Allow Multiple Accounts vs WPO365 | MICROSOFT 365 GRAPH MAILER

Allow multiple user accounts to be created, registered, and updated having the same email address. By default, WordPress only allows a specific email address to be used for a single user account. This plugin removes that restriction. The plugin’s settings page (accessed via Users -> Multiple Accounts or via the Settings link next to the plugin on the Manage Plugins page) provides the ability to allow only certain email addresses the ability to have multiple accounts (such as if you only want admins to have that ability; by default all email addresses can be used more than once). You may also specify a limit to the number of accounts an email address can have (by default there is no limit). The settings page also provides a table listing all user accounts that share email addresses (see screenshot). Compatible with Multisite and BuddyPress as well. Links: Plugin Homepage | Plugin Directory Page | Author Homepage Template Tags The plugin provides three optional template tags for use in your theme templates. Functions Returns a count of the number of users associated with the given email. Returns the users associated with the given email. Returns a boolean indicating if the given email is associated with more than one user account. Arguments $email (string) An email address. Filters The plugin exposes three filters for hooking. Typically, customizations utilizing these hooks would be put into your active theme’s functions.php file, or used by another plugin. c2c_count_multiple_accounts (filter) The ‘c2c_count_multiple_accounts’ hook allows you to use an alternative approach to safely invoke c2c_count_multiple_accounts() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. Arguments: same as for c2c_count_multiple_accounts() Example: Instead of: Do: c2c_get_users_by_email (filter) The ‘c2c_get_users_by_email’ hook allows you to use an alternative approach to safely invoke c2c_get_users_by_email() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. Arguments: same as for c2c_get_users_by_email() Example: Instead of: Do: c2c_has_multiple_accounts (filter) The ‘c2c_has_multiple_accounts’ hook allows you to use an alternative approach to safely invoke c2c_has_multiple_accounts() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.

WPO365 | MS GRAPH MAILER provides you with a modern, reliable and efficient way to send WordPress transactional emails from one of your Microsoft 365 / Exchange Online / Mail enabled accounts. The plugin re-configures your WordPress website to send emails using the Microsoft Graph API instead of – for example – SMTP. Sending WordPress emails using the Microsoft Graph API has become the only available alternative after Microsoft has disabled basic authentication (username and password) over the SMTP protocol. DELIVERY Send WordPress transactional emails from one of your Microsoft 365 Exchange Online / Mail enabled accounts using Microsoft Graph instead of – for example – SMTP. Choose between delegated (send mail as a user) and application-level (send mail as any user) type permissions. Or: Select either a Microsoft 365 account or a personal Microsoft account, like Hotmail.com or Outlook.com, to send WordPress emails. Or: Configure RBAC for Exchange Online and authorize as an application but with a limited scope e.g. one specific mailbox. SEND AS HTML Send emails formatted as HTML. SAVE TO SENT ITEMS Emails sent will be saved in the account’s mailbox in the Sent Items folder, further helping to track (successful) mail delivery. ATTACHMENTS Send files from your WordPress website as attachments. WPO365 INSIGHTS See what matters, when it happens Track key WPO365 events like sent emails with WPO365 Insights more CONFIGURATION / TEST EMAIL DELIVERY Easy configuration with detailed step-by-step Getting started guide and video. Send test email to recipients incl. CC, BCC and attachment. ADD FUNCTIONALITY WITH PREMIUM EXTENSIONS The following features can be unlocked with the WPO365 | MAIL extension. WPO365 INSIGHTS Get WPO35 Alerts in your inbox when email delivery is failing more Auto-Retry Log every email sent from your WordPress website, review errors and (automatically) try to send unsuccessfully sent mails again. LARGE ATTACHMENTS Add support to send WordPress emails with attachments larger than 3 MB using Microsoft Graph. SEND FROM ALIAS Send emails from an alias address (but submit to Microsoft Graph as the authorized user). SEND AS / SEND ON BEHALF OF Send email as / on behalf of another user or distribution list. SHARED MAILBOX Send email from Microsoft 365 Shared Mailbox. STAGING MODE Mail Staging Mode is useful for debugging and staging environments. WordPress emails will be logged and saved in the database instead of being sent. DYNAMIC SEND-FROM Allow forms to override “From” address e.g allow Contact Form 7 to dynamically configure the account used to send the email from (requires application-level Mail.Send permissions). MAIL THROTTLE Throttle the number of emails sent from your website per minute. WP-CONFIG FOR AAD SECRETS Further improve overall security by choosing to store Azure Active Directory secrets in your WordPress WP-Config.php (on disk) and have those secrets removed from the database. SEND AS BCC Send emails as BCC instead and prevent reply-to-all mail pollution. REPLY-TO Configure a default reply-to mail address if this should differ from the account’s mail address that is used to send WordPress transactional emails from.
