Using Multiple Accounts for the Same Profile on Outlook
You can sign in to Outlook by using a profile that specifies one or more accounts associated with different delivery stores. For a given session, the NameSpace object has members that maintain and access information for the primary Exchange account, and the Accounts property of the NameSpace object holds information for all the accounts defined for the session's profile.
The NameSpace.Accounts property returns an Accounts collection for the current profile, tracking information for all accounts including Exchange, IMAP, and POP3 accounts, each of which can be associated with a different delivery store. To identify the primary Exchange account in the Accounts collection for a session, look for the account that has the ExchangeStoreType property of the store (that is specified by Account.DeliveryStore) equal to OlExchangeStoreType.olPrimaryExchangeMailbox.
Account.DeliveryStore.ExchangeStoreType = OlExchangeStoreType.olPrimaryExchangeMailbox
The following table compares members of the NameSpace object and members of the Account, Accounts, or Store object depending on whether the session's profile has one account or multiple accounts. If only the primary Exchange account is in the session's profile, use the following members of the NameSpace object.
