• Click Start, click Run, type regedit, and then click OK.
• Locate and then click the following registry subkey:
• HKEY_CURRENT_USER\Software\Microsoft\MSCRMClient
• Right-click MSCRMClient, point to New, and then click DWORD Value.
• Name this DWORD value "DelegateMailboxEnabled."
• Double-click DelegateMailboxEnabled.
• In the Value data box, type 0x00000001.
2. Assign enough permission to the Sales Manager in the Assistant's Outlook.
• On the Sales Manager's machine, Open Outlook, Click Tools=>Options, under Delegates tab, click Add.
• Select the Assistant's account, then click OK.
• Make sure both have Reviewer rights on Inbox, Contacts, Tasks, and Author rights on Calendar.
