We recently migrated a handful of people using Mozillia Thunderbird email to Exchange Server 2010 and Outlook 2010 and am having troubles with contacts not auto populating when you type a new email.
We exported each thunderbird client email contacts to CSV format. Then , in outlook we used File/Open/Import in outlook 2010 to bring the csv contacts in to Outlook.
The contacts now appear in the address book under email address/contacts. and they appear when you click "contacts" in the left pane in outlook.
The problem is that the autocomplete for these contacts does not function when I type in the To field when tying an email. Only the local domain contacts in the global address list appear.
I can manaully select all these contacts and put them in the To field and hit ctrlK to resolve all the names. This will make autocomplete function fine for all contacts until the employee closes outlook.
Once outlook is closed and reopened, the contacts no longer autocomplete.
