Outlook activity issue - call rejected by callee

Hi everyone,

I have a robot that’s been running in production for over a year without issues. However, we recently started encountering errors before the process even begins.
For email functionality, I check if Outlook is available, then use the ‘Open Application’ (Outlook) activity, followed by the ‘Send Outlook Mail Message’ activity. Could you please help analyze and resolve this issue?

Error message : Property accessor ‘Account’ on object ‘UiPath.Mail.Activities.Business.OutlookApolicationCard’ threw the following exception: ’ Creating an instance of the COM component with CLSID {0006F03A-0000-0000-C000-000000000046} from the IClassFactory failed due to the following error : 80010001 Call rejected by callee. (Exception from HRESULT : 0x8001001 (RPC_E_CALL_REJECTED))

Can you try the below points once.

  1. Upgrade Mail Packages
  2. Setup the outlook again with Repair or Reinstall options.

Welcome to the community

As per error looks like the license is expired or outlook has been upgraded

If upgraded then try to get latest version of mail packages…if outlook is expired or programmatic access is revoked then make changes accordingly

Cheers
