Frage an die Administratoren von SharePoint Online und Exchange Online, ob es derzeit Störungen gibt, die bemerkt werden? Ein Blog-Leser hat mich per E-Mail informiert (danke dafür) und schrieb "Sowohl Sharepoint als auch Exchange Online machen Zicken". Microsoft hat das Ganze mit den Meldungen EX1188132 und SP1187718 mehr oder weniger bestätigt. Nachfolgend eine kurze Übersicht über die betreffenden Meldungen.

From our analysis into the service health telemetry errors and reports of impact from a subset of users, we suspect there may be a code issue within the affected service infrastructure that's contributing to the persistent impact. We're investigating further into this potential code issue to pinpoint what's causing the behavior and to identify a solution that addresses the remaining impact.

Hallo,
mehrere Mitarbeiter berichten, dass sie bestimmte Bibliotheken erst nach mehrmaligem Öffnen aufrufen können. Zwischendurch kommt es immer wieder vor, dass die Zielseite nicht geladen wird.
Liebe Grüße!
SP1187718:
Benutzerauswirkungen
Users may be unable to load pages with custom apps or webparts in SharePoint Online and get an error.
More info
The following error may be encountered by users when attempting to load an affected page:
An error occurred during the compilation of the requested file, or one of its dependencies. 'Microsoft.SharePoint.IdentityModel.SPAuthFlightController' does not contain a definition for 'IsRemoveRedirectWithProofTokenOnSignInPageEnabled'
Scope of impact
Some users may be unable to load pages with custom apps or webparts in SharePoint Online and get an error. This section may be updated as our investigation continues.
Root cause
A recent change intended to update the authentication flow has mistakenly removed a necessary authentication component, resulting in impact.
Updates:
The deployment of the fix is nearing completion, and we've confirmed that some affected users are already experiencing impact resolution. We'll continue monitoring the deployment to ensure the issue is fully resolved for all affected users by our next scheduled update.
Hier keine Probleme festzustellen (EXO)
Hier ebenfalls einzelne User betroffen (EXO).
Leider immer wieder, dass einzelne Funktionen nicht funktionieren. Noch am gleichen Tag funktioniert es meistens wieder.
SharePoint Online macht bei uns gelegentlich Probleme beim Sync einzelner Ordner in das OneDrive.
Ebenfalls macht uns der Sync von Exchange Online Postfächern gelegentlich fertig. Keine Ahnung was MS da mit Ihren Produkten macht.
