I am using Outlook 2007. This morning when I logged in none of my new emails have been downloaded are showing in my outlook inbox. I have about 5 various email addresses and none of them show any "new" emails? Can anyone help.

How do I send a large group an email in Outlook? I've tried to create a group so that I can then distribute the email with one click, but I can't figure out how to do it. I'm pulling my hair out. Been working on this all evening! I've created a category with about 300 names, but then what? It doesn't show up in the options when I try to fill the "to" space.

Okay here's the thing: I use a windows machine in the office that has Outlook 2003 installed.

When I work from home, I use a mac and use Microsoft Outlook Web Access on a browser.

Now, I noticed that the desktop client downloads all the messages in my mailbox and stores everything locally.

This means that accessing my mail through Web Access from home or where ever will display only the newest messages and I cannot reference emails that have already been downloaded by the desktop client.

Also, from a contingency standpoint: Hard Disk Crash = Epic Fail.

I know that there's a "Leave Messages On Server" option for POP3 accounts. Is there anything similar for an exchange account?

Or is there another way of doing it?
