How to deploy PowerPivot/Power BI in Office 365 SharePoint Online?

We have several users on Office 365 (E2 Subscription) who have Excel 2013 and PowerPivot on their individual computers who would like to place PowerPivot apps on SharePoint for users without Excel to view.
How can we do this?

Your users can do this now if interactivity isn't required. If it is, you'll need to move up to an E3 plan. If your models exceed 10 MB, and you want interactivity, you'll need Power BI licenses for your users.

How to visualize the power map in office 365 or share point 2013??

Hi,
I have designed the power map within excel.
Here power map can be able to saw within excel, but i need to visualize to web browser like share point 2013 or office 365.
Anyone know how to display it?
Thanks,
Ramu

With Power Map you have the ability now to create a video of the tour when you are done. You can then use this video file to share the tour in SharePoint, in Power Points, YouTube, etc.
http://office.microsoft.com/en-us/excel-help/export-a-power-map-tour-as-a-video-HA104106952.aspx
At this point this is the only way to share the tours unless you open up the Excel file and launch Power Map.

How to use Blob storage to office 365 sharepoint online library documents

Hello,
Considering that we cant uploade a file with size more than 250 MB and it is recommended using Remote
Blob Storage (RBS) if large files are supposed to store in SharePoint.
My question is, how to use RBS or Azure Blob storage to store files instead of SQL database.
What is the configuration or code i need to write to accomplished this where i would prefer if it can be done simply using some configuration.
any sample or tutorial would be great help.
Thanks,
Asjad

HI,
What we did, we deploy small Azure PaaS application what used Azure Blob Storage and table and then show it in Office365 SharePoint online trough iframe. This gives you flexibility to customimze the PaaS application and show the content at blog storage.
We tested this in SharePoint ONline multitenant and Dedicated plus in On Premise SharePoint with the custom code in separate IIS server published trough UAG to Internet. This allows you to save or replace your file server with Azure and small PaaS apps in
and show the content on SharePoint ONline trough Iframe.

How to create a private forum in Office 365 SharePoint for customers?

Hi,
I am implementing a SharePoint Office 365 solution for a client but one of their requirements is sharing regularly updated info with only 20 customers. The idea is to share info with just the customers in a private forum basically to receive feedback, comments
and emails. What is the best approach to this?
Thanks,

Hello Aslr12,
Based on these requirements I would just create a new site collection within SharePoint online service of your Office 365 tenant, based on the community site template. This template has some nice web parts like the Discussion list and some Community tools.

Hi,
According to your post, my understanding is that you had an issue to connect to the SharePoint online.
I had tested with your code, and it worked well as below.
Did your project contain other code? Such as parse the XML file?
You can create a new clean project to check with it works.

Access denied office 365 / SharePoint online with Global Admin account

Hi All,
I am going crazy since two days solving an issue. The problem is;
I am making a console APP which is talking to SharePoint Online using global admin account (One which was specified as admin while making a new subscription). What I am trying to achieve is, I want to add a custom action using CSOM to each site collection and
subsite of office 365. That code works fine except on the root site collection which is pre-created by office 365 while signing up (i.e. https://xyz.sharepoint.com)
Whatever I do on that site collection, it says gives me below error;
"SchemaVersion":"15.0.0.0","LibraryVersion":"16.0.3912.1201","ErrorInfo":{
"ErrorMessage":"Access denied. You do not have permission to perform this action or access this resource.","ErrorValue":null,"TraceCorrelationId":"2a47fd9c-c07b-1000-cfb7-cdffbe3ab83a","ErrorCode":-2147024891,"ErrorTypeName":"System.UnauthorizedAccessException"
},"TraceCorrelationId":"2a47fd9c-c07b-1000-cfb7-cdffbe3ab83a"
Now the user is global admin. I also added again that user as site collection admin.
The same piece of code works fine on other site collections (search site collection, any newly made site collection...).
here is a code;
using (ClientContext spcollContext = new ClientContext(web.Url))
SecureString passWord = new SecureString();
foreach (char c in strAdminPassword.ToCharArray()) passWord.AppendChar(c);
SharePointOnlineCredentials creds = new SharePointOnlineCredentials(strAdminUser, passWord);
spcollContext.Credentials = creds;
Web currentweb = spcollContext.Web;
spcollContext.Load(currentweb);
spcollContext.ExecuteQuery();
// authCookie = creds.GetAuthenticationCookie(new Uri(web.Url));
var existingActions2 = currentweb.UserCustomActions;
spcollContext.Load(existingActions2);
spcollContext.ExecuteQuery();
var actions2 = existingActions2.ToArray();
foreach (var action in actions2)
if (action.Description == "CustomScriptCodeForEachsite" &&
action.Location == "ScriptLink")
action.DeleteObject();
spcollContext.ExecuteQuery();
var newAction2 = existingActions2.Add();
newAction2.Description = "CustomScriptCodeForEachsite";
newAction2.Location = "ScriptLink";
newAction2.ScriptBlock = scriptBlock;
newAction2.Update();
spcollContext.Load(currentweb, s => s.UserCustomActions);
spcollContext.ExecuteQuery(); // GETTING ERROR ON THIS LINE.
Note: Above error is Fiddler traces.

Office 365 SharePoint online: How to create multi level top Navigation

I having a requirement that we have a site structure which contains departmental sites and each site have multiple subsites.
eg:
Site 1:
sub site 1
Sub site 2
Site 2:
sub site 1
sub site 1 (last node)
sub site 2 (last node)
Sub site 2
Site 3
and so on.
I have to show site structure in top navigation, can you guide me how can we achieve this using SharePoint Design Manager or if their is any other way then please tell me.

In snippet gallery, select top navigation from Ribbon, it will show snippet and customization details.
In Customization - Top Navigation (ASP.NET) section, expand
Important node and change value of StaticDisplayLevels
to 2. After that expand Behavior node and change value of
MaximumDynamicDisplayLevels to 2.

How to download a file version from office 365 using csom

I need to download an older file version from office 365 and get the data into a byte array. I have no trouble downloading the latest version with File.OpenBinaryStream() and I have no trouble loading the previous file versions with File.Versions. But now
I need to actually download an older version of the file and it seems the only way is to use File.OpenBinaryDirect. So I am creating a client context using my oAuth access token and providing the correct path, but I am getting a (401) Unauthorized
error. Looking with Fiddler I can see that the call to OpenBinaryDirect is somehow trying to post to my file URL and the server is responding with 401.
context = TokenHelper.GetClientContextWithAccessToken(SPHostUrl, AccessToken);
FileInformation info = File.OpenBinaryDirect(context, "/" + _fileVersion.Url); //throws 401
//leading slash required otherwise ArgumentOutOfRangeException
I have to be able to access the older file versions with my c# code -- I don't have a viable app without that ability -- any help urgently needed and greatly appreciated!

Thank you SO much (Can't wait for the next release)!
For anyone else who lands here, here's the code I ended up using:
// VersionAccessUser and VersionAccessPassword are stored in web.config
// web.Url is loaded via the clientContext
// myVersion is the FileVersion I got from the file's Versions.GetById() method
// probably a lot of ways to get hostUrl, it just needs to be https://yourdomain.sharepoint.com/
// - I'm running my app from a subweb
// I had trouble following the links to get the full MsOnlineClaimsHelper code
// (the one on msdn.com was missing RequestBodyWriter, WSTrustFeb2005ContractClient,
// and IWSTrustFeb2005Contract
// so I've included the code I used here.
string myVersionFullUrl = string.Format("{0}/{1}", web.Url, myVersion.Url);
string userName = WebConfigurationManager.AppSettings.Get("VersionAccessUser");
string strPassword = WebConfigurationManager.AppSettings.Get("VersionAccessPassword");
string hostUrl = Regex.Replace(web.Url, "([^/]+//[^/]+/).*", "$1");
MsOnlineClaimsHelper claimsHelper = new MsOnlineClaimsHelper(hostUrl, userName, strPassword);
var client = new WebClient();
client.Headers["Accept"] = "/";
client.Headers.Add(HttpRequestHeader.UserAgent, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
client.Headers.Add(HttpRequestHeader.Cookie, claimsHelper.CookieContainer.GetCookieHeader(new Uri(hostUrl)));
var document = client.DownloadString(myVersionFullUrl);
// These classes are needed to download old versions of files (see: http://social.msdn.microsoft.com/Forums/en-US/7746d857-d351-49cc-b2f0-496663239e02/how-to-download-a-file-version-from-office-365-using-csom?forum=sharepointdevelopment)

Publish wsp file to office 365 - sharepoint

Dear,
How can i deploy a wsp file to sharepoint on office 365?
For example i want to publish the WireBaer print button to print an item from a list
(https://infopathprinter.codeplex.com/)
Thx in advance!

Hi,
According to your description, my understanding is that you want to deploy the wsp file to Office 365 SharePoint site.
I suggest you can upload the wsp file to site settings-> solutions gallery, then you can activate the feature in the ribbon.
Here is a similiar thread for your reference:

How to delete the exceed threshold limit list in Sharepoint Online

In my share point online list having more than 5000 items. It's reached threshold limit.Then
i am trying to delete the list data using client context in console application. But I got this error message "The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator."
If anyone know how to resolve this issue.

Hi,
Unfortunately there is no option to override the list threshold in Office 365/SharePoint Online. One option is to create the folders and move the items to that folders, then try deleting the items.
And also refer to the following posts.

Copying Document Across Site Collections to Dynamic Locations - Office 365 / SharePoint

I have users uploading documents into a library in one site collection and adding a reference number to each file (text box - list item). Can I use that reference number to find a corresponding folder on a different site collection and programmatically
copy the file to that location? The reference number is part of the name of the folder. SharePoint Designer, Visual Studio, Napa - whichever is easiest. Using Office 365 / SharePoint Online.
Thanks!

Hi,
If the reference number plus with the file name is valid and unique, we will be able to find the wanted folder across site collections by querying this file and its parent folder.
As the reference number + file name is just a string value of a column of a library, we may need to iterate through all the libraries and check whether there is such a file with
CAML query statements.

No Power BI for Office 365 License???

Hi,
we have installed the free Power BI SharePoint App. We have assigned the free license to two users.
It now says correctly that we have 999998 of 1000000 licenses left. So far, so good :-)
But...when I click "Power BI" in the left navigation pane, the App seems to start but then:
"Keine Power BI für Office 365-Lizenz
Sie besitzen anscheinend keine Benutzerabonnementlizenz für Power BI für Office 365."
Which means in english: "No Power BI for Office 365 License...You don't have a user subscription license for Power BI for Office 365".
But we do have assigend the license to these two users!
Anybody have an idea what I can do?
We would even pay for Power BI but there is no link where we can buy the full license?
Thanks
Malte

I have the same problem as Jamie
I added Power BI to my E4 subscription. However, when trying to access Power BI link on the left side of the screen, i get "No Power BI for Office 365 License" ask your admin.
I'm one of the office 365 admins and have a license assigned to myself already. I have deleted the app and re-added it with no luck so far.
Can you help please and suggest how to fix this?
Thank you so much in advance for your help
