As you may have read from my previous message, I'm having a problem sending basic e-mail over SMTP from Outlook 2010 to Exchange 2010. The problem doesn't, however, appear to be anything to do with Exchange after all, but a problem within Outlook.
I'm in the process of migrating from Exchange 2007 to Exchange 2010. I thought Microsoft would make this fairly easy (for their benefit as much as the users'). Oh how wrong I was.
Today I've been looking into what's involved in upgrading our Exchange 2007 server to 2010. At first this seems like a simple request, but it turns out it's actually incredibly complicated.
