So usually after a few quick googles things like this can be resolved in a few minutes, but for some reason this one has escaped both myself as well as another senior engineer. Here is the setup. 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.
Any help with this would be amazing.
