Update MS Outlook

Users who are using older versions like Outlook 2003 and 2007 may face delays in opening attachments. The newer Outlook versions can handle more emails and their large-sized attachments more effectively than the older versions. So update your Outlook to the latest versions to get rid of slow email attachment opening problem.

Run Outlook in Safe Mode

Anti-virus programs or firewalls may scan emails and cause issues while opening attachments. You can solve this issue by running Outlook in safe mode. This can be done by running outlook.exe /safe in the Run command interface.

Check the Size of Outlook Data Files

If you are experiencing delays while opening Outlook attachments, one possible cause may be that your Outlook data files are too large. This can happen if you have a lot of email messages or other Outlook data stored in its folders, and it can affect the speed at which Outlook opens attachments.

To check the size of your Outlook data folders, open Outlook and go to File > Account Settings > Data Files. You should see a list of all the Outlook data files on your computer, including their file sizes. If any of these files are particularly large, you may need to take steps to reduce their size or archive them to free up space on your hard drive.

Disable the Antivirus Programs

Another potential cause of Outlook attachment issues is antivirus programs running in the background. These programs can sometimes interfere with Outlook, causing delays or even crashing the program altogether.

If you suspect that your antivirus program may be causing problems, you can try disabling it temporarily to see if this resolves your Outlook issue. Note that it is important to have an antivirus program installed and running on your computer, so you should only disable yours as the last resort. Some possible options include using a different antivirus program or installing Outlook-specific security features such as Outlook Protected Mode.

To disable your antivirus program, open Control Panel on your computer and look for an option to turn off or disable antivirus. Alternatively, you may need to consult the documentation for your antivirus program to find the specific steps for disabling it.
