Error: ‘access denied’ when attempting to run the Office 365 connector setup in the Exclaimer portal


When running the Office 365 Connector Setup wizard to create the transport rule and connectors required by Exclaimer Cloud, an access denied error is displayed and the wizard fails.

Reasons and solutions:

Possible reasons and associated solutions are summarised below:



The username and/or password has been typed incorrectly

Retype the username and/or password

The user specified is not a Global Administrator

The specified user must be a Global Administrator - you can create a new account, or use an existing Global Administrator account.

Your Office 365 plan does not support the use of transport rules.

Your Office 365 plan type does not support the use of transport rules (for example, you have a Small Business plan). Upgrade to a Business Essentials plan, as a minimum.

Multi-factor authentication is enabled for the specified user.

Multi-factor is only supported via the use of an app password to complete the setup.  This can be setup using the steps in the guide here
