T.F.
It sounds like there is more to the story that you may or may not be aware of.
I don't know if anything I say can help you but maybe you can get some ideas of what to do..
My "flag" went up when you mentioned the switch from direct deposit to paper check...HUGE RED FLAG here.....the company is in financial trouble.
I don't know if you have a case or not but one thing I have ALWAYS done is have a back up of all my info (CYA file). I keep a file in a separate location that can't have access blocked..... a yahoo, hotmail, etc address. I continue to back everything up elsewhere so I have any proof if I need it. I've never needed it but it sure is nice to have it.
Were you aware of a 90 day trial period? Did you sign a contract? Were you on the health plan (they are required to offer it to you through Cobra). I would call the TX Employment Commission and ask questions.
It sounds weird to me that they are holding your Outlook "hostage". I would not fork over the laptop or blackberry until I got some answers.
I'm sorry you are going through this. I don't have experience with it myself. This company does not sound like it is a well run place to me.
