This may occur when one of the following conditions is true:
- Encryption between Outlook and Exchange Server (2010, 2007 or 2003) is disabled by a setting in the Outlook profile.
- You are connecting to Microsoft Exchange 2013 or Office 365.
If connecting to Microsoft Exchange 2010 and earlier
To work around this problem, enable RPC encryption between Outlook and Exchange. To do this, follow these steps:
- In Control Panel , open the Mail item.
- Click Show Profiles .
- Select your profile, and then click Properties .
- Click E-mail Accounts .
- Select the Microsoft Exchange Server account, and then click Change .
- In the dialog box that contains your mailbox server and user name, click More Settings .
- In the Microsoft Exchange Server dialog box, click the Security tab.
- Check the Encrypt data between Microsoft Outlook and Microsoft Exchange check box as shown in the figure below, and then click OK .
If connecting to Microsoft Exchange 2013 / Office 365
Connections to Microsoft Exchange 2013 use Anonymous Authentication, which does not support encryption, and the Encrypt data between Microsoft Outlook and Microsoft Exchange check box will be unchecked and disabled. Outlook 2007 will be unable to honor the SCL -1 from Exchange.
The workarounds available for Outlook 2007 users connecting to Exchange 2013 are to:
- Add the full email address of the sender to the Safe Senders list, using the following steps:
- From the Actions menu, select Junk E-mail.
- Select Junk E-mail Options.
Note: If instead, you try to use Add Sender to Safe Senders List for an internal address in step 2, you will receive the following error message.The e-mail address for this sender is internal to your organization and cannot be added to this list.
- In the Junk E-mail Options dialog, select the Safe Senders tab and click Add.
- Enter the full email address for the affected sender, and click OK twice.
