Microsoft 365 Restore on AhsayOBM

March 26, 2026

Before performing the restoration, it is best to be knowledgeable about the options that AhsayOBM can offer. Below are brief descriptions of the said features for you to be familiar with and utilize each function. After this quick walkthrough, you will see the step-by-step instructions with corresponding screenshots on how to restore your data using the following options below.

For Microsoft 365, you can restore items from:

  • Users

    This is composed of data from Outlook, OneDrive, Personal Site, and Teams Chat.

  • Teams

    This is composed of data from Group Mail, Group Site, and Teams Channel.

  • SharePoint Sites

    This is composed of one Top-level site, List and Libraries and Subsites.

  • Public Folders

    This is composed of one Top-level site and Public Folders.

Those items can be restored to:

  • Original

    Restore your data to the original Microsoft 365 account.

  • Alternate

    Restore your data to an alternate location on the same Microsoft 365 domain. Alternate location depends on the source of the items. It can be from Users, Teams, SharePoint Sites or Public Folders.


    Example #1:

    Restore Items from Users

    Microsoft 365 Account: Test AccountABC@onecompany
    Alternate Users: TestUserAccount01@onecompany
    TestUserAccount02@onecompany
    TestUserAccount03@onecompany
    TestUserAccount04@onecompany
    TestUserAccount05@onecompany

    Explanation:

    For the example above, we have TestAccountABC@onecompany as our Microsoft 365 account. For the alternate user, a list will be available, and from there you can choose from the following Microsoft 365 accounts:

    • TestUserAccount01@onecompany
    • TestUserAccount02@onecompany
    • TestUserAccount03@onecompany
    • TestUserAccount04@onecompany
    • TestUserAccount05@onecompany

    Example #2:

    Restore Items from Teams

    Teams Group: SampleTeamsGroupAccountXYZ
    Alternate Groups: SampleTeamsGroup01
    SampleTeamsGroup02
    SampleTeamsGroup03
    SampleTeamsGroup04
    SampleTeamsGroup05

    Explanation:

    For the example above, we have SampleTeamsGroupAccountXYZ as our Teams group. For the alternate group, a list will be available, and from there you can choose from the following Teams group:

    • SampleTeamsGroup01
    • SampleTeamsGroup02
    • SampleTeamsGroup03
    • SampleTeamsGroup04
    • SampleTeamsGroup05

    Example #3:

    Restore Items from SharePoint Sites

    SharePoint Sites: blackbox.sharepoint.com/sites/OriginalSite
    Alternate Sites: blackbox.sharepoint.com/sites/NewSite1
    blackbox.sharepoint.com/sites/NewSite2
    blackbox.sharepoint.com/sites/NewSite3
    blackbox.sharepoint.com/sites/NewSite4
    blackbox.sharepoint.com/sites/NewSite5

    Explanation:

    For the example above, we have blackbox.sharepoint.com/sites/OriginalSite as our site. For the alternate site, a list will be available, and from there you can choose from the following SharePoint Sites:

    • blackbox.sharepoint.com/sites/NewSite1
    • blackbox.sharepoint.com/sites/NewSite2
    • blackbox.sharepoint.com/sites/NewSite3
    • blackbox.sharepoint.com/sites/NewSite4
    • blackbox.sharepoint.com/sites/NewSite5
  • Alternate Microsoft 365 organization

    You can restore your data to an alternate Microsoft 365 organization that has a different domain.

    Example:

    Original Microsoft 365 Account:     TestAccountABC@onecompany

    Alternate Microsoft 365 Account:   SampleAccountXYZ@twosquaretower

    Explanation:

    As you can see in the above example, we have two (2) Microsoft 365 accounts with different domains. The Original Microsoft 365 account is what we used as the source of our backup and can also use as the original location for restoration. For the alternate Microsoft 365 account, we need to use another Microsoft 365 account that has a different domain.

    • Local Computer

      Restore your data as an archive file to your local computer where AhsayOBM is running. Data will be exported in the following format:

      • MS Teams Chat/Channel will be exported as HTML
      • Emails will be exported as PST
      • SharePoint Sites will be exported as CSV
    • OneDrive of Original Microsoft 365 organization

      Restore your data as an archive file to the OneDrive of a user on the same Microsoft 365 domain. Data will be exported in the same format as in a local computer.

    • OneDrive of Alternate Microsoft 365 organization

      Restore your data as an archive file to the OneDrive of a user on a different Microsoft 365 domain. Data will be exported in the same format as in a local computer.
