Consider the following scenario:
- You use Microsoft Outlook online mode to access a Microsoft Exchange Server 2010 mailbox.
- You have an additional POP3 account or an additional Internet Mail Access Protocol (IMAP) account in the same Outlook profile.
- You use the POP3 or the IMAP account to send an email message that contains an attachment.
This issue occurs because Exchange Information store returns MAPI properties that Outlook cannot handle. Therefore, Outlook cannot successfully submit the message and returns error code 0x800CCC13.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
