CPUU fails to connect to on-prem exchange 2016 after successful creation of temp profile

source: exchange 2010 | target: Onprem exchange 2016 | Microsoft Office 365 ProPlus - en-us | CPUU 5.8.3

  • upgraded CPUU from 5.8.1
  • every variation of permissions with no luck. (service account in the Target, service account in the Source, different service account for source and target, user's credentials prompted/pass thru)
  • reapplied permissions to mailboxes (target and source) and confirm access to mailboxes using autodiscover url from workstation
CPUU connects to source mbx retrieves all the settings, logs onto target mbx creates a temporary profile, fails a the last step of "Setting credentials for MAPILogon:"
using the command line -LeaveTemporaryProfile I can successfully open the temporary target profile 

Started logging on to profile 'CPUU_{1513216511651mkjmjm0b0000000000}'.

  • right, makes sense when I use the service accounts when running CPUU not so much when I prompt for user creds or use "logged on account".  so for service account, are there other permissions required on target exchange 2016 other then impersonate, full access, send as, receive as that would authorize the service account to sync and switch the mailbox but not allow access logon to the temp profile (target mailbox)?
