Scenario
When you run the Microsoft 365 Connector Setup to create transport rules and connectors required by Exclaimer Cloud, you get an access denied error.
Reasons and resolutions
Some of the possible reasons and associated solutions are summarized below:
|
|
Solution |
|
|---|---|---|
| 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 Microsoft 365 plan does not support the use of transport rules. |
Your Microsoft 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. See this article from Microsoft on how to Create an app password for Microsoft 365. |
