We have our own on premise exchange 2016 server so we tried changing the max file size on our exchange server to 35 mb but still no luck.

These sizes are under our allowed size limits for internal and external mail.
That action opens the mail share sheet. Quick tip on ios mail attachment. Just like with any other attachment you compose a new mail attach the files and send.
