MS Office documents, which are frequently provided as attachments in emails, can be opened within Outlook using the Outlook preview feature. It is also not confined to Microsoft software; one can open a text or pdf file within Outlook. It is not necessary to launch the required application independently to view the contents of the uploaded file.
Without a doubt, the preview tool in Outlook is a really useful and helpful feature. As a result, it does not always function as planned. Outlook occasionally takes too long to preview a file and occasionally produces an error. The problems with preview features can vary. It may be as easy as a pop-up window that says, “The file cannot be previewed since no previewer is installed for it.” It can also be as unclear as Outlook taking ages to preview a file and without displaying any error or diagnostic message at all.

To save the changes, click OK. - If you are unable to modify it, delete the old item and create a new one for the application that is causing you problems.
Analyze your Windows Firewall settings.
Although it is unimportant, enabling Windows Firewall has assisted many users in resolving the attachment problem in Outlook. The Windows Firewall blocks unauthorized access to a program that can disrupt the system’s workflow.
Follow these simple steps to guarantee that your system’s Firewall settings are enabled:
- Select Settings from the menu that appears when you right-click the Start button.
- Continue to Update & Security > Windows Security > Firewall & Network Protection.
