    • The 'Show Inline Attachments' option is now turned on by default (In previous versions it was turned off).

Using OutlookAttachView

OutlookAttachView doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - OutlookAttachView.exe
If you have only one profile in your Outlook, and this profile doesn't require any password, you can run OutlookAttachView even without starting Outlook, and it'll automatically scan the mailbox of your current Outlook profile. Otherwise, it's recommended to open Outlook in the right profile before starting OutlookAttachView.
After running OutlookAttachView, the 'MailBox Scan Options' window will be displayed. This window allows to choose to scan your mailbox only in specific dates range. After choosing 'Ok' in the options window, OutlookAttachView starts to scan your Outlook messages and display the found attachments in the main window of OutlookAttachView. If you want to stop the scan process, simply choose the 'Stop' menu.
After the scanning process is finished, you can select one or more of your attached files, and copy them into the desired folder, by using the 'Copy Selected Files To' option. If have large attachments that you want to delete, you can use the 'Delete Selected Attachments' option. Be aware that when you use the delete option, only the attachment file is deleted. The message itself remains on your mailbox.
You can also use the 'Clean Selected Attachments' option to clean most of the attachment content, but without removing the attachment entry. If you use this option, you'll still see the attachment listed in your email message with small file size, but saving this attachment to a file will create a corrupted file.

Inline Attachments

Attachments embedded as a part of the message body are detected as 'Inline Attachments'. By default, OutlookAttachView doesn't displays these inline attachments.
If you can't find the attachments you're looking for, you should try to turn on the 'Show Inline Attachments' option, located under the Options menu.

Control The Filename Format of Extracted Attachment

When you extract one or more attachments from your Outlook mailbox, you can control the way that the attach filename is generated. By default, OutlookAttachView use the following format: %attach_name%.%extension%, which means that the generated filename will only contain the original attachment name and the file extension. However, you can also use the following special variables to format the filename according to your needs:
  • %attach_name% - The original name of the attachment.
  • %extension% - The original file extension of the attachment.
  • %subject% - The subject of the email contains this attachment.
  • %folder_name% - The folder name of this email (Inbox, Sent Items, and so on)
  • %from% - The sender of the email.
  • %to% - The 'To' field of the email.
  • %message_date% - Message creation date in yyyymmdd format.
  • %message_time% - Message creation time in hhmmss format.
  • %message_size% - Attachment size, in bytes.
  • %folder_path% - Full folder path of this email. (For example: Personal Folder-Inbox)
  • %msgdate:[format]% - Message creation date, in any format you need, for example: %msgdate:yyyyMMdd% , %msgdate:ddMMyy%
  • %msgtime:[format]% - Message creation time, in any format you need, for example: %msgtime:hhmmss%

For example: If you want to generate the attachment filename with the subject, folder name, and attach name: %folder_name%_%subject%_%attach_name%.%extension%

Be aware that some of the values are automatically truncated after 64 characters, in order to avoid from over-sized filenames.

Scanning Outlook Attachments of External PST Files

If you want to search an attachment in one or more PST files that are not loaded in your Outlook profile, you can use the following trick:
  1. Go to Control Panel -> Mail and choose 'Show Profiles'
  2. Click 'Add' to create a new profile.
  3. Fill the email account information with faked details (You can delete it afterwards)
  4. After the profile is created, double click on the profile, and in the profile properties, click 'Data Files' and add the desired PST files that you wish to scan.
  5. Also, you can click the 'E-mail Accounts' button, and remove the faked account that you previously created.
  6. In the Mailbox Scan Options of OutlookAttachView, choose 'Allow me to choose the profile' in the Outlook Profile option.
  7. When you are asked to choose the profile, you should choose the profile that you created, and OutlookAttachView will scan the PST files that you added into it.

Command-Line Options

/stext <Filename> Save the list of all Outlook attachments into a regular text file.
/stab <Filename> Save the list of all Outlook attachments into a tab-delimited text file.
/scomma <Filename> Save the list of all Outlook attachments into a comma-delimited text file.

When you use the SaveDirect mode, the attachments list is saved directly to the disk, without loading them into the memory first. This means that you can save a list with large amount of attachment lines into your disk without any memory problem, as long as you have enough disk space to store the saved file. The drawback of this mode: You cannot sort the attachments according to the column you choose with /sort command-line option.
/sort <column> This command-line option can be used with other save options for sorting by the desired column. If you don't specify this option, the list is sorted according to the last sort that you made from the user interface. The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or the name of the column, like "Filename" and "Subject". You can specify the '~' prefix character (e.g: "~Subject") if you want to sort in descending order. You can put multiple /sort in the command-line if you want to sort by multiple columns.

OutlookAttachView.exe /shtml "f:\temp\attach.html" /sort 2 /sort ~1
OutlookAttachView.exe /shtml "f:\temp\attach.html" /sort "From" /sort "To" /sort "Subject"

/nosort When you specify this command-line option, the list will be saved without any sorting.
/cfg <filename> Starts OutlookAttachView with the specified configuration file instead of the default OutlookAttachView.cfg
/start Starts the mailbox scan immediately with the loaded configuraion, without displaying the Scan Options dialog-box.
/extractall Extracts all Outlook attachments from command-line, according to your last settings saved in the default .cfg file, or according to other configuration file that you load with /cfg command-line option.

/ScanOptions.UseSubjectContains <0 | 1>
/ScanOptions.SubjectContains <Subject String>
/ScanOptions.ScanOnlyFolders <0 | 1>
/ScanOptions.ScanFoldersList <Folders To Scan>
/ScanOptions.SkipFolders <0 | 1>
/ScanOptions.SkipFoldersList <Folders To Skip>
