I noticed that almost 100 repeats of 2 particular emails I sent a few days ago keeps appearing in my "Sent" box - there was 5600 emails clogging up my account and restricting other emails coming in. outlook keeps telling me my account is growing too fast. upon deleting all I noticed later more appeared. These seem to be repeating every few minutes.....I just deleted all 5600 and within 10 mins there were another 20 that instantly appeared again...please help this email account is very important for work purposes......
