M365: Microsoft is changing the authentication process for external users who access content shared via OneDrive or SharePoint Online
AFFECTED
M365–Organisation: "KIT - Karlsruhe Institute for Technology" (=employees’ home organisation)
- SB: Microsoft OneDrive for Business - Tenant KIT0: "KIT - Karlsruhe Institute for Technology" (Heimatorganisation der Mitarbeitenden)
- SB: Microsoft SharePoint Online - Tenant KIT0: "KIT - Karlsruhe Institute for Technology" (Heimatorganisation der Mitarbeitenden)
REASON
Configuration change
DESCRIPTION
Microsoft is changing the authentication method external users use to access content shared through OneDrive and SharePoint Online.
The previous SharePoint Online One-Time Passcode (OTP) method will be retired and replaced by Microsoft Entra B2B authentication.
What is changing?
Previously, external users could access shared content by signing in with a SharePoint Online One-Time Passcode (OTP) sent to their email address. Microsoft is moving this process to Microsoft Entra B2B.
Timeline:
- Starting in July 2026, SharePoint Online One-Time Passcode (OTP) authentication will be gradually retired.
- The transition is expected to be completed by August 31, 2026.
- External users who already have a Microsoft Entra B2B guest account will not be affected by this change.
- External users who do not yet have a Microsoft Entra B2B guest account may no longer be able to access content that was previously shared with them after the retirement begins in July 2026. In this case, an access denied message may appear.
- To restore access, it is sufficient to re-share a file or folder with the affected user using the same email address. This creates the required guest account.
- If an external user uses multiple sharing links, re-sharing a single item is sufficient. After that, all previously shared links for this user will work again.
What do you need to do?
In most cases, no action is required. If an external user can no longer access shared content after July 2026, simply re-share a file or folder with the same external email address. After that, access to all previously shared content will be restored.
DESCRIPTION
The provision of data in BWP Reporting is being expanded.
As it is not possible to correct the initial delta load into BW retrospectively without deleting the cube contents, the delta initialisation from 000.2024 must be deleted and the reload repeated using a delta initialisation from 000.2020.
AFFECTED / IMPACT
SAP BW, reporting unavailable
The reporting function will not be available from Friday afternoon. From Monday, the reporting function will be available with the expanded data set.
CAUSE
Changes to the requirements for the provision of data in BWP reporting
With the go-live of KIT 2.0, in consultation with SE1, the delta initialisations in SAP BWP were set to ‘two years back’, as it was believed this would be sufficient because changes to older data do not occur. Subsequently, however, the Budget Department realised that changes to plan data for the years prior to 2024 were indeed necessary and that these were not being transferred to BW Reporting. Changes going back up to five years are expected here, both in the budget and in the actual figures.
