Tell us the account you want to use to open _vti_rpc.

I had the same problem I was able to fix the problem by clicking on the one drive icon in task manager, then go to the settings cog, then choose the office tab and uncheck the use office 2016 to sync office files I open. then click ok.

Hope this helps :)

I haven't figure out a pattern =(  ... I use office 2016 and Windows 10 and have a OneDrive account I log into on two different computers and one with Windows 7 and Office 2013.  I don't think I've ever had the issue on the Windows 7/2013 machine.  When/If it happens again I'll post all of the details.  Hopefully the update fixed the issues.

Thanks everyone!

Now, after the office applications installed the latest vetsion: 1710 (build 8613:1000) in fast ring and used applications for a whole week, I found this issue hasn’t occured any more.

The Windows version is currently using the insider version, 16296 in slow ring, but OneDrive has updated into the 2017 version. I think it may solve the problem.

I also get it on PowerPoint.

With Word and Excel, I can "X" out of the dialog and move on.

With PowerPoint, it just freezes and I have to kill the whole process in Task Manager :(:(:(

I'm on build 1607 and still getting this problem.  It only affects Word and Excel.

Its been happening now for at least 5-6 weeks.
