Hello. While I was trying to sync Office 365 updates in my environment, I've found that it takes a really long time for it to sync. Looking into wsyncmgr.log, I've noticed that after " Synchronizing update df83ae97-3f19-4665-8d37-1e05157a3360 - Microsoft 365 Apps Update - Current Channel (Preview) Version 2105 for x64 based Edition (Build 14026.20138)", "Base Url for Office update file list service not configured or not valid , keep the original Url", and "Process O365 update manifest with no proxy.", the sync will get stuck for a few minutes before it moves on to the next update. But I can't seem to find the way I can configure the "Base url for Office update file list service". I believed that the sync will run much faster after I configure this url. Can anyone help me with the way to configure this "Base Url"? Thanks.

    Hi @CUCOOPE ,

    Thanks for posting in Microsoft Q&A forum.

    As you mentioned, it seems that the synchronization completed normally.
    So the issue "Base url for Office update file list service not configured or invalid" could just the warning instead of the error.

    The Microsoft 365 and Office 365 services are being improving and adding new features continuously, which means the required ports, URLs, and IP addresses will changed over time.
    This might be the cause of this issue.

    One of the requirements for using CM to manage Office updates is that:

    The hierarchy's top level WSUS server and the top level Configuration Manager site server must have access to the following URLs: .microsoft.com, .msocdn.com, .office.com, .office.net, .onmicrosoft.com, officecdn.microsoft.com, officecdn.microsoft.com.edgesuite.net.

    To get the detailed and up-to-date list of the URLs and other information, please refer to the following link:

    To learn how to properly configure Office 365 URLs and IP ranges, use this article as a reference:

    Hope the above information can help you.
