Hello,

Symptom:

1 user syncs more than 1 week of mail they receive the error "Cannot Get Mail - The connection to the server failed."

We have tried all of the following:

Removed/re-added accounts on the device

Added the account on several other IPhones/IPads, different iOS versions, all receive this error

Removed the devices from OWA, ECP

Deleted the AD account and recreated and created a new mailbox, imported PST

New-MailboxRepairRequest -Mailbox user -CorruptionType ProvisionedFolder, SearchFolder, AggregateCounts, Folderview - completed with no errors

IIS logs all show 200 on authentication

User is not part of any protected groups and has permissions set to be inherited.

Had user move all mail older than 2014 to folders, in hopes to shrink main inbox

Get-CASMailbox -Identity user | ft Name, ActiveSyncEnabled - returns "True"

Manually removed CN=ExchangeActiveSyncDevices from ADSI edit

Works fine syncing on my Android device

I'm out of ideas here guys! Please help!
