Can EP 5 send mail through a hosted Office 365 mail server?
Currently the email option in EP5 only supports basic authentication and defaults to port 25 and does not allow you to enable TLS or SSL encryption.
Some mail servers such as smtp.office365.com require a different port and for this encryption be enabled. EP5 cannot be used with this type of mail server at this time because we cannot change our ports and we do not support encryption.
A feature request to add these options to the EP5 mail settings for scan to email and emailed reports, similar to the advanced options in Outlook has been submitted in order to potentially add this functionality at a later date. As EP5 is designed today, this functionality is not available and this is not a confirmation that this feature is guaranteed to be added in a future release.
