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

Just a reminder - in my experience:  When it requests your login, you can simply exit the pop-up (X) and it will go away and the file will be stored as expected (OneDrive).  Check with Windows Explorer for date and time.  This is my experience - 100% of the time.   Therefore, I have not downgraded - I just live with it for now, hoping for a fix in the next release.

Certainly if you want to get rid of this annoying pop-up you could downgrade but that might reverse some security patches.

For me, it appears that if I exit one time, the pop-up does not return until a reboot.

Again: Win 10 Pro, Office 2016 (not 365).

Just a thought..

Windows 10 Pro x64

Office 365 v1707 (build 8326.2076 Click-to-Run)

The _vtc_rpc dialog issue also showed up after this update for Word, Excel and Powerpoint (I haven't opened the other programs yet but I'm assuming same problem).

Office Repair: Done

Cleared Credentials: Done

Doing the above did not work.

Below is what worked for me.

I put all my office documents into my OneDrive folders on my desktop so that it syncs up to OneDrive for me. I noticed the AUTO-SAVE switch on the upper left corner in from this latest update I assume. I have all on auto-update basically so I don't know if this was in previous updates.

When it's turned on, whenever you open a file for the first time from the OneDrive Folder (Didn't test from other non-OneDrive Folder since all my files are in OneDrive), it will initiate an auto-save to OneDrive and super annoyingly updates the Date Modified meta-data as well, it will also pop up the _VTC_RPC_

If you open the same file up again, the _VTC_RPC dialog doesn't show up again.

In the OneDrive App settings.

Disabling this made the _VTC_RPC problem go away.

However you will have to put up with a little annoyance which is the save dialog everytime you close a file even if you did no edits.

Hi,

It could be that multiple accounts was used to log in to Office. We suggest that you log out of Office and log in again. Keep in mind that your settings or preferences would revert back to the default state and that you may have to configure it again after signing in.

Update us on the results.

Hello Angel,

For us to isolate the issue about a pop-up that needs an account in opening a file, kindly respond to the questions below:

1. Is the issue specific to one file or with every Word file?
2. Have you checked if your Office application is updated?
3. Are you signed in to Office?
4. Have you associated your Microsoft account with Office?

We look forward to your response.

I will follow-up here since they did not, I am having the exact same problem. I will also let you know that this happens only on the first open of an existing word document. let me know how else I can help you get to the bottom of this. Is it a security concern?
