MacBook Air keeps reloading old emails
I have replaced my old MacBook Pro with a MacBook Air OS Monterey. The apple specialist dealer installed all the old data onto the newer model for me.
The MacBook Air now keeps reloading all the old emails at random moments, today it was 15000+ reloaded after lunch when I just opened email to read a new message.
Any ideas what I can do about this or is it normal ?
Thanks
