However, some users complain about receiving the message Operation Failed Attachment in Microsoft Outlook. You cannot attach a file to new emails or when you send an attachment to someone on a Windows 10 computer. Some users receive this error message when they open an email message sent to them that contains a Microsoft Word document as an attachment.

The following solutions depend on the cause of the problem and the version of your Microsoft Outlook client. If you are not sure what the problem is, you can follow each method separately and see if it works for you.

What causes the error Operation failed in Outlook attachments?

Conflicting Outlook Add-ons : Add-ons extend the functionality of Outlook, but conflicting add-ons are another story and cause problems like the one described here.

Office/Outlook installation damaged: If the installation of Office/Outlook itself is incomplete, Outlook may not be able to successfully install the attachments.

Problem with the permissions in the Drafts folder: The Drafts folder is the folder where messages are stored to be sent later. Due to a software glitch, many users have received the current error message.

Contradictory/double rules : Rules are automated actions that are performed according to certain criteria. If they are not set up correctly or restrict the attachments, an error message is displayed for the attachments.

Older version of Outlook : To keep up with new technologies, Microsoft releases an updated version of Outlook from time to time. If you are using an older version of Outlook, you may experience many problems.

Outlook works in compatibility mode: In compatibility mode, some of the required Outlook components cannot perform their legitimate operations, resulting in the current error.

Damaged/failed PST file: Outlook needs to access the PST file to perform tasks and if for some reason it cannot access the PST file or the PST file is corrupted, it indicates the problem you are experiencing.

Conflicting uses: Conflicting applications on your system can cause many of the same Outlook issues as the current problem. These applications can be antivirus/firewall applications, etc.
