I had a problem today where a customer could not attach a particular PDF document to an email in Outlook 2003. They had been attaching the document fine earlier in the day and then all of a sudden it just would not attach. When selecting the document the following error would appear: -
"Can't create file: 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 tried copying the file to a new folder and the problem still persisted. Other documents were fine, it was just this single one. I then did some searching about and discovered that the problem lied with Outlook's temporary files. To solve the problem I did the following: -
1. Open REGEDIT.EXE and go to Edit -> Find... In the Find dialog box type "OutlookSecureTempFolder" without the quotes and locate that registry key.
2. That key will contain the actual folder location, and will look like:
C:\Documents and Settings\%USER_NAME%\Local Settings\Temporary Internet Files\OLK#\ (where # is a random letter or number)
3. Copy the location of that folder.
4. Click on Start -> Run... and paste the folder location from step #4 then click OK.
5. Windows Explorer will open that folder. Please, delete all files present.
6. Restart Microsoft Outlook and you should be able to open your attachments.
After doing the above the file attached fine no problems!!
