Microsoft Outlook 2010 and Microsoft Outlook 2013 let you add multiple Microsoft Exchange accounts to the same profile. You can add an additional Exchange account if one of the following conditions is true:
This section describes the two scenarios in which unexpected behavior can occur when you use the Outlook feature that lets you add multiple Exchange accounts to the same profile. Additionally, this section provides the steps that you can follow to resolve or to work around these issues.
Scenario 1: The manager and delegate mailboxes are added to the same profileOutlook 2010 and Outlook 2013 let you add your delegate’s account to your own profile and lets your delegate add your account to their profile. However, although there is no warning message or error, this profile configuration is not supported. For example, the following screen shot shows an Outlook 2010 profile that has two Exchange accounts.

In this example, the manager is Marcelo Santos. The delegate has added the mailbox account of Marcelo Santos to his own Outlook profile.
If the manager and delegate mailboxes have to be accessed in the same Outlook profile, follow these steps:
291626The following steps demonstrate two problems that may occur if manager and delegate accounts are added to the same profile by using the Outlook multiple Exchange accounts functionality.

Note In this scenario, you are considered the manager account.
Scenario 2: The mailbox that you add is also added by Exchange Server 2010 SP1 Auto MappingIn Exchange Server 2010 Service Pack 1 (SP1), the new Auto Mapping feature automatically adds mailboxes to the Outlook Navigation Pane if you have Full Access permission to the mailboxes. Outlook manages these additional mailboxes by using a specific permissions set. If you previously configured these same mailboxes as multiple Exchange accounts in one Outlook profile, you may experience unexpected behavior when you send mail by using those other mailboxes. This is because mailboxes that are accessed by using the Outlook multiple Exchange accounts functionality use a different permissions set from those mailboxes that are added by Exchange Auto Mapping. Outlook tries to use both permission sets at the same time. This profile configuration is not supported.
To prevent this issue, use one of the following methods:
Disable Auto Mapping for the shared Exchange mailboxesExchange Server 2010 Service Pack 2 (SP2) extended the Auto Mapping feature to also let an administrator disable Auto Mapping for specific mailboxes. To disable the Auto Mapping feature for specific Exchange mailboxes, the Exchange administrator must use the Exchange Management Shell. For more information about how to disable Auto Mapping for Exchange mailboxes, visit the following Microsoft TechNet website:

Remove the auto-mapped mailboxes from your profileTo remove the auto-mapped mailboxes from your profile, use the Account Settings dialog box. Because these mailboxes are automatically added through Auto Mapping, you do not have to also add them as additional Exchange accounts.
