Why are my sent messages not saved to the sent folder?

Message was sent but not saved in your Sent folder due to unusually heavy activity from this mailbox.?

• Hello, Yahoo have blocked my organisation e-mail box [email protected] about three days ago. I don't see any reasons why. W do often use this box and we log from difference computers. Also there will by lots of new messages coming because we work intensively a lot. At the moment we can't do it. No e-mail can't come to address [email protected]. It is blocked. We also have problems sending messages from that box. ("Message was sent but not saved in your Sent folder due to unusually heavy activity from this mailbox.") Please, unblock or solve my problem. Best, Bartlomiej Matuszewski

• Answer:

  If your account has been sending out large emails or a lot in a short period of time, then it would send up a flag that it may be spamming. Yahoo has been trying to cut down on the spammers. Give it some time before you try again. You could clear the cache and see if that helps. Click Tools, Internet Options. Delete the cookies, temp files and history. Click Ok and restart the computer. Sometimes that helps. If not, you will have to wait until Yahoo lets you.
