Microsoft Office 365 GCC High



On This Page

Overview

DryvIQ supports connections to Microsoft Office 365 Government Community Cloud (GCC) High--an environment that provides compliance with US government requirements for cloud services platforms. Connections can be made using an administrator account with the proper privileges to manage configurations. DryvIQ creates this connection using the OAuth 2.0 flow to simplify login and connection management.

Do not select the “Microsoft Office 365 GccH (OAuth 2.0 Deprecated)” connector. This is the old connector that uses CSOM, which Microsoft is deprecating. Select the “Microsoft Office 365 GccH” connector when creating the connection since it uses Microsoft Graph API, which results in better job performance.

Create Connection | User Interface

  1. Select Connections > Add connection.

  2. Select Microsoft Office 365 GccH as the platform on the Add connection modal.

  3. Enter the connection information. Reference the table below for details about each field.

  4. Select Sign in with Microsoft Office 365 GccH.

  5. Enter the email for the account being used to create the connection and click Next. You must use an admin account with the proper privileges to manage Microsoft 365 configurations.

  6. Enter the password for the account and select Sign in.

  7. You will see a "Connection test succeeded" message on the Add connection modal. (If you don't see this message, repeat the sign in and authorization steps above.)

  8. Select Done to finish creating the connection.

Field

Description

Required

Display as

Enter the display name for the connection. If you will be creating multiple connections, ensure the name readily identifies the connection. The name displays in the application, and you can use it to search for the connection and filter lists.

If you do not add a display name, the connection will automatically be named.

Optional 

URL

Enter the URL of your Microsoft 365 GCCH High account. 

You can find the URL by logging into Microsoft 365 GCCH High using the account you want to use to create the connection. The URL in the address bar is the URL you need to use.

Required

Token endpoint

This setting is rare for most Microsoft connections and can be left blank. If needed, this value will be provided by your administrator.

Optional

Graph API endpoint

This setting is rare for most Microsoft connections and can be left blank. If needed, this value will be provided by your administrator.

Optional

External users notifications

This indicates if you want to send notifications to external users. The default value is No, so no notifications will be sent. 

If you select Yes, notifications will be sent to external users when they have been granted access to content based on permissions.

Optional

Behavior When Deleting Items

Select the type of delete DryvIQ should perform when deleting items: Permanent or Soft. Soft delete is the default delete behavior; however, Permanent is the recommended behavior.

A soft delete marks items as a deleted. You can still access them to restore or permanently delete the items.

A permanent delete removes the items. This delete is not reversible.

Optional

Features and Limitations 

Platforms all have unique features and limitations. DryvIQ’s transfer engine manages these differences between platforms and allows you to configure actions based on Job Policies and Behaviors. Utilize the Platform Comparison tool to see how your integration platforms may interact regarding features and limitations.

Connection Pooling

Microsoft Office 365 connections using OAuth 2 authentication may experience bandwidth throttling from Microsoft when using connection pooling.

Delta Job Runs

After the initial transfer of an item using a Microsoft SharePoint connection, DryvIQ will leverage Microsoft’s change tracking API on delta job runs to identify changes. This results in fewer Graph API requests and shorter job execution times.

HTML Files

SharePoint online does not support uploading HTML files larger than 256 MB. If your migration includes HTML files that exceed this limit, the file transfer will fail, and an entry will be logged in the audit with the following message: "Unable to interpret the contents of this page because it exceeds the maximum page size of 268435456 bytes.”

Impersonation with Batch Mode

When using Impersonation with Batch Mode, SharePoint Online shows “System Account” in the activity rather than the impersonated user. This is expected behavior for batch mode/bulk migration API. With batch mode off, the impersonated user will display in the activity panel.

Invalid Characters and Spaces

DryvIQ verifies file and folder names to identify unsupported characters based on the platform. It then replaces invalid characters with an underscore (_) so the files and folders can be transferred. 

The logic includes leading and trailing spaces in file and folder names. DryvIQ replaces the space rather than trimming it because trimming the space could cause duplicate file names. Adding the underscore ensures the name remains unique.

DryvIQ will sanitize file names that contain combined Unicode characters by replacing the characters with an underscore (_).

Mapping

When creating CSV mapping files for import, the usernames must be lowercase to properly adhere to the search requirements for the connector.

Metadata Mapping

If a library requires specific metadata but the metadata is missing from a file being copied into the library, the file will be flagged and will not transfer on subsequent jobs runs. If you have files stuck in a flagged state due to missing metadata, you may need to manually transfer the files and add the required metadata.  

Timestamps

There is a discrepancy in timestamps for the SharePoint Online Folder Created Date when using CSOM and Batch ModeThis behavior is a known issue within OneDrive for Business/Office 365.

DryvIQ will attempt to preserve timestamps on folders when using both CSOM and the batch API. However, SharePoint Online updates the folder's modified dates whenever a file is uploaded into it. As a result, when using CSOM, the timestamps will be preserved when the folder is initially created but then updated after every file that gets uploaded. When using batch API, it preserves the timestamps on the folders after all of the files within the batch are committed. This is the cause for the discrepancy between the two methods.

Version Deletes

Version deletes are supported. 

Corrupt Files

If you see “Error=Value=CobaltAllZerosDetected” errors in the logs, the file that triggered the error will not be uploaded to SharePoint online. Microsoft produces this error for files it considers to be corrupt.


Transfer Content to SharePoint Online Shared Document Library | Connection URI and Path Example

  • PlatformType in Connection: office365

  • URI Pattern in Connection: https://company.sharepoint.com/[SiteNameWhereLibraryExists]/

  • Target/Path in Job: Connection Config: /[LibraryName]

This configuration will transfer data to the destination at the library specified. Connection will take it down to Site specific level. 

Path in the 'Job:Connection:Target' should be the Document Library.

Use the Library name found in the URI (you do not have to escape/encode spaces, just enter a space if that exists in the library name).

If a path is not specified, files will transfer to the default library for the site specified.


Create Connection | REST API

You will need to add the relevant connection information into the GET request. The following GET will return a Microsoft login link. Use the link to complete logging into the account and to grant DryvIQ access to the account. 

GET {{url}}v1/connections/platforms/office365-oauth2-gcch/new?domain={{YOUR URL}}&name={{YOUR CONNECTION NAME}}&client_id={{YOUR CLIENT ID}}&client_secret={{YOUR CLIENT SECRET}}

Create Job | Impersonation with Admin Connection

As a Office 365 administrator, you can impersonate a user using the path that relates to their content. Then, use their information in the impersonate_as block. (See Impersonation for more information on how to impersonate users.)
