- You may see an increase in nonpaged pool usage. This occurs because the file handles that are being allocated in IIS and are transferred to the Exchange Information Store. These file handles are kernel objects that are guaranteed to always be available in the memory. When the Exchange Information store is configured incorrectly, it cannot find the message file to set the file properties on by using file handles. Therefore, the handles are not used by the Exchange Information store and cannot be closed. These nonpaged pool allocations are represented by using an OvfL Tag and are listed with a source of EXIFS File Control Block Overflow List. In this case, the following error message may be seen in the System log:
Event Type: Error
Event Source: Application Popup
Event Category: Srv
Event ID: 2019
Computer: computer name
Description: The server was unable to allocate from the system non-paged pool because the pool was empty.
This problem may occur if you move the Exchange Server
information store database files to another folder on the Exchange Server
computer, and then delete the old folder in which those files were stored.
For example, if you install Exchange Server in the default
installation folder (C:\Program Files\Exchsrvr), the database files are stored
in the C:\Program Files\Exchsrvr\Mdbdata folder by default. If you move the
database and log files to the E:\Program Files\Exchsrvr\Mdbdata folder, and
then delete the C:\Program Files\Exchsrvr\Mdbdata folder, you may experience
the behaviors described in the "Symptoms" section.
occurs because the information about the folder in which the Exchange Server
database and log files are stored is written to the Windows registry in the
following location (where C:\Program
is the folder in which the database and
log files are stored):
Value name: Working Directory
Value type: REG_SZ
Value data: C:\Program Files\Exchsrvr\Mdbdata
The message conversion process uses the Working Directory
parameter as its temporary directory during the conversion
process. If the folder structure is missing, or if the registry entry points to
location that is not correct, the conversion process is not successful
To resolve this problem, use one of the following methods:
Method 1: Re-create the Deleted Folder Structure
Re-create the deleted folder structure as it is referenced in the
registry location that is specified in the "Cause" section.
Method 2: Edit the Registry to Point to the New Folder Structure
Edit the Windows registry to specify the new location of the
Exchange Server database and log files. To do so, follow these steps.
This section, method, or task contains steps that tell you how to
modify the registry. However, serious problems might occur if you modify the
registry incorrectly. Therefore, make sure that you follow these steps
carefully. For added protection, back up the registry before you modify it.
Then, you can restore the registry if a problem occurs. For more information
about how to back up and restore the registry, click the following article

- Locate the following registry subkey:
- In the right pane of Registry Editor, double-click
- Edit the path in the Value data box to
point to the new location of the Exchange Server database and log files, and
then click OK.
- Quit Registry Editor.
