Hello, It seems that including IMAP credentials to use an Office 365 shared mailbox as own email server do not work. The same details work on other third-party applications that we use. The check details button even validates that the details are correct but they cannot be saved as the email address form on the page has a constraint that does not see it as a valid email address. Example Username: firstname.lastname@example.org\SharedMailboxName Password: myuser password Ideally, it would be great if the form validation could be changed to allow a username in this format as it passes connection tests. What would also be needed in order to use our own SMTP server to send would be the ability to supply a different username and password for the SMTP server. Example username: email@example.com password: mypassword I have come across this same issue before with other third party apps but they have been solved quickly so I have every confidence that servicecamp will make the changes required also. It's a quick and easy change request that will help out all other Office 365 and Exchange users with shared mailboxes ( Every Corporate client will most likely use these ). The ability to authenticate this way is already there. Its just being restricted by form validation and the lack of an input field to specify a different username and password for SMTP.
