TITLE   :XADM: Exmerge Archive Function Requests Too Much Disk Space
PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0,5.0,5.5
OPER/SYS:
KEYWORDS:exc4 exc5 exc55

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you run the Exmerge utility in the two-step mode and archive to the target
store, it may report that you need several gigabytes (GB) of space (sometimes
larger than the size of the Priv.edb file) even though you are filtering for a
particular attachment.

CAUSE
=====

The Exmerge utility figures the required disk space to perform the copy or
archive function based on every item in each mailbox even if you specify a
criterion of a particular message or a particular attachment.

WORKAROUND
==========

Map a drive letter to a server that has more than the required space and then
change the default c:\Exmergedata folder to that mapped drive letter. When you
scan for viruses or particular files, the required space is the size of the
attachment plus between 60 kilobytes (KB) and 100 KB at the most.

An additional way to work around this behavior is to specify a date range using
the Options button. This bypasses the addition of the size of the mailbox, and
Exmerge will display Unknown for the size, and subsequently ignore how much free
space is available.

STATUS
======

This behavior is by design; the Exmerge utility assumes that there is the
possibility of moving every message.
