The Microsoft Outlook Attachment Extractor is a small software program for the Windows operating system that can extract and remove email attachments from selected Microsoft Outlook folders. Extracting in this case simply means to save the attachments of a selected Outlook folder to another location on the computer system. Removing on the other hand means that the attachments will get unlinked from the email messages which will free up the space on the hard drive that the Outlook mails and profiles reside on.

This does not have to mean that the attachment cannot be opened from the email anymore. It is possible to remove the attachment from the Outlook folder completely, to replace it with a link pointing to the new location of the files or to replace it with a text reference in the email attachment.

Several options are available to configure the process in detail. It is for example possible to only process attachments that have a specific extension or those that are larger than a certain file size. The destination folder for the attachments can be selected as well as rules on how to process already existing files.

The Outlook Attachment Remover can also be used to add the removed attachments to the email messages again at a later point if the need arises.
