My company iManage LLC has an addin component in Outlook.

If you got the updated version and its still freezing upon sending pdf as attachment, then you may try the further steps. You may check if you have got the latest patch of Acrobat Reader DC installed or not? Open Acrobat>Help>Check for update Or refer to DC Release Notes - Release Notes for Acrobat DC Products Have you experienced this behavior of Acrobat while sending only a specific pdf as attachment or it happens every time you share the file?

When ever a user presses the mail button ( the little envelop ) and selects the default mail application, which is Microsoft outlook, it causes outlook to freeze until all Acrobat DC instances are closed.
