  • 1.  Office 365 monthly patches - Size is around several GB

    Posted Jan 22, 2026 07:34 AM
    Hello Altiris community,
    I have a question for you and it is regarding Office 365 monthly patches. I would like to know how it is managed in your respective companies, because in our case it is causing lots of headaches from the beginning.
    The problem is the size of the packages, taking every month Altiris dowloads packages around 20GB. 
    We have read that the MS 365 uses a C2R technology so the size could vary from a few MB to several GB. Everything depends on how we are receiving the patch and the update channel. Altiris should download the incremental package but in our case it is always downloading the full package with all languages.
    Do you know if there is any way to improve /customize the management of this kind of MS 365 patches?
    How are you dealing with it in your company?
    Thanks a lot in advance for your help.

    to clarify the implementation details there - Altiris Patch Agent integrates with C2R technology to transfer only the bits of Office 365 required to update but it applies to Site Server to Agent (or Agent to Agent if P2P functionality is utilized) communication, not to staging of Office 365 image from Microsoft CDN to Notification Server. C2R allows to identify the binary differences between Office 365 installation on specific endpoint and new Office 365 image, not between two different Office 365 images.
    When referencing all languages being downloaded do you mean all languages selected in Patch Data Import task, not all languages available from Microsoft for this version of Office 365, right?
