Outlook 2010 with Office 365 - Contacts don't appear in Autocomplete

paulc2000 used Ask the Experts™
Hi all,

Our business just moved from Yahoo Bizmail (generally used through the browser) to Office 365 with Outlook 2010.  Each user exported their contacts from Yahoo to a CSV, and imported the CSV into Outlook.  That's all fine, the contacts are all there in Contacts.  I expected that this would be enough for these contacts to appear in the Autocomplete when typing in To:, Cc:, etc.  However, it doesn't work, no matter what I try.

The closest I've got is to compose an email and add all users in Contacts to To:, then close and discard the email.  These contacts how appear in Autocomplete, but disappear again once Outlook is restarted.  I don't understand why this is so difficult...

Does anyone have a foolproof method, please?  We're not upgrading from 2007 to 2010 or anything like that, so most of the suggested fixes on the web don't apply.

In my case, I'm using Outlook 2010 on Win7.

Any suggestions welcome!

Found a workaround:

Create a new email.
Select all your contacts (from To...)
Disconnect your Internet connection
Send the email (because you don't have Internet access, the email is going to sit in the Outbox)
Close Outlook
Open Outlook
Delete the email that was sitting in the Outbox
Close Outlook
Get the Internet connection active again
Back to Outlook and autocomplete is working for all your contacts
