The sign-in name or password does not match one...

I am creating a C# Solution that will migrate the documents from SharePoint 2010 On-Premises to SharePoint Online.

I am done with the program. But when I run the program it runs successfully for few times. After some time it starts throwing error:

Microsoft.SharePoint.Client.IdcrlException: The sign-in name or password does not match one in the Microsoft account system.

I am unable to track the actual error.

Here I am sharing my code:

public void CreateFolderStructures(MigrationFolders migrationFolders)
{
using (ClientContext clientContext = new ClientContext("Site URL")
{
string SPOnlineUsername = "Username";
string SPOnlinePassword = "PASSWORD";
foreach (char c in SPOnlinePassword)
{
securePassword.AppendChar(c);
}
clientContext.Credentials = new SharePointOnlineCredentials(SPOnlineUsername, securePassword);
var list = clientContext.Web.Lists.GetByTitle(DocumentLibraryName);
ListItemCreationInformation newItemInfo = new ListItemCreationInformation();
newItemInfo.UnderlyingObjectType = FileSystemObjectType.Folder;
newItemInfo.LeafName = migrationFolders.FolderName;
newItemInfo.FolderUrl = "SITEURL" + migrationFolders.FolderPath;
ListItem newListItem = list.AddItem(newItemInfo);
newListItem.Update();
list.Update();
clientContext.ExecuteQuery();
newListItem["Modified"] = migrationFolders.ModifiedDDate;
newListItem["Created"] = migrationFolders.CreatedDate;
newListItem.Update();
list.Update();
clientContext.ExecuteQuery();
}
}

The above code is called in foreach loop.

I have gone through following URL but that is not the case with me.

Any suggestion how to resolve this error?

The problem was strange.

I was having a class that was resposible for managing Authentication and returning clientContext object. I The object of this class was created in the loop.

I changed the code and removed the class and its object creations from loop to outside and it worked.

This will not be always a solution but this was happend in my case.

SharePointOnlineCredentials --> This will access only onmicrosoft account.

That is the account name which should be in the form of [email protected].

It will not work if you are sending with account name in the pattern: [email protected] if the multi-factor authentication is enabled.

And the error message is as same as the one if you passed account name in the latter pattern which mentioned above.

Hi Aakash,

Your code is looking good. I am not sure what is the cause. But I am suggesting another way to migrate your documents from SP2010 to Online. Download your files and keep it in your local. Then follow the steps mentioned in the below link.

@Aakash - Apologies for that. When you are sure that your credentials are correct, i assume you are getting throttled out. In SharePoint online, you do have a user level throttling. I would ask you to verify if it is a throttling issue. You can try decorating your traffic. Check out my post at below link https://www.c-sharpcorner.com/article/what-is-traffic-decoration-and-how-you-can-use-it-to-best-avoid-throttling-in-sh/ If you notice a difference in the number of documents/time it takes to error out, with and without traffic decoration, then u are getting throttled. So u need to find other way round, like the azure migration way. What is the data size you are expecting to migrate??

@Chanakya Jayabalan,, thanks for your reply but I hope you know that SharePoint Migration tool only work with SharePoint 2013 On Premise version to SharePoint Online. While I have to move the document from SharePoint 2010.

Did you try the microsoft migration tool?

No, I have created the fresh library at SharePoint Online.
Nanddeep Nachan8y ago
Does it throws the error only if number of items are larger (close to threshold)?
Aakash Maurya8y ago
I have used "Using" so that everytime I get fresh new context. I even tried by managing context globally. I am using latest CSOM ONLINE libraries.
Nanddeep Nachan8y ago
May be a vague suggestion, but can we try by creating a fresh new clientContext in foreach loop?
Aakash Maurya8y ago
I even tried with declaring the clientcontext globally in the program but still no luck.

Hi Nanddeep Nachan,

Tried but with No luck. Getting the same error again and again.

Please try
clientContext.RequestTimeout = -1;
