Error "Failed to install app" when installing Out of Office V2

Question

Why do I get an error Failed to install app: Error creating requirements//the task failed because of an error: Validation failed: Key: agent_ooo when installing the OOO (Out of office) V2 app? 

Answer

If you installed the previous version of the Out of Office app, the app creates a user field called Agent Out? which corresponds with the ​agent_ooo​ tag. To successfully install the Out of the Office V2 app, delete the Agent Out? field by following the steps below.

1. Go to Admin.
2. Under Manage > click User Fields.
3. Look for the Agent Out? field then Delete.
