MS Outlook is a widely used email application, and there is a reason for that. Users can easily configure other email accounts like IMAP, POP, Office 365, or Exchange with MS Outlook and access all their emails/messages in one place. But, having many folders and messages with attachments often makes Outlook slow, especially when you configure many IMAP accounts with Outlook.
Many users often receive an error “Outlook cannot synchronize subscribed folders” when connecting IMAP emails with Outlook. Though it is not for every email account, the error notification says 11 of 14 tasks have been completed successfully with reported error 0x800CCC0E.
Reasons for This Error
This error occurs because Outlook downloads all the messages with attachments when you connect an IMAP email account with it. Also, with an IMAP email account, only headers are synchronized to represent crucial information, and the email’s attachments are only downloaded when you open/view a message, or you have set Outlook to download all messages.
When you receive this error, it means Outlook is not set up to recognize that the server requires an Advanced IMAP configuration parameter to read from the folder structure properly. So, here, we will talk about the methods that can be used to resolve this error.
