Reasons and Fixes for Cannot Open Attachments in Outlook
This section will combine both causes and solutions. It simply means that the causes of the issue of attachments not opening in Outlook will be discussed with their practical solutions explained:
1. Unrecognized File Format:
The first major reason why you may not be able to open an attachment in outlook is that the file is in a format that your computer cannot recognize. More so, it could be that your system does not have the software necessary for opening the file format. For instance, if you have not installed an app such as Adobe Photoshop or the like and you receive a mail-in the image format .psd, you cannot open it.
What to do:
- Get the sender to resend the file as an attachment in a format which your computer system can access
- Install software that can open such a file format. This second option is advisable in cases where you will be dealing a lot with this particular file format
2. Bad File Association or Problem with Program
Sometimes you may have the right program for opening a particular file format but still face this error. It implies that the file is not associated with the right program. You can change the program to a program that works for you.
What to do:
- Save the attachment to your local drive instead of trying to open it directly from the email sent to you
- Open 'Explorer' or 'My Computer'
- Right-click on the file that has been sent to you as an attachment, then choose 'Properties'
- Hover on 'Opens with'. Here, choose 'Change' to see different programs from which you can choose. Click on the program you wish to use for opening your file and tap 'Apply' or 'OK'.
- Can't find your preferred program? Do not worry, just tap the 'Browse' option, locate the .exe (executable) file of the program on your PC and choose 'OK' to make the program your default attachment opening program
- If you want to use this particular program to open all your attachments going forward, tick the box beside the option 'Always use this app to open' and select 'OK'
3. Antivirus Programs Preventing
Some antivirus programs you have installed on your system may be the reason you cannot open your attachments in Outlook. How does this work? Antivirus programs work to secure your system from all incoming data to your PC. Attachments are part of such incoming data and so in the course of doing their work, the antivirus programs may stop you from having access to your attachments. Simply disable your antivirus in this instance to check for sure if they are the reason why you can't open the attachments or not.
What to do:
- Go to the 'Windows notification area' and locate the antivirus you wish to disable. The programs usually appear as icons
- Right-click the program's icon and choose 'Disable', 'Shutdown', or 'Stop', depending on the program settings
- Alternatively, open the program if necessary and use its menu to disable
4. Compressed File
Files are usually compressed into formats that make it easier for transfers, especially if the files are very bulky or large in numbers.
What to do:
- First, save the compressed files from your email
- Use any file extractor that will work on the particular zipped folder to decompress the files before you open them. There are several decompressors available online such as Winzip, Winrar, 7Zip, etc. Make a choice and follow the app instructions to decompress your ZIP or RAR files
5. The sender has an Apple Computer and You have a PC:
This is self-explanatory as the attachments created in a different OS from yours will cause a problem. Thus, if the person sending the attachment to you uses an Apple device and you use Windows, you may encounter difficulty opening such attachment. The solution to this is simple:
- Inform whoever is sending you a mail attachment that your OS is Windows hence they should save their attachment in a format that is compatible with Windows before sending to you
6. Corrupted File
If you receive an already corrupted mail as an attachment, you cannot open it because of the damage. Files become inaccessible if they have been infected with one virus or another and have thus become corrupted. Therefore, you have to do some checks so you can end up with an uncorrupted file.
What to do:
- Ask the sender to confirm that the file is opening on their system
- If it is not accessible, then the problem is from the source location. Thus, the sender should create another file that isn't corrupted before resending
7. Outlook Add-ins
Outlook add-ins form much junk and end up preventing outlook from performing properly. You may discover that the add-ins that form part of your outlook are the reason you cannot open attachments.
What to do:
- Launch Outlook
- Follow this path: 'File' > 'Options' > 'Add-ins'
- Select 'COM Add-ins' under the tab 'Manage'
- Just beside 'Manage', you will see the 'GO' button, select it.
- Untick the boxes beside the add-ins and click 'Ok' once you have disabled them all
- Close and re-open Microsoft Outlook to see if the attachments can now be opened
