Microsoft Outlook Attachment “Cannot create file” error message

Had a user call and complain….seriously….they were PISSED

Somehow they were not able to save or open an email attachments in Outlook 2007. They kept receiving the error below

Cannot create file: filename.extension. Right-click the folder you want to create the file in, and then click Properties on the shortcut menu to check your permissions for the folder.

I Google’d the error and came across a fix from Microsoft’s that worked for this situation.  As ALWAYS …be careful when modifying the registry…if you don’t feel comfortable…then you don’t do it….simple as that.  Also, I am not responsible if anything goes wrong.  This solution might not work for everyone but it worked for me.

    Hi, this all worked except I couldn’t find the “Modify” in step 4. (I am using 2007).
    So instead, I copied the address of the folder into the Start/Run address box and that took me to the actual temporary files. From there I deleted the temporary files and restarted Outlook. This solved my problem.
    I was only having trouble opening one specific file from a daily email I received. All other attachments were opening fine. From another post I believe it has something to do with the number of files with the same name that you can have in the temporary folder.

    Hi thank you very much for solution as Brenda says there is a limit in the number of Files with the same name in a temporal folder. It was happening same with me I receive a daily-basis report always with the same name and I’m only deleted the content of Temp Folder, the issue it’s solved now.

    This would however …. when you located the regestery entry in question… Just goto current temp file location and clear the numerous files that are located in there. outlook loves to cache files in there and bever clear them. as a result this funky error occur among other.

    I had the same issue with one of the staff of our company and used the method to resolve it. The thing is I did not have to delete the folder and create a new one and change the path in the registry as suggested.

    My colleague could open all attachments from anyone else or file type but just not from that one company. I realized that the company was sending attachments to my colleague and each time the file had the same name. Over time Outlook 2010, seeing that the file name already existed just kept adding the suffix (1),(2),(3)etc. Once it reach (99) it could no longer save the attachments and that’s when the error messages are generated.

    What I had to do was to create a new folder in the directory just to save the attachments, and move all the old attachments in there. Once I did that my colleague was able to open up the same attachments again from the company.

    So a different approach may be required depending on the situation.
