The RPC server is unavailable.(Exception from HRESULT: 0x800706BA)

Hi there. I was trying to run my workflow but the above mentioned error pop-up. Currently I’m running the workflow in Remote Server and it working fine for the first run but when looping for the second run it failed.

I had been trying on the workaround solution to put the delay activity and also killed the excel application before each scope but still facing the same error. Any other possible solution or workaround for this error.

Thank you.


Hey @tansey

Will you be able to do a quick check on the remote system after first run stop your bot and check manually in task manager is still excel.exe process is running in the background?

if so let me know and what Office version you are using like 2010,2016? or so?


Hi @aksh1yadav,

I’m currently using Office version 2016. Checked on the task manager, excel.exe process is not running in background.



Hi @tansey,

Can you find a solution?
I encountered the same problem as you.
