症状

启动 Outlook Express 时，“收件箱”文件夹的内容可能会丢失。其内容可能被替换成新的、第一次运行 Outlook Express 时出现的“欢迎使用 Microsoft Outlook Express ”邮件。您没有收到电子邮件已删除的警告，并且丢失的电子邮件也不会出现在“已删除邮件”文件夹中。

原因

如果使用 McAfee VirusScan 防病毒程序电子邮件扫描功能，则可能会发生此问题。如果安装了 McAfee VirusScan 防病毒程序， VirusScan 程序的电子邮件扫描功能可能导致“收件箱”数据库文件被损坏。使用电子邮件扫描功能时，可能发生数据库损坏。

Inbox.dbx 文件是用于“收件箱”文件夹的 Outlook Express 数据库文件。如果发生此损坏，下一次启动 Outlook Express 时，将检查 Inbox.dbx 数据库文件的一致性，删除 VirusScan 程序损坏的数据，并会生成新的、第一次运行 Outlook Express 时显示的“欢迎使用 Microsoft Outlook Express ”邮件。

USING DBXtract

IMPORTANT: While the program only reads the dbx files, it is important that OE is closed when the program is in use. This is especially true if one has background compaction turned on under Tools | Options | Maintenance. If OE is open and is accessing the dbx file at the same time as the program is, it is possible the file could become corrupted (or the entire message store could be). It is very important then to make sure OE is closed. The program itself does not modify any dbx files or any files associated with OE.

DBX files can get rather large and the larger the file the more slowly it will run. It is best to compact the dbx files in OE using File | Folder | Compact to minimize their size, but it is not necessary to compact them in order for the program to function accurately. With uncompacted folders, however, more messages or some partial messages may be extracted than the number that OE indicates are in the folder. DBXtract is designed as a recovery tool, so expect many false positives in the extraction process. Most of these will have a filename of 'No Subject'.

Recover Mode

The purpose of this mode is to recover messages that have been deleted from the deleted items folder. With the DBX files, Microsoft chops each message into 512 byte pieces. When a message is deleted from the deleted items folder (that has not yet been compacted), then OE removes the first 4 bytes of each piece, so it is not possible to recover a message in its entirety. However, with this version of DBXtract, one can recover from the deleted items.dbx file, such pieces that are still there and reassemble what is left of the pieces. To accomplish this, check the Recover Mode box. Then browse to the deleted items.dbx file and set the output directory. Then click the Extract button. A set of text files will then be extracted into the output directory. For the sake of completeness, all fragments will be recovered. A lot will have the filename NoSubject appended by a number. Most of these will be redundant and can be deleted (Make sure the by Subject check box is checked when using the Recover Mode feature, so one can distinguish between them). Images and other attachments will be incomplete and likely irrecoverable, but text and message headers should be largely intact.

The author makes no guarantees as to this software and the user, upon downloading and executing it, does so at his own risk. DBXtract has been rather extensively tested, however, and any risk would appear to be minimal (except as stated above with respect to OE being open simultaneously).
