Exchange coexistense with MSOL (Microsoft Online) O365 and Exchange on primis and the cloud requers federation between your onsite Acitive Directory and the O365 service directory service. Limited to 10K user objects without MS consistent on a per case basis.

Exchange 2003 performance and disk partitions

Because exchange 2003 will read/write in 4k chunks have a default offset of 63 sectors will cause the occational read from the uneven partition size to result in 2 IOPS. This over time will create a measurable, and in large enviroments, unwanted read performance.

Dispar.exe has been integrated into Diskpart.exe (Sever 2003 sp1+?)
diskpart.exe
diskpart> select disk 1 (1 or other disk # obtained from diskmgmt.msc)
diskpart> create partition primary align = 32

There is a good technet blog on this issue: http://blogs.technet.com/b/exchange/archive/2005/08/10/408950.aspx
