Sending emails with Office 365
If you need to use an Office 365 account in your email sending settings, configuration changes are required in multiple areas, as Microsoft no longer allows the use of the SMTP protocol without authorization within the Azure tenant.
1. Set the O365 mailbox as both "Email Adress" and "User" > In the "SMTP Server" field, enter:
smtp.office365.com > Complete the configuration by entering the mailbox password in the corresponding field.
-
Port: 587
-
Authentication: Yes
-
Use SSL: No
-
Use TLS: Yes
2. As with the Azure log registration procedure, the application must be authorised at the Tenant level and the required Microsoft Graph permissions must be obtained for "Mail.send".
3. In Setting > Cloud > Azure click the [Edit] button at the bottom.
The configuration window will open:
Enter the three parameters specified in the Azure Tenant, and select the "Use Mail Account" option in the corresponding tenant. The sender mailbox must be part of the Azure AD (enter the ID).
ATTENTION:
After the configuration is completed, BlogService must be restarted to apply the new parameters.
