Email Services/Office 365/Migration Notes

• Outlook for Windows users not in cached mode do not seem to automatically reconnect. They also report slower performance when compared to on-Premises Exchange
• Some Thunderbird users had to delete and recreate their profile. Simply changing the server name and login settings does not always re-establish connectivity
• Most Android users had to delete and recreate their Activesync connection for their Mobile device to function
• Users with subdomain email addresses as their default email address recieve undeliverables when sending to external recipients. The workaround is to configure their mail client to send through smtp.anl.gov instead of smtp.office365.com. A ticket has been opened with Microsoft to determine the cause of this problem.
