Microsoft links Classic Outlook issue to email delivery problems Microsoft is investigating a known issue that prevents some Classic Outlook users from sending emails via Outlook.com, causing non-delivery reports and a permissions error (0x80070005-0x0004dc-0x000524). Microsoft recommends temporary mitigations—removing the M365 Address Book, hiding the Outlook.com contact from the tenant GAL, creating a new Classic Outlook profile, or using New Outlook/Outlook on the web—while it continues to investigate. #ClassicOutlook #ExchangeOnline

Priority Cleanup V2 : la purge intelligente des boîtes aux lettres Exchange, enfin digne de ce nom Il existe dans toute organisation une tension fondamentale, souvent inconfortable, entre deux impératifs contradictoires : conserver les données pour satisfaire les obligations légales et réglementaires, et pouvoir les supprimer définitivement quand les circonstances l'exigent. Exchange Online et Microsoft Purview ont longtemps excellé dans le premier exercice. Pour le second, les administrateurs devaient jusqu'ici naviguer à vue dans un labyrinthe procédural peu documenté et franchement risqué.

Microsoft Purview Priority Cleanup V2 va changer la façon dont les admins purgent les boîtes Exchange — plus rapide, plus traçable, enfin opérationnel.
