Error "Call was rejected by callee" after process start in Orchestrator

Help Studio

Hi there,

For some time now the following error has occurred when I start a process in Orchestrator or when the same process is to be started via a trigger:

The property accessor Account for the UiPath.Mail.Activities.Business.OutlookApplicationCard-Object threw the following exception: An instance of the COM component with CLSID {0006F03A-0000-0000-C000-000000000046} could not be created from the IClassFactory due to the following error: 80010001 Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED)).

In Orchestrator\Jobs the state “Faulted” is displayed.

In Orchestrator\Logs it is displayed that the process started and finished a few milliseconds later:

After a few re-starts in Orchestrator the process runs successfully. The number of necessary re-starts varies.

Does anyone have an idea what the cause of the error is?
