I have a situation where the …OutlookRoamCacheStream_Autocomplete file for my Outlook keeps being reset to a new, empty file every day or two. The new file is empty and contains no addresses. I have had Outlook reset the file. I have also renamed the RoamCache folder so that a new one was created, with its files, but the file reset continues. I am on my sixth file since Dec. 20th.
I am not connected to an Exchange server and use Windows 7 SP1 on 64 bit.
Do I need to reinstall Office 2010 to fix this? It worked fine for several months.
