Android Email Exchange Issue

We recently had to restore from a server backup. For the most part everything restored fine with the exception of one company LG phone that does connect to the Exchange server with the correct credentials. It however will not display the email. It can send email, gives no connection errors but no visible email in the native email app. I used another Exchange email credentials and it did pull all of those email where they are visible. I get the same results from other apps. The user also is able to sync and view the email on the laptop without any issues. Anyone ever experience this?

Delete the profile off the phone and recreate it.  Once it syncs all should be well.

Scott thank you for the reply. If you mean just delete that exchange email account, i did do that several times and it continues to do the exact same thing when I add the account again.

Try the problem account on another device...not a laptop.  This will narrow it down to something on the LG or with the user's account.

I know you used another account on this device and it worked, but there could be some junk being left behind causing the issue.

I did the restore on the entire server image that included everything with the OS. I also tried her email on another mobile device and had the exact same outcome. It has to be something in Exchange, I just don't know what or where to proceed. Thank you for the replies!

Don't know if this will fix anything but give it a try.

New-MailboxRepairRequest -Mailbox ayla -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview -Archive

If the mailbox repair doesn't work, I'd backup all emails to a PST, delete the mailbox, re-create it, import the PST and see if that works.

Ill give it a try later today. Really appreciate your time!
Scott CSenior EngineerCommented:
Sure thing.  If the above doesn't work, we can try enabling ActiveSyncMailboxLogging.

This will show any and all activesync traffic.  We'll be able to see what is and what isn't syncing.

Open Exchange management shell on any Exchange server. Run cmd below,
Set-CASMailbox aliasofUser -ActiveSyncDebugLogging:$true
To retrieve logs.
Get-ActiveSyncDeviceStatistics -Mailbox alias -GetMailboxLog:$true -NotificationEmailAddress

Set-CASMailbox aliasofUser -ActiveSyncDebugLogging:$false
