We are sorry about this problem with editing attachments and error messages about other programs making use of a file. Thank you for looking to the Quicken Community for assistance.
Where is the attachment file being stored? Is it located in a cloud-based storage application, such as OneDrive? If so, that could be a potential cause for a message such as this. Also, where is your current active data file located? You can check this by navigating to File > Show this file on my computer… in the upper menu at the top of the screen. Make sure that your data file is located on the computer and not an external drive or cloud-based storage service, as these locations can cause erratic behavior and even data damage.
I look forward to your response.
