I use Mail on my iPad mini iOS 9.2 with 3 different email addresses coming in, one of which is Gmail set up as IMAP to download onto my iPad and my iPhone 6. I have iCloud set to backup everything including Mail. Today, for whatever reason, all my emails from my Gmail account just disappeared as I opened Mail, and they are gone from my Gmail webmail online too. Gmail says they can't help. I am hoping that I might be able to recover them using my iCloud backup, but don't know how to do it. Please can anyone help? Thank you.
This issue is most likely something to do with Gmail and it's syncing. Check Gmail.com to see if your mail is still there.
If it is, try deleting your Gmail account from your iPad (Tap Settings > Mail, Contacts, Calendars > (your Gmail account) and press "Delete Account". Then add the account back by tapping Settings > Mail, Contacts, Calendars > New Account. Select Gmail and input your credentials. This should bring back your mail.
If you need to restore from an iCloud backup because the mail on your phone was archived locally and not synced to Gmail, restore from an iCloud backup as detailed in Apple's Support article:
- Erase your iPad by tapping Settings > General > Reset All Content and Settings
- After your iPad has been erased and your device has presented the greeting screen, follow the steps. Join a Wifi network, and follow the next steps.
- Tap "Restore from iCloud Backup". Sign into iCloud and choose the backup you want to restore to your device.
- Continue to follow the steps until you have restored your iPad and your locally archived mail should be where it was put.
