Using older versions of Outlook for Mac in business environments
Hi Joatheman,
Which Outlook 2016 for Mac version are you using?
May I know whether you have tried to check this issue via inserting a picture in Outlook 2016 for Mac?
However, inserting a picture requires that your message uses HTML formatting. To set HTML formatting, select Options > HTML.
In the body of your message, click where you want to add a picture.
On the Message tab, click Pictures.
Select the option you want to use for inserting pictures.
For more detailed information, please refer to the article under Insert a picture in Outlook
Best regards,
Shyamal
