I know it's a huge pain in the neck but it's great to hear that so many people have the same problem. Except for one person (who I would like to have test again) it seems that the problem is just with Exchange servers. Which means Apple should get it fixed pretty quickly. I have an open support issue with Apple. It would probably help if everyone contacts Apple - the more reports they get the faster they'll realize it's a big problem.
The solution is easy, delete your Exchange account then add it again. I did this and the problem is solved for me.
It's actually under Setting -> Mail -> Notifications -> (your account)
I found another option there called "Show on lock screen" which has been disabled. Enabling it fixes the problem - no need to disable "Show in History"
Fixed in iOS 11.2.5 Beta 1
Finally! I just installed the public beta and yes, confirmed fixed. Whew...
I'm having this issue with Exchange, Gmail, and Yahoo ... normally I use Outlook as my mail client for all three, but I verified that same problem exists with the native iOS Mail and Gmail apps.
You can report this bug here:
I think I might have a solution - Settings->Mail->(your account)->turn off "Show in History"
I was having the same problem, but only with my Exchange (work) account. The suggested resolution of unchecking show in history resolved the problem.
I was able to stop by the Apple store and the techs there did not have an answer either. They believe it is a bug. I did find a slight work around that after it unlocks if I swipe up from the middle of the screen the email notifications are listed there. Not perfect but maybe they fix the issue in 11.2 otherwise this is going to get annoying real fast.
I posted the issue on Apple Bug Reporting tool and uploaded a video of the issue:
I have two email accounts that use the iOS Mail Client, one is iCloud the other is a work Microsoft Exchange Server. The issue is that when the phone is locked it will display notifications, for example an iMessage, a iCloud email, and an exchange server email. I will look at the phone to unlock and the exchange email notifications will disappear while the two other notifications will stay. This happens everything time no matter how many exchange server emails I have, they all disappear from the lock screen when the phone unlocks with FaceID and all other notifications stay. Now once I have completely unlocked the phone and am on the home screen I can swipe down the notification center and the emails are still listed there. This appears the only App that has this behavior. The notifications settings are exactly the same on iMessage and Mail app and the iCloud and Exchange Server email account have exactly the same notifications settings. I have attached a video showing exactly what is happening.
I posted a link to this thread for them to see other are having the same issue.
Same issue for me. Didn’t set up the Exchange account on my X until Monday, but it’s had the glitch ever since. Turning off “Show in History” fixes the lock screen problem, but now I can’t see emails in my history. I’m constantly going back and forth between the mail app to make sure I haven’t missed an email. Thanks for posting—glad to know I’m not the only one.
For me the notifications are driven from senders I have on my VIP list, so they are contacts that span several email types (gmail, yahoo, exchange). I was able to turn off the "show in history" here: Settings -> Notifications -> Mail -> VIP -> Turn off "Show in History".
Odd thing for me is this (initially) worked as I think it should have, and recently changed.
I’m using mail app, with exchange gmail account. I also have iCloud mail and it doesn’t happen for this account.
Glad I found this thread - hope it is a bug as its annoying.
Thanks

After promising to call me back a couple of times last week I stopped hearing from my support rep. I had also filed a Radar bug report. And engineer requested more info, then the bug report was closed as a duplicate.
So they clearly know that this is a bug. Hopefully they'll get it fixed soon. I wonder if it's happening to EVER Exchange account or just some?
And we're back to full on broken in beta 3. All emails are again disappearing from the lock screen after I updated to beta 3 this morning. Dammit - should have stayed on beta 1 I guess! Apple, get your $h!t together...
