Trapping your favorite exceptions

Like most folks, I hate errors. As a scripter, I hate seeing blood on the screen–to me, it means failure that I didn’t anticipate.  When you’re trying to put tools out there for other folks to use, nothing toasts your peer’s or customer’s confidence like a tool that doesn’t fix itself or errors out without…

Update to the “Find Duplicate Address” tool

Last week, I saw some internal discussion about trying to locate the source of a duplicate object error on-premises.  While an advanced administrator will be able to figure it out by looking at the Connector Spaces for connected directories, it’s not necessarily obvious to a lot of people (especially if you’re not experienced with our…

Using “Restore-RecoverableItems”, or “how I saved my own bacon”
