Permission activesync on smartphone
Hi everyone, when you grant the permissions in question to manage company email from a smartphone, do these permissions, in addition to Remote Wipe, Password Enforcement and Device Encryption (I remember these as the main ones), somehow give the Exchange administrator access to my personal data? For example, photos, any documents saved on the SD card or on the smartphone itself? Thanks in advanced!High Volume Email is Generally Available and Ready to Charge
On April 1, Microsoft announced the general availability for the High-Volume Email (HVE) solution together with details of the PAYG charges incurred to send email to internal recipients, which is all that HVE can do. Microsoft will enable HVE charging on June 1, 2026, Before then, you’ll need to create a billing policy and link it to a valid Azure subscription if you want to continue to use HVE. https://office365itpros.com/2026/04/23/hve-ga-charging/Microsoft Limits App Access to Sensitive Message Properties
Microsoft has announced details of a change to app permissions to restrict updates to sensitive message properties (like recipients) without consent for a new advanced mail access permission. If tenants have apps that interact with message properties, including apps developed by third parties, they should check whether the apps are updating sensitive properties. If so, the new permission must be assigned or the apps will stop working. https://office365itpros.com/2026/03/26/sensitive-message-properties-graph/Can we hide default address lists in Outlook Address Book and show only custom ones?
There are existing Custom Address Lists. When users use the MS Outlook App (Office 2019) and open the Address Book, is it possible to hide the other address lists (including domain-sg-GAL, Global Address List, and domain-sg-Rooms), and only display the Custom Address Lists (domain-HK-AL and domain-sg-AL) — the ones shown in green in the photo?Microsoft Rushes High-Volume Email to General Availability
Almost two years after it first previewed, Microsoft is making the High-Volume Email (HVE) solution generally available in March 2026. HVE runs on a pay-as-you-go basis, but Microsoft won’t start charging tenants for sending email until May 2026. Two months should be enough for people to decide if they want to use HVE for internal communications as it has no ability to send external email. https://office365itpros.com/2026/03/09/hve-ga/Measuring KPIs like Response Times for Shared Mailboxes
Shared mailboxes are not CRM systems. However, many Microsoft 365 tenants use shared mailboxes to handle customer queries and then want to measure KPIs such as agent responsiveness to customer queries or the number of queries handled per agent in a month. As explored in this article, it’s possible to use the Microsoft Graph and PowerShell to extract some KPI-like data from shared mailboxes. https://office365itpros.com/2026/03/05/shared-mailbox-kpi/
Proper whitelisting of microsoft.com on dnswl.org
I keep having the issue that system-generated e-mails, e.g. on Trace Reports get classified as spam by the receiving e-mail provider. The sender address is email address removed for privacy reasons and the e-mails go to my M365 mailbox and are redirected to my external monitoring mailbox with that e-mail provider. The e-mail provider calculates a score that includes checking the sender's IP address 52.101.69.91 with dnswl.org . Unfortunately, that address is only whitelisted for outlook.com and some secondary domains, but not for microsoft.com. Of course, the issue also occurs with mailto:email address removed for privacy reasons and other IP addresses, so this is an example. It started to occur around two weeks ago, not sure if the provider changed policies or Microsoft changed the whitelisting; of course the provider refuses to overrun dnswl.org it, e.g. by own whitelisting. Who at Microsoft could I ask to fix that kind of issues? I don't find any appropriate category in their support menues, M365 support says the cannot help (TrackingID#2603031420001611). Thanks in advance for any hints, this is my first posting here, so please forgive me, if this is a dumb question.Exchange Online PowerShell Dumps the Credential Parameter
On February 12, Microsoft announced the deprecation of the Credential parameter for the Connect-ExchangeOnline cmdlet in the Exchange Online PowerShell module. The deprecation won’t affect interactive sessions (which should all be protected by MFA), but it might stop some background jobs running when Microsoft retires the server components that currently support the ROPC authentication flow. Time to check scripts! https://office365itpros.com/2026/02/16/exchange-online-powershell-ropc/
