We use Outlook 2010 and 2013 connected to Microsoft Office365 (corporate accounts). We imported a big address book. Every account has access to it, no problem there.
I search a way to use auto-complete from this address book when people type an email address.
The usual trick is: create a new email, add every contact to the "A" field, then close the email.
It works as long as Outlook remains open. Once Outlook is restarted, only the old auto-complete remains.
Is there a way to "import" contacts into the auto-complete cache ?
We tried what appear to be the usual trick: manually remove the Stream_Autocomplete.dat file then restart Outlook. Then Outlook recreate the file. But in our case the file is not recreated and the problem remain the same.
We also tried to clear the autocomplete cache (from Options/Mail/...), uncheck the use of autocomplete, restart Outlook, recheck autocomplete. This hasn't solved the problem.
