All of my emails have been deleted from My inbox from the last three years ! 
my inbox won’t even hold five messages for a few days they just keep disappearing off my phone ...

I haven’t changed my settings in all the time I’ve had my email so not sure what’s happening?

I have Shaw web mail and they are still there but they’re disappearing off of my email system on my phone which I’ve never changed anything on my phone at all..

i’ve had my emails on my phone forever they just started disappearing all of them..
