Question about Outlook Express

I have a staff member with Outlook on her MAC. She has an IMAP account. There are phantom outbound messages that are preventing her account from sending new messages. However, all solutions lead back to deleting those messages from the outbox. One problem: cannot find the outbox folder! I've expanded every folder she has and it is nowhere to be found.

Any suggestions?

I have a MacBook 3.1 with OS 10.6.8 Leopard with MS Office 2011 installed.  I had so many problems with Verizon email that I changed over to a gmail account. Verizon was not happy about that because I also changed my cell phone service. I finally got the new email account working for about 2 weeks, when

Outlook crashed after the 14.6.1 update.  Now Outlook cannot open.  At first Outlook provided the message that there was a Daemon Error and that it had to close. I notified Microsoft of the errors several times. Now, after several efforts and advice from others, on line, it doesn't open at all.  Just a flash of the icon.  What are my options to fix this?  Luckily I have backed up my data on a weekly basis.

Under El Capitan, I cannot print anymore e-mails in Outlook for Mac (Office for Mac 2011). After giving the printing command, the button is vibrating, but the window to select the printer is not popping up.

This is only the case for e-mails. I can print agenda and contacts in that Outlook package. I also can print Word, Excel and Powerpoint documents.

After I upgrading to El Capitan, it was possible to print e-mails, but after some weeks it became impossible.

For a week now I have been unable to send and receive email using Microsoft Outlook 2011 for Mac. It happened suddenly, and I can't detect a reason for it. I've removed all emails that were trying to send (but were sent to 'draft' when they couldn't go). I've tried creating a new identity and that also doesn't work. I've tried installing fixes, they don't help (or won't install). I am receiving the same emails from my work's exchange server on my phone (so know that this is working fine). I've turned the phone off, to see if that helps, but it doesn't. 

I really need to sort this out as working through Outlook Microsoft Access is a pain.
