I'm getting previously read emails downloaded into Outlook. The last was 653 previously read emails so now I have 653 duplicates. What's up? How do I stop this?
Ever since switching to Microsoft office for mac, when I use outlook to retrieve email, I receive a duplicate of every message brought in.  Does anyone have a way of fixing this?
When I send a message, then get a reply, then reply back, my email signature is duplicated? How can I correct this? 

I have my Gmail account whose mail I have forwarded to my hotmail account. The setting on Gmail is that i have kept it as Mark as Read and keep a copy in Gmail and forward one to my Hotmail account.

 

Now when a mail is sent to Hotmail or my Gmail ID, I am receiving 2 copies in total in my Hotmail account. Can anyone help me out with this. Thanks.
