To configure multiple Microsoft Exchange Server e-mail accounts for a Microsoft Outlook 2010 profile, follow the steps in this article.

  • Modify or remove Exchange accounts on a profile


In Outlook 2010, you can add, modify, or remove multiple Exchange Server e-mail accounts to an Outlook profile the same way you can for other e-mail accounts by using the Office Customization Tool (OCT). Without any additional configuration, Outlook 2010 can connect to up to ten Exchange accounts from a single profile.

Individual users can add additional Exchange accounts to their Outlook 2010 profile within Outlook 2010. To do so, users can either click the File tab, click Account Settings, and then click Add Account, or use the Windows Control Panel Mail module. They can also remove Exchange accounts on their profile. For more information, see Add or remove an e-mail account (


  • Delegate accounts are not supported in profiles that have multiple Exchange accounts. Users who have delegate access to a mailbox must keep that account in a separate profile from any other Exchange account.

  • In Exchange Server 2010 Service Pack 1, the new Auto Mapping feature automatically adds mailboxes to the Outlook Navigation Pane if you have Full Access permission to them. Outlook manages these additional mailboxes by using a specific permission set. This might cause unexpected behavior if you also have these mailboxes configured as additional Exchange Server accounts in one Outlook profile. To prevent problems in this scenario, you will have to change your Outlook profile so mailboxes that are added through the Auto Mapping feature are also not manually added to the same profile. Use the Account Settings dialog box to remove these additional Exchange mailboxes in your profile. If you do not remove the manually added mailboxes from your profile, Outlook attempts to use the permission sets from both the auto-mapped account and the account setup by using the multiple Exchange Server accounts feature at the same time.

  • If you use the Exchange Server Security template to configure security options for Exchange accounts, the Security form settings for the first account added to the profile (the legacy account) will be used for all the accounts added to that profile.

Before you begin

Before you begin deployment, review Planning overview for Outlook 2010 and Office Customization Tool in Office 2010 to determine which settings you might have to configure for the Exchange accounts. The following three articles describe how to configure specific Exchange account features by using the OCT.

Add multiple Exchange accounts to a profile

Use the following procedure to add multiple Exchange accounts to an Outlook profile.

To add multiple Exchange accounts to a profile

  1. From the root of the network installation point, run the following command line to start the Office Customization Tool: \\server\share\setup.exe /admin

  2. To edit an existing customization file (.msp), in the Select Product dialog box, click Open an existing Setup customization file. Or to create a new customization file, select the Office suite that you want to customize, and then click OK.

  3. In the Outlook area, click Outlook profile. Select how you want to customize profiles for your users. To change an existing profile or to add a new profile, choose Modify Profile or New Profile.

  4. To add and configure new and existing accounts, click Add accounts, and then click Customize additional Outlook profile and account information.

  5. To add an Exchange account, click the Add button.

  6. In the Add Accounts dialog box, select Exchange, and then click Next.

  7. In the Exchange Settings dialog box, enter an account name and the name of the Exchange Server computer. If you want to identify the user by using a specific value, enter a User Name. Otherwise, leave the default %username% value for the User Name. Each user’s account information in the Active Directory directory service will be automatically populated for the profile.

  8. If you want to change an existing Exchange account in a user’s profile, select the Overwrite existing Exchange accounts check box.

  9. Click More Settings for additional Exchange configuration options such as Cached Exchange Mode and Outlook Anywhere, and then click OK.

  10. When you are finished, click Finish.

  11. To add an additional Exchange account, repeat steps 5-10.

  12. If you are creating a new profile, add the Outlook Address Book account to the profile. This account allows you to use the Contacts folder in your Exchange mailbox as an address book when you create e-mail messages.

  13. After you have finished all your customizations, save the customization file (.msp) and exit the OCT. Put the .msp file in the Office installation source \Updates folder. Install the Microsoft Office 2010 from the original installation source.

Modify or remove Exchange accounts on a profile

You can easily modify or remove an Exchange account from a profile by using almost the same procedure as previously described in Add multiple Exchange accounts to a profile. In step 5, highlight the Exchange account that you want to modify or remove from the profile, and then click either Modify to modify or Remove to remove the account. Then, finish your customizations and save the customization file (.msp).
