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

I just upgraded to the new Monthly Channel build:

Version 1708 (Build 8431.2070 Click-to-Run)

In this build Autosave has been greyed out and set to off, so the issue no longer occurs. So while I don't get the pop up anymore, the autosave functionality has been removed from the current build. So there is some progress!

I ran into the issue again this morning when I tried to close a file, in Word, that had been created some time ago. It did not occur when I closed another file that I had looked at last night and that had been created more recently. I am trying to explore the previously suggested idea that this glitch affects files that were created before one of the recent updates. In any case, the workaround, x-ing out the dialogue box, seemed to work just fine. It is only frustrating that Microsoft does not seem to have any sense of urgency with these kinds of frustrations.

Hi David,

I'm joining this thread today having just experienced this issue with the 1707 build of Office365. My setup and experience is exactly like VesoMitev in this thread, though I will not I had no issue with Word, only Excel.

Just letting Microsoft know it's a bug and we need a real patch. Thanks.

Office 365 subscription. Same here, with "_vti_rpc pop-up" tried everything suggested:

• Office updated - check;
• Cleared credentials - check;
• Reinstalled OneDrive - check;
• Only 1 user account - check;
• Linked with Microsoft - check
• no results achieved so far :(

Happens both with Word & Excel 2016 as part of O365.
