Office files opening as Read-Only

What is the problem you are having with rclone?

Office files opening in read-only mode.
(Using Rlcone / WinFSP / NSSM)

I can write to the network location, it allows me to create new files in there. But for some reason when opening files that already exist they’re opening as read-only.

Checked Excel trusted location and added the drive to the trusted locations with trusted network locations also checked. Same issue.

Run the command 'rclone version' and share the full output of the command.

rclone v1.70.3

  • os/version: Microsoft Windows 11 Pro 24H2 24H2 (64 bit)
  • os/kernel: 10.0.26100.4652 (x86_64)
  • os/type: windows
  • os/arch: amd64
  • go/version: go1.24.4
  • go/linking: static
  • go/tags: cmount

Which cloud storage system are you using? (eg Google Drive)

One Drive / Sharepoint

The command you were trying to run (eg rclone copy /tmp remote:tmp)

NSSM Arugment - mount Prior_Construction: X: --vfs-cache-mode=full --file-perms 0777 --dir-perms 0777 --network-mode --config "C:\Users\Luke\AppData\Roaming\rclone\rclone.conf

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.

[Prior_Construction]
type = onedrive
token = XXX
drive_id = XXX
drive_type = documentLibrary
link_scope = organization

A log from the command that you were trying to run with the -vv flag

Tried to add the --vv flag to my NSSM arugment but the service wouldn't start.

welcome to the forum,

for testing, run rclone on the command line, without NSSM.


the flag is -vv
if you had run rclone on the command line, would have seen Fatal error: unknown flag: --vv

need to post a debug log of the error, something like
--log-level=DEBUG --log-file=c:\path\to\rclone.log

i did a quick test, was not able to reproduce your issue.
i was able to open .xlsx file stored on onedrive, then edit and save

[sodl]
type = onedrive
token = XXX
drive_id = XXX
drive_type = documentLibrary
link_scope = organization
rclone mount remote: x:  --vfs-cache-mode=full --file-perms=0777 --dir-perms=0777 --network-mode -vv 

relevant log entries

DEBUG : zork/btech.xlsx: >Open: fd=zork/btech.xlsx (rw), err=<nil>

did another quick test, with less flags, and again, no issues, was able to open,edit,save a .xlsx file stored in onedrive

rclone mount remote: x:  --vfs-cache-mode=full --cache-dir=d:\rclone\cache\sodl -vv 

Any “clever“ anti virus software installed other than MS Defender? If so try to disable it at least temporarily completely.

So I’ve tried just using the Rclone mount without the NSSM and it works fine. So must be NSSM causing an issue along on the line. thats fine I can sort it from there.

I’m rather new to using Rclone, so we started to use this vs. Cloud drive mapper due to cost saving. We have some shared excels that multiple people work on at the same time. When trying to access via Cloud drive mapper I can see the multiple people working in the sheet but on Rclone it doesn’t tell me that. Before I start messing around I just wanted to check if there was something else I needed to do to replicate shared documents working or is it a limitation?

for rclone mount, i use windows built-in task scheduler, has a nice GUI and command line.
important to specify the windows username that the task will run under and if the task should be run with admin privileges.


what is that, what is the website?


test it for yourself, see what happens.

rclone mount does not provide any functionality for multiple users (mount points) to work on the same file. Whoever saves the file last this is what will be stored in the cloud… You either use specialised collaboration tools or change the way how your users work.

Perfect Thanks all
