    Rodawing   I have found the issue.  It is caused by and Adobe Acrobat Pro add-in.  

    The issue is with the Adobe Document Cloud for Microsoft Outlook – Acrobat Add-in.

    If the Add-in is enabled and Edge is set as the default PDF viewer you cannot send a delayed delivery message. (it will immediately change to a draft and stay in the Outbox) Delayed delivery will also not work if you have Acrobat Reader DC set as the default PDF viewer and the Adobe Document Cloud for Microsoft Outlook – Acrobat Add-in enabled.   If you disable this Add-in and have Edge set as the default PDF viewer, delayed delivery works fine.
