Frequently Asked Questions
Common questions about Sendelva – Email Delivery for Microsoft 365
No. Sendelva talks to Microsoft Graph over HTTPS with an app-only token. There is no SMTP connection and no mailbox password.
The Microsoft Graph application permission Mail.Send, with admin consent. Without consent, Microsoft issues a token but refuses every send, which is the most common setup problem. Mail.Send as an application permission can send as any mailbox in your tenant. To limit the app to the one mailbox you use, add an Exchange application access policy. Microsoft documents this under "Limiting application permissions to specific Exchange Online mailboxes".
With fallback on (the default), the message is handed back to WordPress's own mailer and the send log notes that it was. With fallback off, the send fails and WordPress fires wp_mail_failed.
Microsoft Graph sends as the configured sender mailbox. A From header added by another plugin can't change that. Use Reply-To to route replies somewhere else.
Yes. Anything that sends with wp_mail() goes through Sendelva, and HTML emails stay HTML.
Attachments can total up to 3 MB, the limit of Microsoft Graph's sendMail request. Larger messages fail with a clear error (and fall back to the default mailer if fallback is on).
Its settings (including the client secret, unless you use the wp-config.php constants), a cached access token, and a log of the last 20 messages with each recipient, subject and result. Uninstalling the plugin deletes all of it, on every site of a multisite network.
Sendelva is Graph Mailer under a new name. Install and activate Sendelva: the first time it runs it copies Graph Mailer's settings and send log, and GRAPH_MAILER_* constants in wp-config.php keep working. Then deactivate and delete Graph Mailer. While it's still active, Sendelva shows a link to deactivate it.
No. It makes no requests of its own except to Microsoft's sign-in and Graph services, and only once it's configured. See "External services" below.
