Can you refer this post

Mail attachments empty or missing

Update: After I spoke with our IT department I learned that it has to do with my company’s IT policies. Apparently, Office 2016 allows companies to apply policy restrictions more specific and targeted. Restrictions, which under Office 2013 would have crippled the Outlook performance can now be applied taylored to a specific policy. I switched to the Exchange Server Activities, which seem to work for my purposes.

This type of Problem might occur , Hope this helps
