I am unable to send email from my hotmail account that i set uo on my new Htc one x phone. The first time I set up the account i was able to send, but after a few hourse i wasnt able to send it.  Every time  i go to the settings and manually disable and then enable the sync mail option also it does not work. When i deleted the account and set it up again, it worked the first time, but I cannot send emails after a few hours. I can receive emails but not send emails. Has anyone else encounterdnthis issue? I see a few recent posts  on similar topic but couldnt see any resolution posted that is visible to the public. can you please let me know if this is a known issue and whaat the work around is. thanks,

I keep recieving the same email message from an unknown source...I block the message (that goes to my junk mail, thank God, because it's vulgar!), but it keeps coming back because it has a different return address each time!  When I try to reply to tell whoever this is that I'm not the person they are writing too, (obviously she thinks she's writing to a man), I get the "undeliverable message". So I have no choice but to keep blocking the sender, yet I keep getting the message with a new return address. I have recieved 4 so far...Please tell me what to do. How do I prevent this from happening in the future?

Emails that my family, friends, professors, & work are being bounced back.  I use my email a lot to contact my school professors as this is the only way they can contact me because my school is an online college. My email inbox is not full as I check it everyday or two.  I also empty my junk mail and delete folders on a regular basis, so as not to overfill my email.  My email is not blocked or locked.  Not sure what all else I am missing as I just learned of this problem.  Can you help me to continue receiving emails?  I really need to be able to receive all my emails because most of them are important for my work and my education. 
I am upgrading a computer from Office for MAC 204 to Office 2011.  I currently use Entourage for my email .  Will the installer transfer all my saved mail from Entourage to the new version of Outlook?
