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!
