I lost my incoming emails on iCloud and btinternet
My husband has suddenly lost his incoming emails both iCloud and btinternet for all of 2021 and the first 6 weeks of 2022. He uses the Apple Mail App on his iMac Monterey, 8th generation iPad and 1st generation iPhone SE. They are not on the app or on the web. He has no backup. BT said there was no problem with their system and Apple said it must be a fault at BT’s end. Is there any chance of these emails being found?
