Service Pack 3 for Exchange 2010 has been released. The SP3 was probably most eagerly awaited for the migration or coexistence with Exchange 2013.

Powershell: List overlong file paths

Overlong file paths can become a problem during migrations and backup/restore processes. A file path must not normally be longer than 260 characters. However, sometimes this limit is exceeded. This small Powershell script can be used to identify such long paths: #Directory or volume to be checked: $Directory = "D:\Shares" #PPath to CSV file for ... Read more
