Email not working

[Guest ChaosLegend]

Yea, all of a sudden I can not create new emails. It just redirects back to the inbox. Replying does not work either. Same issue if I am using tmail.exe for SMSing. I think this and the fact that my SMS unread count is also not updating are linked. Is it possible my tmail.exe is somehow corrupted? Is there a solution for this? I can still receive emails and SMS though.

Thanks a lot.
