MS Word Documents migrated shown Blocked Attachment inside the content.
This is due to the corrupted attachment references created by the 3rd party add-on to the domino. The core issue is that, since the 3rd party tool was not saving attachments correctly in Notes, there is no consistent or reliable way for a tool to extract and migrate them.
Re-saving the document attachments might fix the data, and perform the migration after that.
Save the document attachments locally and re-attach to the migrated MS Word Documents
