What do I do if Outlook hangs when DeploymentPro configures a new Outlook profile?
The most common cause of this issue is an unresponsive ClickToRunSvc service.
To resolve it, check to see if OfficeClickToRun.exe is running during the hang. If it is, stop the service by the following these steps:
Use any of these methods:
OfficeClickToRun.exe hosts the ClickToRunSvc service, which hosts a number of ALPC endpoints. One of those ALPC ports is "\RPC Control\C2RClientAPI_Server_System16". Outlook and Skype for Business attempt to connect to "\RPC Control\C2RClientAPI_Server_System16" during startup and initialization. An unresponsive ClickToRunSvc service will cause an inability to communicate with the above-mentioned ALPC port which, in turn, will cause Outlook and Skype for Business to hang.
