problems opening emails

Never had a problem opening emails before the "upgrade" to outlook. Now, even on the computers at work, I have to wait a few minutes or hours after several tries to come back to the website to finally open emails.  This is ridiculous, obnoxious, and unprofessional since this is how I communicate with other potential employers. My network is on a secured line, my account is under https. There have been update after updates on my home computer. I even recently did a factory reset on my computer. No matter what computer I use, I have the same problem several times a week. I don't even know if this is even worth letting you know about since it may be a while before I can open the response. I've also had several updates to my computer since last week. I'm operating off IE9. I am able to delete the emails and move them by highlighting the email and right clicking a menu, but opening them is out of the question. This is beyond frustrating! Please fix!
