The autocomplete function in Outlook (when you start typing and it auto fills the email addresses) just will not work on this one mailbox. I have tried everything I can imagine including:
- Creating a new profile
- Ensuring all of the boxes are checked in the Options > Send mail settings
- Putting in both Cache and Online mode
- Moving the datastore where the Mailbox is located
- Renaming the Roamcache folder in the program data folder
- Renaming the Autocomplete .dat file
- Creating a new windows profile
- Trying both Office 2010 and 2013
- Trying on different computers
And the kicker, all of the autocomplete items are in OWA. I do not want to try emptying the "Empty Auto-Complete List" for obvious reasons. The infrastructure setup is Windows 7 Pro 64bit with Office 2013 Pro 64bit. The server is Windows 2008 R2 Standard with Exchange 2010 SP2. Everything is patched and up to date. I know that .nk2 files live on the server now with Exchange 2010 and the fact that I can see all the autocomplete entries (ones not in the GAL) makes me think something else is going on here.

So ultimately, I used NK2Edit from Nirsoft to export the AutoComplete entries to an .nk2 file. Then within outlook, I emptied the autocomplete entries from within outlook. Lastly, I put the .nk2 file in the c:..\Roaming\Outlook folder and ran "Outlook.exe /importnk2" and it imported all of the autocomplete entires back into outlook. Must have been a corrupt entry. Extremely annoying.
