Mailbox size restriction

Most e-mail accounts include a mailbox or account storage limit. In fact, in 90% of the case, this limit is breached primarily by the presence of attachments. In particular, this can range from small Kilobytes to large Megabytes, and even in hundred Megabytes.

Moreover, over time, the Sent Items folder is accumulated with redundant attachments. Because a copy of each message that you send is saved underneath it. As a result, this not only fills up the recipient’s mailbox, but also increases the file size of Outlook data file and mailbox.

Nevertheless, the world’s most popular email client – Microsoft Outlook is still devoid of an effective mechanism for mailbox/Outlook PST size optimization.


Should you be archiving emails?

The solution to frequent mailbox limit breach is not ‘Archiving’. But to do away and disconnect attachments from the mail items altogether.

In fact, store them externally from Outlook, and still maintain the hard link between the mail and their associated attachments. Besides, mailbox space is pretty expensive when compared to a local disk.

Moreover, files and documents load up faster from local folder too, than in Outlook. Henceforth, this advantage itself favors the argument, for moving attachments away from Outlook.

Surprisingly, you would have expected Microsoft Outlook would offer a wizard or tool to do just this. In reality, there is no such feature built-in to Microsoft Outlook.


Detach attachments to file system

Attachment Detacher add-in is designed to perform the detachment and storage of attachments, outside of Outlook, with complete user transparency. And yet still offer seamless integration of external attachments to emails in Outlook.

Consequently, it helps you to save precious space on your PST or Exchange mailbox. Moreover, it contributes to making Outlook run much faster with better performance. In addition, it also removes the requirement for constantly archiving duties.

Furthermore, at times when there is a need to move the attachments back to original mail item, like when replying or forwarding, it will automatically re-attach the associated files from the local disk, back to the original email.

Strip down or detach attachments

To strip down and detach attachments from the email item, select it from your Inbox and click the ‘Detach‘ button from the toolbar.

At the same time, leaving behind the hard links of the files in the email itself, for easy retrieval and access.

Re-attach related files back to the email

If you want all the attachments back to the email item, you can simply use the ‘Re-Attach‘ function. This action will put back all the related attachment files from the file folder to the email, in the original condition. As a result, the hard links from the body description will also be automatically removed.

Automatically detach attachments from emails

Don’t want to manually detach attachments from your emails? You can allow the add-in to monitor and track any number of mail-enabled folders and mailboxes for incoming emails. And detach attachments to a file folder and link them up within the emails. All in all, these are done seamlessly within Outlook and users will not even be aware of it.

To achieve this, just navigate to the Inbox or Outlook folder where you want the to apply the automation. And click ‘Folder & Auto Option‘ button. And that would prompt you with a dialog box where you can choose the destination folders (to place the detached files). You will also need to enable the 2nd option ‘Automatically detach attachments when new Outlook item is received‘ under the ‘Automation’ section.
