Yes, Attachment Manager does support detaching or re-attaching attachments for all emails of the Outlook folder in one click. Go to Attachment Manager > Advanced and select ‘Detach All’ or ‘Re-attach All’ options.
As soon as you click on either of the two options all the email would be processed in a batch, if you click on ‘Detach All’, Attachment Manager would be detaching all the attachment from the emails, whereas if you click on ‘Re-attach All’, it would be re-attaching all the attachments in the email.
