My office just upgraded from an older version of Outlook and an in house Exchange server to Office 365. I reinstalled the Citrix Files plugin for Outlook and now it no longer converts an attachment automatically when I drag and drop a file into an email. It works if go to Insert then Attach File in Outlook or Attach Files using the Citrix Files plugin, but not when I drag and drop. It will also convert manually with a drag and dropped file. Just not automatically. Please help.
