I have a document library in SharePoint Online. The end user submits about 30 documents to add metadata and to be approved. One column of the metadata is used to group the documents together. If the documents are approved no email is necessary. If they are rejected the library curator selects all the documents in the group and through bulk editing fills in a multi-lined column marked Deficiency with the reason why of the rejection, then changes another column to Rejected to initiate the workflow.
This sends out as many emails as there are document in that grouping. Is there any way to send out just one email when the grouping set is rejected?
