Veeam for Microsoft 365 What’s unsupported after the deprecation of basic authentication?

Share This Post

After Microsoft’s decision to deprecate basic authentication in favor of modern authentication, there are a few things that will change when switching from basic to modern. Below are items that are not supported through modern app-only authentication, and support that has been added in newer releases:

  • Discovery Search mailboxes (Added in 7.0.0.3968.)

  • Public Folder mailboxes. (alternatively, Microsoft recommends using Microsoft 365 Groups. Additionally 7.0.0.3968 added support for Public Folder mailboxes.)

  • Dynamic Distribution groups.

  • SharePoint Web Parts can only be backed up if their ‘exportmode’ property is enabled.

  • Web Parts by default (to backup Web Parts you must enable the “Allow custom script” option.)


Further information on what is/is not supported when switching to modern authentication can be found here KB3146. If you would like assistance, or have any further questions on what is supported, please email Support@Managecast.com.
