Hi All,

Just a quick question not really a problem. I noticed on out system that whatever machine I log onto and open outlook. it appears to keep all my autocomplete cached can you please advise how this works is it an exchnage feature.

We are currently using Windows 7 ENT, Outlook 2010, Exchange 2010 

In Outlook 2010 + Exchange 2010, the nick name cache is stored in user's mailbox. Outlook 2010 reads the autocomplete stream from a message in the Associated Contents table of the Inbox of the mail accounts delivery store. This hidden message has a message class and subject of IPM.Configuration.Autocomplete. The autocomplete stream is stored on this message in the PR_ROAMING_BINARYSTREAM property (PidTagRoamingBinary Canonical Property). The autocomplete data may be temporarily cached in an autocomplete .dat file located in %USERPROFILE%\AppData\Local\Microsoft\Outlook\RoamCache. However, the .dat file is only a cache and is not used to write back to the delivery store when the user exits Outlook 2010.
