I just bought a new iMac and loaded Entourage 2008. I have hosted exchange email through Sherweb.com and have successfully set up my personal email. The only problem I'm having is that I cannot tell Entourage to "constantly" check for new emails. It checks for them about every minute. When I do a test email it downloads almost instantly to my blackberry and to my old Outlook account on my PC... but every time it shows up about a minute later in Entourage. Is there a way to fix this?
