SYMPTOMS
When you create a MAPI program or a Collaboration Data Objects (CDO) program to perform operations on messages from a Microsoft Exchange Server 5.5 information store, the program may return a MAPI_E_NOT_ENOUGH_MEMORY error when the program tries to access a particular message. The MAPI_E_NOT_ENOUGH_MEMORY error is also expressed by using the E_OUTOFMEMORY code and by using the hexadecimal error code 8007000E. Additionally, the program user may receive an error message that is similar to the following:

There is not enough memory available to perform the operation.

[Microsoft Exchange Server Information Store - [E_OUTOFMEMORY(8007000E)]]



CAUSE
This problem occurs because the Microsoft Exchange Information Store may return a remote procedure call (RPC) response to the client RPC request. The RPC response indicates that the buffer size that is required for the RPC data is larger than the maximum buffer size of 32 kilobytes (KB). The client handles this request to set up a buffer size that is too large as a memory error.

WORKAROUND
To work around this problem, open the message by using another method, change the message size, and then save it. For example, open the message by using Microsoft Outlook Web Access. Because this problem only occurs with messages of a certain size, the MAPI program or the CDO program can access the message successfully after you change the message size.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section of this article.
