If your add-in(s) are disabled after a PC reboot each day, your IT can change a Windows setting to prevent this from occurring.
The issue occurs because the Load Behaviour of the Add-in changes in the Office application (there can be several factors for this including starting slowly)
There are a number of Load Behaviour states that can occur and they get written to a registry value for the Add-in. In order to restore the default behaviour of loading at startup the registry value needs to be changed to a value of 3.
The possible Load Behaviour values are list in the following link but anything other than 3 essentially means the Evolve add-in won’t be displayed.
There are 4 registry keys where the “LoadBehavior” value (note the American spelling!) can be set for the Evolve Add-ins (2 for Outlook and 2 for Word).
In each case a DWORD value is set with the name “LoadBehavior” and the value of 3.
