email attachments keep sending as wimail.dat
I’m using outlook on my macbook air 2019, when sending attachments to other mac or windows users they arrive as winmail.dat
This never happened when using outlook on my older macbook air.
My email account is using microsoft exchange and both my iphone pro max and macbook air 2019 sync emails.
How do I stop the above happening and just simply, if say I send a pdf attachment then it should arrive as one, thanks, Chris.
