I am getting error messages in my trusted Eudora whenever I go to delete a file. The message reads: Could not open the file c:\Program Files\Eudora\Mail\Trashbox<wbr />.mbx. Cause: Access permission denied. File may be marked as read only or locked (13). <br />
<br />
I am getting this same message for some of my other mailboxes as well including my inbox. <br />
<br />
I found this message on Google:<br />
<br />
Solution: An e-mail message in the Out mailbox has an invalid attachment. Select Window. The &quot;bad&quot; message should appear in the Window pull down menu. Open the message, review the &quot;Attached:&quot; field header and correct the &quot;bad&quot; attachment line. You may also need to review the Out mailbox. Check the &quot;Attached:&quot; field of any e-mail messages that are still queued. <br />
<br />
I filed all the messages in my outbox figuring that would remove the offending attachment if there were one but I still get the same message.<br />
<br />
I don't know if this is a factor but I have stored probably hundreds of thousands of emails in the mailboxes over the last 15 years. I am wondering if I have pressed Eudora to the maximum with all of the saved messages.
