OneDrive | Synchronize–Issues

Sync Client Reset

Do you have issues with the synchronization of OneDrive files?
in Windows Explorer you see files, that will never end to synchronize?

So there are more than one possibilities to fix the it. There is an easy part to fix that with an OneDrive Reset

I have had some issues on a Windows device. During the start Sync is done, but during normal operations no sync is done with this tenant, (I have synced files with two different tenants on this device and the other tenant works well. I have to fix it.

Looking inside that not normal syncing tenant I found such:




OneDrive for Business



SharePoint doc libraries






Because I use ‘files on demand’ not all of the above files will be synced. Most of the files are Cloud Only.  But the structure, folder names and filenames must be synced. So some information will be in a cache, and this should be cleaned too.

Call the Execute app

So you have to enter “RUN” in the search Windows on the left corner and Press Enter. Then you should copy the next line into the Run window:

%localappdata%\Microsoft\OneDrive\onedrive.exe /reset

Execute an Order

First, the Next Generation Sync client (OneDrive.exe) will be stopped. After that, a REST will be executed. All different Sources (OneDrive for Business, OneDrive Personal and all different synchronized document libraries are reconciled. This may take a few minutes. If nothing happened, you should Restart your OneDrive Client manually:


But if you have such an amount of data, it takes a while. And of course, it depends of Internet bandwidth and Speed of your device.

Give your device a chance….

OneDrive | Synchronisations-Probleme?

Sync Client Reset

Ihr PC zeigt bei OneDrive Synchronisationsprobleme an?

Im Explorer werden bestimmte Dateien angezeigt, die ununterbrochen synchronisiert werden?

Dafür gibt es mehrere Möglichkeiten, das Problem anzugehen. Eine einfache Art ist es , einfach ein Reset auf den Synchronisations-Client auszuführen.

Ich hatte bei einem Rechner seit ein paar Tagen Probleme. So wurde die Synchronisation nur bei Start von Windows ausgeführt. (allerdings nur bei einem Tenant, denn die Synchronisation bei dem zweiten Tenant funktionierte immer. Das wurde lästig.


Hier einmal das Mengengerüst




OneDrive for Business



Dokument Bibliotheken






Weil ich ‘Files on Demand’ einsetze, werden nicht alle Dateien synchronisiert. Aber zumindest  die Struktur, Ordnernamen und Dateinamen müssen synchronisiert werden. Bestimmte Informationen liegen auch im Cache, der auch aufgeräumt werden sollte.

Aufruf der Ausführen App

Dazu geben Sie bei ihrem Windows 10 im Suchfenster links unten den Begriff “Run” ein un bestätigen Sie die App “Run”

Kopieren sie die nachfolgendes Kommando und fügen es  in der Open Zeile ein

%localappdata%\Microsoft\OneDrive\onedrive.exe /reset


Befehl ausführen

Jetzt wird OneDrive erst einmal beendet. Danach wird ein Reset auf alle Synchronisierungen gebildet und es wird ein Abgleich durchgeführt. Sollte auch nach mehreren Minuten keine Symbol in der Benachrichtigungszeile rechts unten erscheinen so können Sie nach der obigen Methode den OneDrive Client neu starten.

Der Befehl lautet jetzt:


ich habe oben das Mengengerüst dargestellt, denn es wird schon eine geraume Zeit dauern, bis der Abgleich von 62.942 Dateien in 2089 Ordner erfolgt ist. Bedeutet, abhängig vom der Bandbreite des Internetzugangs, der Anzahl von Dateien, der Rechnergeschwindigkeit dauert ein Reset unterschlich lange.

Gebt dem Rechner also eine Chance…

OneDrive: new Symbols in Version 19.074.0416.0001

new OneDrive Icons

I can only smile about that. but many are happy about it. About the new icons and icons. And in the new insider version 19.074.0416.0001 (Office) of the Next Generation Sync Client (OneDrive.exe), the new Icon of the OneDrive also moves into the notification area of the Task Bar.

The old symbol has not disappeared everywhere yet. Also in the Insider Windows version 1903, the old symbol is still visible in various places. It is well known that taste can be disputed, but lacking functionality is not. And Microsoft would do well to keep up the good work and push the integration of SharePoint libraries into Windows Explorer (presentation level) and the associated intelligence in Office products.

I can not say anything about new functionality. As usual, nothing is said about the insider versions.

I do not know when the new icons will be integrated into the production ring for all other users

OneDrive: neue Symbole in Version 19.074.0416.0001

Neue OneDrive Icons

ich kann darüber nur Lächeln, aber viele freuen sich darüber. Über die neuen Symbole und Icons. Und in der neuen  Insider-Version 19.074.0416.0001 (Office) des Next Generation Sync Client (OneDrive.exe) zieht das neue Icon des OneDrive auch in der Benachrichtigungszeile ein.

neue OneDrive Icons

Noch ist das alte Symbol nicht überall verschwunden. Auch in der Insider-Windows Version 1903 ist das alte Symbol noch an diversen Stellen zu sehen. Über Geschmack lässt sich bekanntlich streiten, über fehlende Funktionalität jedoch nicht. Und Microsoft tut gut daran, hier nicht locker zu lassen und Integration von SharePoint Bibliotheken in den Windows Explorer (Präsentation-Ebene) und die damit verbunden Intelligenz in Office-Produkte weiter voran zu treiben.

Über neue Funktionalität kann ich nichts berichten. Wie üblich wird über die Insider-Versionen nichts bekannt gegeben.

Ich weiß nicht den Zeitpunkt, wann die neuen Symbole für alle anderen Benutzer in den Produktions-Ring integriert werden

OneDrive | Update for GPO team site libraries to sync automatically

4. April 2019 9 Kommentare

Group Policy: Configure team site libraries to sync automatically

I have written an article about “OneDrive GPO: Configure team site libraries to sync automatically” and I must update this article.

First, and that is important: If we are looking inside the OneDrive Group Policies, you will see, there is a Group Policy in both parts (Machine and User) with the same name

Configure team site libraries to sync automatically

I have described the GPO, which is a Machine policy. But there are other Scenario’s with more than one user and Microsoft has decided, to have the same Group Policy also in the Users Section.

Local Group Policy Editor: Computer

Local Group Policy Editor: User

The name is the same. The group Policy looks like the same. The Functionality is the same. Only the Key in the Regedit is different


[HKLM\SOFTWARE\Policies\Microsoft\OneDrive\TenantAutoMount] "LibraryName"="LibraryID"




Why Microsoft decided to have the same Group Policy in the Users section?

Its very easy, because if you look for devices, where different people from different departments will login, then there is the answer. If you have a machine policy, you are only may connect to team sites, where all possible users have the rights. Changing that to a User Policy, you may have to rollout several different GPOs, that will only work with this subset of AD.

Other questions received me, thank you, and I try to give you the right answer:

Why do we have the limit of 1000 devices?

We have to know, how OneDrive is working. Microsoft uses Windows Push Notification Services (WNS) to sync files in real time. The main important part is: WNS informs the sync client whenever a change actually happens, eliminating redundant polling and saving on unnecessary computing power. So on the Server side:

  • A change occurs in Office 365.
  • WNS alerts the OneDrive sync client of the change.
  • OneDrive adds it to the Internal Server Changes Queue.
  • – Any metadata changes happen immediately, like renaming or deleting files.
  • – Downloading content also starts a specific session with the client.
  • Office 365 has metadata pointers directing it through Microsoft Azure.
  • The changes are processed in the order they are received.

The previous OneDrive for Business sync client (Groove.exe) used a polling service to check for changes on a predetermined schedule. Polling can lead to system lag and slowness because it requires a lot of computing power. Using WNS is a significant enhancement.

Now back to our question: WNS has one limit: 1000.

This is the current limit of devices that can subscribe through the WNS pipeline to get notifications from the service about file changes. After that limit is reached, the remaining clients will go into polling mode, which means they will poll the service every few minutes to see if there are any changes.

Why does take up to 8 hours, until the client machine receives the files?

This is because of the potential spike of requests of mounting a team site both on the customer’s network as well as on the backend service.

This Group Policy is in Preview. Microsoft will see on telemetry data, how this Group policy will be used. In other words. It could be change in the future
