This post is to clear up any ambiguity regarding the recommended Page File settings for an Exchange server. If you search online for a solution you will find all sorts of answers (and of course if it's on t'internet then they must be right).
The short answer is to set the minimum and the maximum to the amount of RAM plus 10MB.
That answer can be found posted by Microsoft here:

It states there - "As documented in the Exchange 2007 System Requirements and Exchange 2010 System Requirements, the recommended paging file size is equal to the amount of RAM in the server plus 10 MB."
It also states - "To prevent page file fragmentation, we recommend that you set the paging file size initial and maximum values to be the same value. If you reduce the size of either the initial or maximum page file settings, you must restart your computer to see the effects of those changes. Increases typically do not require a restart."
