It always happen, and therefore I will point to the Original Website from Microsoft, where all Limitation and restrictions for the OneDrive, OneDrive for Business and SharePoint are listed

In the past this was behind the Knowledge Base Article KB 315202 (This article does not exist anymore, KB315202 was deleted)

So you have to use this Link

OneDrive | file length 2GB, 4 GB, 8 GB or unlimited?

4. September 2014 2 Kommentare


Sometime Microsoft announced  new things about products weeks and month ahead. Since marketing plays a great role, to show the competitors, what will happen in the near future. So also with the consumer product OneDrive.

Omar Shahin, Microsoft Manager announced on 23 June 2014 on the Microsoft OneDrive blog that the available memory is increased in the cloud. I have written about that here.

Now, however, Microsoft holds back information. Because in the near future Microsoft will drop the 2 GB file size limitation in OneDrive. Also I have written about it here. And had the good fortune to experience this lifting this limit already. What is not clear, where are the new limits?

Therefore I have generated several files in form of virtual disks with exact, but different size and tries to synchronize these files:

OneDrive: new file lenght limit: 10 GB

while file sizes> = 10 GB with an error message at the start of the synchronization were displayed, I could synchronize a file with 9 GB in my OneDrive.
This means that the new restriction is a single file with 10 GB. Now you do not have to try it with your files, because the official statement from Microsoft is still pending.


However, there are a few limitations:
The files can only be synchronized in Windows Explorer. Tested: Windows 7 SP1 with the OneDrive program and Windows 8.1 (OneDrive native in Windows 8.1 included)


Before you get started: If you have multiple devices in use and want synchronize files using OneDrive, you should look at your capacity of each device exactly. I have as a Surface RT (1st generation) and on this device I have little space on it. That’s why I created a folder for the large files, and this is set to "Only Available online".


OneDrive: over 250 million users

Since more than 250 million users work with OneDrive, these data are in various Microsoft data centers on different servers. And they must all be brought on the server side to the new state. This can already take a considerable time to complete. And that will be the reason why Microsoft has not made any statement about this change.

OneDrive for Business

And on the Internet, many users ask, what things look like with OneDrive for Business?

There was an official Microsoft statement at SPC24 (SharePoint Conference 2014 in Las Vegas): The 2 GB limit will raise at the end of year 2014 to 10 GB


Again, the consumer program OneDrive is one step ahead, but that will change in the near future, both Microsoft developer teams (OneDrive and OneDrive for Business) work together under common leadership. But about that I will write another blog post.

OneDrive for Business | Limitations

OneDrive for Business, Microsoft

OneDrive for Business has several limitations. For example, in the filename. Or with the prefix “_” in the filename.  Bill Baer, Senior Product Marketing Manager by Microsoft, has published on TechNet an article about several problems with filenames. Most of them has her origin on SharePoint Server. But not at all:

Problem description
Location on SD card if you have a SD card on your device, you cannot use this card to take this as a location for OneDrive for Business data.
Roaming Profiles For OneDrive for Business it is not possible to use it with roaming profiles.
network drives You cannot use OneDrive for business on a network drive. Therefore, and this is a great custom wish, you cannot give OneDrive for business with a fixed drive letter.
You will find several instructions on the internet, how to do that. Sometimes they will work, Sometimes not. Or not anymore.
That’s a a question about many parameters, like OS and so on.

With these restrictions it is not possible, f.e to use it on a campus with several fixed machines, to use OneDrive for Business with local synced data. If you have such an environment, you should disable OneDrive for Business with OAT before deployment, or If you have still deployed, restrict the usage with GPO (group policies).

But this will always work: Use the web-Browser to connect to your SharePoint Server 2013 (on prem) or SharePoint Online (Office 365). Then you may able to work with Office Online on your documents. And you may do Co-Authoring. And that not only with you personal data in OneDrive for business, fka Mysite. Also on all documents in team sites, where you may have access. If you may not able to work with Office Online on a specified document, you may download this document to your device. But not a complete local synchronization of all documents at all.

Admins should enable access to these documents from “outside”, then users may access these data on her own devices, and here they may synchronize all data on these devices for offline usage. And that not only with windows devices…
