#3640 - Unable to manage add-in from user mailbox
I have rights to a user's mailbox, which I've opened. I don't see the option to manage add-ins from their account. Is this an option that needs to be enabled somewhere in Exchange? ![outlookoptions.png](https://www.sugaroutfitters.com/assets/img/support/grinmark-outlook-365-addin-for-sugarcrm/42ebcf56715b2f5ea34f34d70dc699e9/outlookoptions.png "outlookoptions.png")

Hi Killian,
The user must have missing permissions to install add-ins.
Here is the link to Microsoft docs: https://technet.microsoft.com/en-us/library/jj943754(v=exchg.150).aspx
It states that
_Assign users the permissions required to install and manage add-ins for their own use Use the EAC to assign permissions to users You can use the EAC to assign users the permissions required to view and modify custom add-ins for their own use. For detailed information about how to do this, see Manage role groups. _
