I thought I had already posted a question on this subject but I cannot find it so bear with me if I am repeating myself.....here goes

I know how to find my blocked senders list, like I know where it is but it shows empty. I used too send tons of rubbish to BSL, suddenly it is empty. I wish that were all but its not. If I send something to BSL it disappears into the bowels of my Pee Cee. Nothing finds its way in my BSL UNLESS I type it in manually. Whoever can solve this problem goes straight on my Christmas Card List and could possibly get a Knighthood. ........as a bonus

Hang on Chloe I have to decipher your reply, being a Pee Cee Virgin perhaps you can explain what OWA means. What is admin privilege? What I do know I changed nothing in my system or Outlook .......I will get back to you. 

Hi,

Sorry for the lack of explaination. OWA means Outlook Web Access. It formats like this: This Article explains very detailly on how to access OWA.

For starting your Outlook with Admin Priviledge, you can follow this step:Hold ctrl+shift, meantime, click Outlook Icon.

Let me know the result, thank you.
