Final Words
I have been having this issue for a while now and it has been getting worse and worse. I have tried different Outlook versions, different browsers, and even different computers. I even tried resetting my computer but that didn’t help. I think it is because Outlook is not able to open attachments properly. Can anyone help me out?
