OWACurrent en:Single User Deployment
Please note that this option is only suitable for users who use Outlook On The Web through a single-user license.
If possible, we highly recommend you to leave the deployment of the Add-in to an experienced administrator. Among other things, you won't be able to benefit from these features:
- Automatic updates when the administrator deploys a new Add-in version
- Better technical support due to more advanced logging capabilities
For single user deployment instructions, please refer to the official Microsoft Documentation on how to use Add-ins in Outlook On The Web.
