Need help I use an iphone 6s for emails but for some reason the BT Server is deleting my emails after approx 10days. for example the earliest inbox email is the 25/07/18 i have at this time exactly 11 emails in my in box. sent items are all there no problem. I thought it was a phone problem so i contacted Vodaphone they said there is no archive on my phone. Next we checked via Google by BT account and the emails are not there. Ive had my phone checked by our IT group and there is nothing wrong with my phone.
I also have an I pad the in box has all my emails 100's the i pad is not affected by my phome issue.
can anyone help with this when i called BT im told it cant be a BT problem. but it is.
