I was using this configuration
When I switch back to the Inbox and select a message, I then get the following error.
IMAPX68 NO Some messages could not be FETCHed (Failure)
other times I get the below but no body
IMAPX155 OK UID FETCH completed
IMAP.Behavior.FolderTreeBrowseMode = FolderTreeBrowseMode.Full
IMAP.Behavior.AutoPopulateFolderMessages = True
I just added this IMAP.Behavior.AutoDownloadBodyOnAccess = True
I view a few messages in the inbox, then changed folder and viewed messages from important. When I switch back to the Inbox and select a message, I then get the following error.
IMAPX68 NO Some messages could not be FETCHed (Failure)
other times I get the below but no body
IMAPX155 OK UID FETCH completed
