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.
Accessing External Sharepoint Site
I am able to access internal Sharepoints within my company and have up until now been able to access Sharepoints outside the company. When I now try to access an external Sharepoint, I get the following message on the external company's landing page. "Your account has been locked. Contact your support person to unlock it, then try again...." The external company states they have not made changes any access protocols. Likewise, my company says nothing has changed with respect to the rules/ability to access external Sharepoints. Someone indicated that the Microsoft “federation” settings/setup of the two companies may (now) be incompatible. Has anyone encountered this issue?
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?Cross Tenant Migration licensing
Hello, I'm planning a native cross-tenant migration for several shared mailboxes that have archives enabled. I’m looking to confirm if it is necessary to temporarily convert these to user mailboxes in the source to ensure the archive data migrates successfully. Also, what specific licenses should I assign to the target objects specifically, do I need to provide an Exchange Online Plan 2 plus the Cross-Tenant User Data Migration add-on for each shared mailbox? If anyone has handled archived shared mailboxes recently, I’d appreciate a quick confirmation on the cleanest licensing and conversion steps. Thank you in advance ! :)
OneDrive for macOS documentation issue. DefaultFolder plist example is missing array wrapper
Hi everyone, The Microsoft Learn documentation for configuring the OneDrive sync app on macOS currently contains an incorrect plist example for the DefaultFolderLocation setting. Documentation page: https://learn.microsoft.com/en-us/sharepoint/deploy-and-configure-on-macos#defaultfolderlocation In the “DefaultFolderLocation” section, the current plist example shows the DefaultFolder key as a dictionary: <key>DefaultFolder</key> <dict> <key>Path</key> <string>(DefaultFolderPath)</string> <key>TenantId</key> <string>(TenantID)</string> </dict> This format does not work correctly when deployed as a managed preference/configuration profile. The setting starts working when the DefaultFolder dictionary is wrapped in an array, like this: <key>DefaultFolder</key> <array> <dict> <key>Path</key> <string>(DefaultFolderPath)</string> <key>TenantId</key> <string>(TenantID)</string> </dict> </array> Please update the Microsoft Learn documentation to include the array wrapper in the DefaultFolder plist example. The current Microsoft Learn example is confusing because administrators may deploy the documented plist exactly as shown, but the setting does not appear to work correctly until the array wrapper is added.Make Your Test Data Less Boring with M365Mutator
Testing Microsoft 365 scenarios often involves test data. If the data is stale or always the same, it might not generate good results or help to identify lurking problems. The M365Mutator app helps to solve the problem by mixing things up in your test data. The app can change properties of Entra ID accounts, send email, update calendars, and generally make sure that whatever you’re testing has fresh information to run against. https://office365itpros.com/2026/07/10/m365mutator-test-data/Make Your Test Data Less Boring with M365Mutator

We had a colleague leave who had their work email address and account connected to MANY Power Automate flows, SharePoint, OneDrive, Forms, Excel, etc. We are looking to create a recommendation / best practices for a single account that will be used by the I.T. department for use in Power Automate, etc. We will have colleagues in the I.T. department have access to SharePoint sites (maybe a security issue? do we EACH get our OWN accounts then?) and Power Automate We'd have to have it setup as an email enabled account so we'd have to pay instead of a service account. Other thoughts?
