In my project BSU faced issues like , In Email while uploading the attachments its looks fine and sent the email to user once its done , when BSU trying to open the attachment in CASE its showing error like " unable to open the attachment .you lack the required permission"
FYI : its not protected file. the maximum length of the file name is 64 only, when its exceeding this value its shows error like above.
The same document when we rename to less characters its looks good.
