Because you must use another program to send it - like Outlook.
Just do it the correct way: save the ppt file on your pc, close PowerPoint, open your mail program (Outlook or whatever) , compose a new mail , attach the ppt file to it and send the message to its destination.

Please check the size of the attachments and the extension of them. Outlook does not allow any .exe or any programs as an attachment.

As an old Outlook user (for over a decade). I ever met similar error with my Outlook PST files before and got it solved with this Outlook PST repair software, the software extracts & restores those inaccessible Outlook items in a new .pst file and enables complete Outlook data recovery. If you want to take the most effective way, then try that program. Hope it helps too with your case.

If you are unable to open any attached file in your incoming mail and are using Microsoft Office 2007, run registry editor (regedit.exe) and scroll to the following location:

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security

Copy the contents of the "OutlookSecureTempFolder" key and paste it in the Windows Explorer to open the OutlookSecureTempFolder. Delete all files in this folder and then run Outlook.

This location can not be browsed to and can only be found from the registry as it is different for all users. e.g. for myself it is as follows:

D:\Users\keekus\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\R34DKK8O\

For earlier versions of Microsoft Office, you may find the "OutlookSecureTempFolder" in these locations:

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security

or

HKEY_CURRENT_USER\Software\Microsoft\Office\10\Outlook\Security

Close outlook and search for *.SRS files once you find the files delete it open Outlook

srs files are for sending and recieving mails in Outlook

Have you tried the repair option in Outlook? From the help menu, you can choose Detech and Repair. Also, you can choose to repair all of Microsoft Office from the Control Panel, Add and Remove Programs, find Microsoft Office, and click change. Then You can choose to repair.

Try saving the document to your local drive first, then send the file as an attachment. When the file is opened from your Outlook, it resides only as a temp file while you are viewing it, then to try to send that temp file, it causes issues with outlook. Save the file first, then send it, but don't try to send the file from the temp view whilst opening the file that is still in another e-mail

Hi Mr jones24,

Try zipping the file before you send it. I think Outlook has spotted that your trying to send a database file and is blocking it. When you zip it, outlook might not be able to peer through the zip file to see. I know it works on older versions of Outlook.

You can use the inbuilt Microsoft "Compressed Folder" zip tool, just right click on the file within windows and select "Send To -> Compressed "Zipped" Folder"

Or you could try 7zip, which is an excellent free zip utility
