Exchange 2010 Sp1 & Outlook 2010. Corrupt entry in AutoComplete cache. Autocomplete cache is now included in user’s mailbox. Need to list and edit the AutoComplete (Nickname cache) for users centrally. Can this be done in PowerShell or another tool, since it is a part of user’s mailbox? The goal is to find which users have a particular corrupt entry and fix/remove the corrupted entry for just these users. Any suggests?

Hi Nohandyman, Outlook 2010 changes the location of the AutoComplete Cache. It’s no longer an .nk2 file but is now hidden folder within an Exchange Mailbox or a .pst file, depending on the account type in Outlook. However, with the nickname cache in the mailbox, the content now travels with the user. For this issue, based on my experience, Outlook and Powershell do not have the function as you required, maybe you can use other third-party tool to achieve the goal.
