Use an OWA Mailbox Policy to Block Attachment Download for the New Outlook for Windows
The ConditionalAccessPolicy setting in an OWA mailbox policy can be configured to work with Entra ID conditional access so that OWA blocks access to attachments on unmanaged devices. Microsoft originally introduced the feature in 2018 and as it turns out, the combination of OWA mailbox policy and CA policy also blocks attachment access for the new Outlook for Windows client.

The Downside of Losing the Exchange Mailbox Audit Search Cmdlets
Microsoft recently announced the deprecation of the Exchange cmdlets to search for mailbox audit data. The audit data is ingested into the Microsoft 365 unified audit log, but it’s more difficult to find and retrieve Exchange mailbox audit events. Methods are available to find mailbox audit data, but interpreting what comes back is different. Any script that depends on the old cmdlets must be updated to interact with the unified audit log.

Microsoft Introduces Control for Direct Send in Exchange Online
The Direct Send feature allows apps and devices to send unauthenticated email via Exchange Online to internal receipts. Microsoft doesn’t want unauthenticated connections to send email because these connections could be hijacked by spammers. Enter the Reject Send feature to block Direct Send. Reject Send is in preview now but Microsoft wants it to be the default setting in the future.

How to Find Active EWS-Based Apps in a Microsoft 365 Tenant
Microsoft will retire Exchange Web Services (EWS) from Exchange Online on October 1, 2026. A new usage report helps tenants understand what apps use EWS. Many of the apps are likely to be first-party (Microsoft) apps, but some might be third-party apps developed externally or internally. Those apps need to be retired or upgraded to use Graph APIs. Time is slipping away to do the work.

Ich kann ja verstehen, dass #domainfactory die eigene Infrastruktur schmal halten möchte, aber alle Kunden zu #Microsoft #ExchangeOnline zu migrieren ist schon schräg.
Wie bekomme ich denn nun meine #TYPO3 Installationen umgezogen?
Das kostet mich doch nur wieder unnötig Zeit und Nerven.
Hat #Hetzner da jemanden der hilft?

Exchange Online Restricts the Number of Dynamic Distribution Groups
Exchange Online is imposing a new tenant-wide limit of 3,000 Dynamic Distribution Groups. Few tenants might be affected, but the question might be asked why Microsoft is limiting DDGs at this point. Is it a cunning plan to prompt people to use dynamic Microsoft 365 groups instead? Or are some tenants abusing DDGs in weird and wonderful ways? Who knows, but the limit applies from early April 2025.

Using iOS Build Numbers in Exchange ActiveSync Device Access Rules
A change made in late 2024 allows Microsoft 365 tenants to use IOS build numbers in Exchange ActiveSync device access rules. Apparently, the idea is that tenants can insist that people use iOS devices with very specific build numbers (like iOS 18.3.1 22D72) before the devices can synchronize with Exchange Online mailboxes. You never know when you might need the feature (or so they say).
