Reasons for Microsoft® Outlook 2007 blocking e-mail attachments and ways to resolve this issue
What causes Microsoft Outlook 2007 to block e-mail attachments? What are ways to resolve this issue?
Hackers can easily insert malware and viruses into attachments of e-mails. In order to safeguard a system from viruses, Microsoft Outlook 2007 blocks such suspicious e-mail attachments. Microsoft Outlook 2007 refers to such attachments as Level 1 attachments and so the user is not allowed to open or save these attachments. Even if the user is sure of the sender, Microsoft Outlook 2007 does not allow the user to access the mail, thereby creating inconvenience for the user. Thus, Microsoft Outlook 2007 provides security to the system by blocking suspicious mails, but on the other hand a user finds difficulty in accessing important mail even though they are not infected. Yet there are methods to access such uninfected important mails.
Following are the tips to fix the issue of e-mail attachments getting blocked by Microsoft Outlook 2007:
- Using file compression utility
- Rename the file
- Method to unblock the attachment
Using file compression utility
If you do not have server or FTP site, then ask the sender to compress the file. This compressed file will have a different file name as its extension, and Microsoft Outlook 2007 will not block these attachments. As a result, the new attachment will not be blocked, as their file name will not seem to be a potential threat.
Rename the file
If the compression technique is not available, then ask the sender to rename the file name extension and resend the attachment so that Microsoft Outlook 2007 does not consider it to be a potential threat and block it. After receiving the renamed file and saving it on the system, the user can revert to the old file name extension and use it easily.
There is also a different method to unblock blocked e-mail attachments. Initially, users need to close Microsoft Outlook 2007 window if it is open. Then in the Run box of Start menu you need to type 'regedit.exe'. After typing in the Run box, you need to navigate to "HKEY_CURRENT_USERSoftwareMicrosoftOfficeXX.XOutlook", where XX.X stands for version of Microsoft Outlook. In that location, users can create a new string value key, edit the key and enter the attachment extension that needs to need to be unblocked. Then the user needs to click on 'Ok' to save the value and then exit regedit.
