Consider the following scenario. A user sets up multiple accounts in Microsoft Office 365 by using Microsoft Office Outlook 2007. For example, the user sets up his or her Outlook profile to connect to one account through MAPI and another account through POP3. However, the user receives Send/Receive error messages.
Outlook 2007 returns a failure message when it tries to download the offline address book for the non-MAPI account.
To fix this issue, set up the All Accounts Send/Receive group in Outlook 2007 not to download the offline address book. To do this, follow these steps.
In Outlook 2007, on the Tools menu, point to Send/Receive, point to Send/Receive Settings, and then click Define Send/Receive Groups.
Select the group name that's named All Accounts, and then click Edit.
Click to clear the Download offline address book check box for all non-MAPI accounts, and then click OK.
