Sometimes there are conspiracies hatched by technology in an effort to make life difficult for custodians. The good thing about this custodians gets to learn a few more tricks if they invest some time in understanding these conspiracies. Recently, a data centre switched malfunctioned and caused a network outage. The outage broke a few things and corrupted one of my Lync 2010 address book files. My lync users started getting weird and garbled contacts when searching on Lync. No matter what i did, the garbled contacts stayed. I turned to my event log on my front end pool for the affected users.

Upon checking the Lync events i stumbled upon one event which indicated that Lync address book service could not write to a specific file.

Who has been here?
