I’m sure it’s a simple setting that I am missing, but I would really appreciate if somebody could help me out and walk me through thesteps. If this is not the correct community, please don’t just delete this post. Please let me know where to post it at and I will Make the change. I should ask is it even possible using Excel 2019 to have it use what I think is the newest version of outlook as the default email program on Windows 10?
I would take a look at your default apps. Check the ‘mail’ app and make sure it’s set to outlook and not the builtin mail app. If it isn’t outlook, set it to outlook and restart your computer then try sending from excel again.
