How do I grant the Microsoft 365 permissions for my organisation to use MailMerge365
What is "admin consent" — and why does it matter?
MailMerge365 requires permissions that only an administrator can grant, e.g. sending as a shared mailbox (which is a feature of MailMerge365 even if you don't use it personally). You can grant tenant-wide admin consent to enable the application to access the requested permissions on behalf of the entire organization. This ensures that ordinary users in the tenant are no longer individually prompted.
Simplest way: Use the "direct URL"
The fastest way to grant the permissions as an administrator is this link:
https://login.microsoftonline.com/common/adminconsent?client_id=d87015f3-71a7-42c3-80cb-5e0f636703ae
You will be prompted to log in as a user with administrative rights in the Microsoft 365 tenant (the entity that holds all the information and mailboxes for your organisation).
Alternative approach: Use the admin-center
Through the admin center:
- Go to Enterprise applications →
- All applications (or App registrations → All applications)
- Locate "MailMerge365"
- Review the permissions, and
- click Grant admin consent.
