1.3. Legacy Mailbox Setup - Office 365 IMAP/SMTP

IMAP/SMTP settings can be used for Office 365 mailbox setup. However, we now recommend using HelpSpot's API integration with Office 365 as Microsoft will soon be disabling IMAP and SMTP basic authentication functionality.

Please note, before beginning that IMAP must be enabled for the Office 365 Mailbox you want to connect to HelpSpot. This can be done via the Exchange Online Remote Powershell (https://support.microsoft.com/en-us/kb/2416434) or via the web based exchange admin tools. Once your mailbox is setup properly:

1. Login to HelpSpot as an Administrator.
2. Navigate to Admin > Email Mailboxes
3. Enter your account information. The non-account specific information is as follows: 
   Hostname: outlook.office365.com 
   Account Type: IMAPS 
   Port: 993 
   Security Type: SSL no-validate
4. Test your mailbox settings to make sure that your inbound connection is successful
5. Next select Custom for the Outgoing Email SMTP Settings to use
6. The non-account specific connection information for SMTP is as follows: 
   SMTP Security Protocol: TLS 
   SMTP Host: smtp.office365.com
   SMTP Port: 587 
   Use SMTP Authentication: Yes
