Security of SharePoint Online

We are using Sharepoint Online and Sharepoint 2010 on Prem. Can someone tell me if you have sensitive data that is deleted on a site level and then deleted on the top level if it is completed removed from the SharePoint databases?

Artifacts may remain in either scenario. For example, if audit logging was enabled, and the item was referenced in it, evidence of that reference may exist.
Microsoft also maintains a level of backups within SPO, so the item may be retrievable from backups (but this has to be specifically requested via a support ticket).

How to set security group as primary site collection admin and secondary site collection admin using powershell in sharepoint online site - office 365?

Hi,
According to your description, my understanding is that you want to set security group as admin of primary and secondary site collection using PowerShell command in office 365.
I suggest you can use the command below to set the group to site owner, then it will have the site collection admin permission.

Call an Non-SharePoint Secured RESTful API from a Workflow in a SharePoint Online Tenant

I have a scenario where I need to be able to make calls to a secured web service from a SharePoint 2013 workflow that will be deployed in a SharePoint Online (Office 365) environment. It is a REST web service that is secured in a 2-legged OAuth-like manner
(the service expects a hash of the data being sent that can then be validated on the service's end of the communication). The problem is, I can't figure out how I can hash the data, since I can't run any server-side code in the SharePoint Online environment.
The way I figured this should work is 1) user creates an item in a List on the SharePoint Site, which kicks off the workflow process. 2) the workflow process takes the user data and hashes it using a client secret assigned by the web service. 3) the
workflow creates a web request to the web service, passing the data and the hashed values. 4) the web service processes the input and returns. 5) the workflow continues to the next step.
I can't figure out how to implement step 2 in that process. I thought I could do a custom workflow activity that would accomplish it, but since it would pretty much have to be a code-based activity (i.e., not declarative), it can't be deployed in SharePoint
Online, according to the domentation I've found. I could potentially add a third layer in the process and have an auto-hosted app that I could call to do the hashing of the data, but that seems to defeat the purpose somewhat from a security perspective.
Has anyone else run into this kind of scenario? Doing this in an on-premesis environment would be easy, but that's not really an option.
Thanks!

You should implement this by passing the values to a public (forms based auth) web method (secure over SSL) that does the hash for you and returns the value to your workflow so that it can pass it on to the other service.

Security flaw-To use CSOM/Javascript code for Custom Office365(Sharepoint Online) application

Hi,
I've developed custom application in Office365(Sharepoint Online) using CSOM/Javascript. Security team from client side has been reported one major issue to the our application that any end user can comment our CSOM/Javascript code and bypass the validation
or can update / insert into sharepoint list item using developer tool/ Console in Google Chrome(F12 Key).
Also end user can write his own separate code in console of Google Chrome (Developer Tool / F12) and can update / insert into Sharepoint List.
Note:- End user has Add, Edit, View permission on all Sharepoint List.
This is one major security flaw of the Sharepoint/Office365 to use CSOM /Javascript for writing code, to overcome this issue could you please provide me some solution.
Your help would be greatly appreciated!!!
Looking for reply.
Thanks,

Office365 Exchange Security Group not updating in Sharepoint Online

We have created a new Office365 Exchange Security Group that contains several other Exchange Security Groups. This group will not show up in either the SharePoint Web admin or SharePoint Designer views.
How can I force SharePoint to re-synchronize the Office365 Tenant users/groups?

Hi,
According to your post, my understanding is that Office365 Exchange Security Group does not updating in Sharepoint Online.
How long did you wait after creating the Group to see if they show up in SharePoint Online? The back-end replication can take some time, even days from my experience.
Here is a similar thread for your reference:

ADFS SSO and SharePoint 2013 on-premise Hybrid outbound search results from SharePoint Online - does it work?

Hi,
I want to setup an outpund hybrid search for SharePoint 2013 on-premise to SharePoint Online.
But I'm not shure if this works with ADFS SSO.
Has somebody experience with this setup?
Here's my guide which I'm going to use for this installation:
Introduction
In this post I'll show you how to get search results from your SharePoint Online in your SharePoint 2013 on-premise search center.
Requirements
User synchronisation ActiveDirectory to Office 365 with DirSync
DirSync password sync or ADFS SSO
SharePoint Online
SharePoint 2013 on-premise
Enterprise Search service
SharePoint Online Management Shell
Instructions
All configuration will be done either in the Search Administration of the Central Administration or in the PowerShell console of your on-premise SharePoint 2013 server.
Set up Sever to Server Trust
Export certificates
To create a server to server trust we need two certificates.
[certificate name].pfx: In order to replace the STS certificate, the certificate is needed in Personal Information Exchange (PFX) format including the private key.
[certificate name].cer: In order to set up a trust with Office 365 and Windows Azure ACS, the certificate is needed in CER Base64 format.
First launch the Internet Information Services (IIS) Manager
Select your SharePoint web server and double-click Server Certificates
In the Actions pane, click Create Self-Signed Certificate
Enter a name for the certificate and save it with OK
To export the new certificate in the Pfx format select it and click Export in the Actions pane
Fill the fields and click OK Export to: C:\[certificate
name].pfx Password: [password]
Also we need to export the certificate in the CER Base64 format. For that purpose make a right-click on the certificate select it and click on View...
Click the Details tab and then click Copy to File
On the Welcome to the Certificate Export Wizard page, click Next
On the Export Private Key page, click Next
On the Export File Format page, click Base-64 encoded X.509 (.CER), and then click Next.
As file name enter C:\[certificate
name].cer and then click Next
Finish the export
Import the new STS (SharePoint Token Service) certificate
Let's update the certificate on the STS. Configure and run the PowerShell script below on your SharePoint server.
if(-not (Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue)){Add-PSSnapin "Microsoft.SharePoint.PowerShell"}
# set the cerficates paths and password
$PfxCertPath = "c:\[certificate name].pfx"
$PfxCertPassword = "[password]"
$X64CertPath = "c:\[certificate name].cer"
# get the encrypted pfx certificate object
$PfxCert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2 $PfxCertPath, $PfxCertPassword, 20
# import it
Set-SPSecurityTokenServiceConfig -ImportSigningCertificate $PfxCert
Type Yes when prompted with the following message.
You are about to change the signing certificate for the Security Token Service. Changing the certificate to an invalid, inaccessible or non-existent certificate will cause your SharePoint installation to stop functioning. Refer
to the following article for instructions on how to change this certificate: http://go.microsoft.com/fwlink/?LinkID=178475. Are you
sure, you want to continue?
Restart IIS so STS picks up the new certificate.
& iisreset
& net stop SPTimerV4
& net start SPTimerV4
Now validate the certificate replacement by running several PowerShell commands and compare their outputs.
# set the cerficates paths and password
$PfxCertPath = "c:\[certificate name].pfx"
$PfxCertPassword = "[password]"
# get the encrypted pfx certificate object
New-Object System.Security.Cryptography.X509Certificates.X509Certificate2 $PfxCertPath, $PfxCertPassword, 20
# compare the output above with this output
(Get-SPSecurityTokenServiceConfig).LocalLoginProvider.SigningCertificate
[/code]
## Establish the server to server trust
[code lang="ps"]
if(-not (Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue)){Add-PSSnapin "Microsoft.SharePoint.PowerShell"}
Import-Module MSOnline
Import-Module MSOnlineExtended
# set the cerficates paths and password
$PfxCertPath = "c:\[certificate name].pfx"
$PfxCertPassword = "[password]"
$X64CertPath = "c:\[certificate name].cer"
# set the onpremise domain that you added to Office 365
$SPCN = "sharepoint.domain.com"
# your onpremise SharePoint site url
$SPSite="http://sharepoint"
# don't change this value
$SPOAppID="00000003-0000-0ff1-ce00-000000000000"
# get the encrypted pfx certificate object
$PfxCert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2 $PfxCertPath, $PfxCertPassword, 20
# get the raw data
$PfxCertBin = $PfxCert.GetRawCertData()
# create a new certificate object
$X64Cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
# import the base 64 encoded certificate
$X64Cert.Import($X64CertPath)
# get the raw data
$X64CertBin = $X64Cert.GetRawCertData()
# save base 64 string in variable
$CredValue = [System.Convert]::ToBase64String($X64CertBin)
# connect to office 3656
Connect-MsolService
# register the on-premise STS as service principal in Office 365
# add a new service principal
New-MsolServicePrincipalCredential -AppPrincipalId $SPOAppID -Type asymmetric -Usage Verify -Value $CredValue
$MsolServicePrincipal = Get-MsolServicePrincipal -AppPrincipalId $SPOAppID
$SPServicePrincipalNames = $MsolServicePrincipal.ServicePrincipalNames
$SPServicePrincipalNames.Add("$SPOAppID/$SPCN")
Set-MsolServicePrincipal -AppPrincipalId $SPOAppID -ServicePrincipalNames $SPServicePrincipalNames
# get the online name identifier

$MsolServicePrincipalID = (Get-MsolServicePrincipal -ServicePrincipalName $SPOAppID).ObjectID
$MsolNameIdentifier = "$MsolServicePrincipalID@$MsolCompanyInformationID"
# establish the trust from on-premise with ACS (Azure Control Service)
# add a new authenticatio realm
$SPSite = Get-SPSite $SPSite
$SPAppPrincipal = Register-SPAppPrincipal -site $SPSite.rootweb -nameIdentifier $MsolNameIdentifier -displayName "SharePoint Online"
Set-SPAuthenticationRealm -realm $MsolServicePrincipalID
# register the ACS application proxy and token issuer

New-SPTrustedSecurityTokenIssuer -MetadataEndpoint "https://accounts.accesscontrol.windows.net/metadata/json/1/" -IsTrustBroker -Name "ACS"
Add a new result source
To get search results from SharePoint Online we have to add a new result source. Run the following script in a PowerShell ISE session on your SharePoint 2013 on-premise server. Don't forget to update the settings region
if(-not (Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue)){Add-PSSnapin "Microsoft.SharePoint.PowerShell"}
# region settings
$RemoteSharePointUrl = "http://[example].sharepoint.com"
$ResultSourceName = "SharePoint Online"
$QueryTransform = "{searchTerms}"
$Provier = "SharePoint-Remoteanbieter"
# region settings end
$SPEnterpriseSearchServiceApplication = Get-SPEnterpriseSearchServiceApplication
$FederationManager = New-Object Microsoft.Office.Server.Search.Administration.Query.FederationManager($SPEnterpriseSearchServiceApplication)
$SPEnterpriseSearchOwner = Get-SPEnterpriseSearchOwner -Level Ssa
$ResultSource = $FederationManager.GetSourceByName($ResultSourceName, $SPEnterpriseSearchOwner)
if(!$ResultSource){
Write-Host "Result source does not exist. Creating..."
$ResultSource = $FederationManager.CreateSource($SPEnterpriseSearchOwner)
$ResultSource.Name = $ResultSourceName
$ResultSource.ProviderId = $FederationManager.ListProviders()[$Provier].Id
$ResultSource.ConnectionUrlTemplate = $RemoteSharePointUrl
$ResultSource.CreateQueryTransform($QueryTransform)
$ResultSource.Commit()
Add a new query rule
In the Search Administration click on Query Rules
Select Local SharePoint as Result Source
Click New Query Rule
Enter a Rule name f.g. Search results from SharePoint Online
Expand the Context section
Under Query is performed on these sources click on Add Source
Select your SharePoint Online result source
In the Query Conditions section click on Remove Condition
In the Actions section click on Add Result Block
As title enter Results for "{subjectTerms}" from SharePoint Online
In the Search this Source dropdown select your SharePoint Online result source
Select 3 in the Items dropdown
Expand the Settings section and select "More" link goes to the following URL
In the box below enter this Url https://[example].sharepoint.com/search/pages/results.aspx?k={subjectTerms}
Select This block is always shown above core results and click the OK button
Save the new query rule

Hi Janik,
According to your description, my understanding is that you want to display hybrid search results in SharePoint Server 2013.
For achieving your demand, please have a look at the article:
http://technet.microsoft.com/en-us/library/dn197173(v=office.15).aspx
If you are using single sign-on (SSO) authentication, it is important to test hybrid Search functionality by using federated user accounts. Native Office 365 user accounts and Active Directory Domain Services
(AD DS) accounts that are not federated are not recognized by both directory services. Therefore, they cannot authenticate using SSO, and cannot be granted permissions to resources in both deployments. For more information, see Accounts
needed for hybrid configuration and testing.

Is Office Home and Business 2013 fully compatible with Sharepoint Online (Office 365)?

My client recently upgraded 3 Windows 7 PCs (2-32 & 1-64-bit OS) from Office 2007 32-bit (which was actually working fine against Exchange/SharePoint Online) to Office Home and Business 2013 (32-bit)
Now, for all 3 PCs, while Office 2013 Word/Excel can open, check out/in, and save SharePoint Online files, there is ALWAYS a 2 minute delay in closing the file which is apparently waiting for the Local Security Authority call to return. This seems
to indicate an issue related to SharePoint security on the client side.
Problem Event Name: AppHangXProcB1
Application Name:
WINWORD.EXE
Application Version:
15.0.4657.1000
Waiting on Application Name:
lsass.exe:lsasspirpc
This is the Local Security Authority Security Support Provider Interface Remote Procedure Call (LSA SSPI RPC)
My client has 66 licenses for SharePoint Online (Plan 2) and 73 Exchange Online (Plan 1) "stand alone" services. The same failure is happening on 3 Win 7 PCs. All of which I've carefully reviewed against the MS Office trouble shooting guides (start
Windows OS w/out non-MS services, Word/Excel safe mode w/out add-ons, O365 readiness checks, Office repair, etc.). We have PCs running Win 7 (32 & 64-bit) w/Office 365 ProPlus & Office Professional Plus 2013 that work fine. it's JUST these 3 Win 7
PCs that were upgraded from Office 2007 to Office Home and Business 2013 that have the 2 min. SharePoint file close time.
Can you please confirm that Office Home and Business 2013 is compatible w/SharePoint Online
at least for Excel and Word?
The "slow close" problem can be demonstrated on multiple site collections/sub sites and w/Excel & Word docs in doc libs and lists
After many hours capturing information, following the MS Office trouble shooting guides, and repairing the Office install, I've had no luck in resolving this.While Word/Excel will eventually close SharePoint Online files after about
2 minutes, this is certainly unacceptable. Otherwise, locally stored files close normally and new files were created by the Office 2013 Excel/Word for this testing.
Any thoughts or guidance would be appreciated.

Hi raygabe,
I couldn't find the document mentioned there is any compatibility between Office365 SharePoint online and Office Home and Business 2013 version, I would recommend that you check if the issue could be reproduced on other Win7 machines installed with Office
Home and Business 2013 installed directly instead of upgrading from Office2007, see if issue is related to Office application upgrade.
I also recommend that you post this issue on our dedicated Office365 SharePoint online forum and Office 2013 forum for a better assistance with more experts regarding this issue from the following links.

Can't open Sharepoint Online site in Sharepoint Designer 2013

Hello!
I am trying to open a Sharepoint Online secure site in Sharepoint Designer 2013 (v15). When I try to open the site in Sharepoint Designer i get an error stating:
"Server error: The version of Microsoft SharePoint Foundation running on the server is more recent than the version of SharePoint Designer that you are using. You need a more recent version of SharePoint
Designer."
I used to have the preview version installed, but I uninstalled it and got the latest version I could find (version 15?). I checked the SharePoint version on the server (/_vti_pvt/service.cnf) and it says:
vti_encoding:SR|utf8-nl
vti_extenderversion:SR|16.0.0.1706The public site I have has the same version and it opens just fine in SharePoint Designer 2013. Are there any new versions of SharePoint Designer 2013 available that I have missed? My SharePoint Designer is up to date via Windows Update.I am running the designer on Windows 7 Ultimate x86.

I had the same issue today. Here what I have found.
I was using different credentials for my different SharePoint site in SPD 2013. When I try to access my new SharePoint online site (Which has different Account) the SharePoint Designer directly show me
"Server error: The version of Microsoft SharePoint Foundation running on the server is more recent than the version of SharePoint Designer that you are using. You need a more recent version of SharePoint Designer."
then I changed my Account Credentials by
Open SPD 2013
1)click File
2) Click Account
3) Log out from current user name
4) sign in by using the same credential as your new SharePoint Site.
DONE!
I think this error is not useful as it (this error) is not about which version of SharePoint you are using but more about Account credentials.(At least for me) Hope that helps.

Issue in adding new items to a O365 SharePoint Online List having lookup columns (Client Object Model)

I have two Lists i.e. Publisher and Products in my SharePoint Online site. They are having the following structures:
1. Publisher:
Publisher (Single line of txt)
     A1
     A2
     A3
     A4
     A5
     A6
2. Products:
Publisher (lookup to the above column)
ProductName (Single line of txt)
     A1                                                                   Apple

But I'm getting the following error on running the above code "Invalid data has been used to update the list item. The field you are trying to update may be read only."
Can anybody please help me out?

Hi,
According to your description, my understanding is that you want to update data to look up field.
I have a test about updating look up field using Client Object Model in my environment. lookup field will accept an array to set the field value.
Here is the code snippet:
Microsoft.SharePoint.Client.ClientContext ctx = new ClientContext("http://sp2013sps/sites/test/");
if (ctx != null)
List list = ctx.Web.Lists.GetByTitle("List3");
ListItem itemToUpdate = list.GetItemById(1);
ctx.Load(itemToUpdate);
ctx.ExecuteQuery();
FieldLookupValue newLookUpField = new FieldLookupValue();
newLookUpField.LookupId = 3;
FieldLookupValue newLookUpField1 = new FieldLookupValue();
newLookUpField1.LookupId = 4;
FieldLookupValue[] newarr = { newLookUpField, newLookUpField1 };
itemToUpdate["lookup"] = newarr;
itemToUpdate.Update();
ctx.Load(itemToUpdate);
ctx.ExecuteQuery();

I have several subsites on a SharePoint 2013 server that uses external content types and the Business Data Connectivity Service to access tables in a SQL Server database. I used the Sharepoint 2013 Designer to configure most of this, but at times, I also
used Visual Studio 2013. Everything works fine. It successfully uses a secure store Application ID to authenticate connections to a remote SQL Server (i.e. the SQL Server and SharePoint server are 2 completely different machines that are not even within the
same domain). The external lists on the SharePoint site are capable of reading data in the SQL tables, updating data, adding new data, and deleting old data. I have specified permissions to users/groups that help me control who can access the external lists
on the SharePoint sites. Everything has been working well for a while now.
But now I have to start thinking about using SharePoint Online, instead of an on-premises SharePoint server. And everything I am reading indicates that what I do above is not going to work with SharePoint Online. It sounds like I will have to either move
our database to a SQL Azure service, or if I want to continue using our existing SQL Server, then I am going to have to develop a WCF service that will allow SharePoint Online to communicate with our own SQL Server. Am I understanding this correctly? Or is
there a way to take what I did above and make it work with SharePoint Online?
Thank you,
Steven

Hi,
We can use Hybrid Connections to connect SharePoint Online to an on-premises SQL Server.
Here is a blog from MSDN for your reference:

We can also customize a WCF service and publish it to public web site to achieve it.

Hi,
Thank you very much for your reply. I have managed to work it as you mentioned I had to remove the "Runat server".
But Still I cannot display a SharePoint page on a Iframe.
I m tryng to do this
<li><a OnCLICK="document.getElementById('frame1').src = 'https://xxxx-my.sharepoint.com';" >Personal Address</a></li>

"To help protect the security of information you enter into this website, the publisher of this content does not allow it to be displayed in a frame"
I have added the following code to mysite.master page on the saharepoint , still now working . Any help please.
<%@ Register Tagprefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages" Assembly="Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Upload very large file to SharePoint Online

Hi,
I tried uploading very large files to SharePoint online via the REST API using JAVA. Uploading files with a size of ~160 mb works well, but if the filesize is between 400mb and 1,6 gb I either receive a Socket Exception (Connection reset by peer) or an error
of SharePoint telling me "the security validation for the page is invalid".
So first of all I want to ask you, how to work around the security validation error. As far as I understand the token, which I have added to my X-RequestDigest header of the http post request seems to be expired (by default it expires after 1800 seconds).
Uploading such large files is time consuming, so I can't change the token in my header while uploading the file. How can I extend the expiration time of the token (if it is possible)? Could it help to send post requests with the same token
continuously while uploading the file and therefore prevent the token from expiration? Is there any other strategy to upload such large files which need much more than 1800 seconds for upload?
Additionally any thoughts on the socket exception? It happens quite sporadically. So sometimes it happens after uploading 100 mb, and the other time I have already uploaded 1 gb.
Thanks in advance!

Hi,
Thanks for the reply, the reason I'm looking into this is so users can migrate there files to SharePoint online/Office 365. The max file limit is 2gb, so thought I would try and cover this.
I've looked into that link before, and when I try and use those end points ie StartUpload I get the following response
{"error":{"code":"-1, System.NotImplementedException","message":{"lang":"en-US","value":"The
method or operation is not implemented."}}}
I can only presume is that these endpoints have not been implemented yet, even though the documentation says they only available for Office 365 which is what I am using.
Also, the other strange thing is that I can actually upload a file of 512mb to the server as I can see it in the web UI. The problem I am experiencing is get a response, it hangs on this line until the TimeOut is reached.
WebResponse wresp = wreq.GetResponse();
I've tried flushing and closing the stream, sendchunked but still no success

Site collections, or sub-sites, in SharePoint Online?

We have an established SharePoint 2010 intranet portal, which has many and various team sub-sites. These sub-sites are created on request - sometimes it's because one of our locations wants their own little area to share documents, or it might be for
a company-wide project or initiative.
We are now slowly moving over to SharePoint Online. Mainly, it's to replace Box and Dropbox (which some teams use), and allow our staff to share files externally if needed. Nothing special, just a document library. More often than not,
each site will have its own unique permissions.
Now, our SharePoint 2010 site is one large site collection (wasn't my idea). As an administrator, that makes my life quite easy as it's one content database, one set of content types, etc. But, with SharePoint Online, I don't need to think about
content databases, and won't be using custom content types with these sites.
So, I'm a bit stuck. My options, as I see it, are:
One large site collection (pretty much a no-go as these shared files might get quite large)
One site collection for each request, no questions asked (which might lead to hundreds of site collections)
Create a site collection for each office location, and then a sub-site for each team in that location (as requested) - and also create a site collection for each company-wide function, and create a sub-site for each project within that function
Can anyone give any pointers towards the "best" option to use here?

it always depends on different things.
One of the key elements I always use to decide site vs site collection is security boundary.
If the target site has a high level of confidentional information, I prefer a dedicated Site collection.
If it is just a smaller team (or broader team) to share info with you can easy use sub sites.
Looking at the boundary & limits is also wise to do. (like the 5000 item treshold in a view on a document library)
A document library should in practice not really be used for multiple teams, however it is possible. A lot of dl's within a site is also not that intuitive for a lot of end-users.
A office location can be use, however, a lot of work is done across office locations. (now or in the future)
One site collection per each request is not by definition a bad thiing... however please be in control (governance) of the owners. For example let a site collection owner every x months acknowledge that he/she still needs that site collection or that it
can be removed.
One Large site collection is asking for trouble in the end. however for a publishing intranet only it can be good.
Good luck with your choice for your environment!

How to export SharePoint Online sites in an offline format that can be accessed without SharePoint?

Details:
Non-techie needs to archive SharePoint site and apps content into one convenient file.
1. Currently SharePoint calenders, contacts and tasks synced to Outlook and exported to an Outlook .pst;
2. Document libraries to a folder in file system;
3. SharePoint Online 2013 microfeed cannot sync at all (correct me if I'm wrong).
4. Pages also not really exportable.
Migration between O365 plans and tenants I can use .wsp but still limited to 50MB export and needs site collection settings access.
Ideally able to access these content offline (no security implications here).
Anyone know of a simple way?

Hi Tian-An,
SharePoint contents (e.g. document files, list items, pages) are stored in SQL database, it may if you want to use the contents without SharePoint environment, I think you can click "Open with Exporer" from library ribbon and then copy them to
the file system(e.g. a network dirve fileshare), note that the library columns value would be unable to be copied/exported; for the list items you can click "Export to Excel" button form list ribbon to export list itmes to
excel file, or as you have done with connecting to Outlook.
And we have a dedicated Office365 SharePoint online forum, I would recommand you post there for getting a better assistance redarding this SharePoint online contents exporting.
