OneDrive for Mac Now Supports Removable Drives
Earlier this year, we announced support for several improvements to OneDrive for Mac, including support for external, non-removable drives. We’ve heard feedback about the differences between “non-removable” and removable drives, and wanting the flexibility to sync OneDrive to any external drive—no matter the type. Now, with OneDrive version 25.127 or later, you can seamlessly sync your OneDrive files to any external drive, including removable ones. Syncing to a removable drive works just like any other drive, except that if you unplug your drive, OneDrive will stop syncing and show an error. You’ll need to plug your drive back in and restart OneDrive to resume syncing. There’s a short grace period between when a drive gets disconnected and when OneDrive shows an error to handle drives that sporadically disconnect. There are a few requirements your system must meet to use this feature: You’ll need version 25.127 or later of OneDrive. You also need to be running macOS 15.0 or later. The drive you select must meet the following requirements: Formatted for APFS Protected by FileVault (see below for instructions) Not read-only, a network drive, or marked as quarantined by macOS. Just like before, you'll need to manually set up a new sync relationship on the new drive. Sync settings won't transfer automatically. You cannot use OneDrive by moving your external drive between Macs; you must set up OneDrive again on each new Mac with the external drive. To protect a drive with FileVault: Format the drive for case-insensitive APFS, if it is not already. Find the drive in the Finder. Option/right click the drive and choose Encrypt. Follow the prompts. That’s it! We’d love to hear your feedback about this change! The best way to do that is to click on the OneDrive icon in the macOS Menu bar (near the clock), click the gear icon, and choose Send Feedback. You can also leave a comment here. We read them all, even if we can’t reply to them all.
Changing to Always Keep... changes all folders
Within a folder on OneDrive,there are other folders and files. I want to have some just on the cloud, and always keep some on my computer. When I click on Always Keep On This Computer, all the other folders at that folder level also change to Always Keep On This Computer. I'm not talking about the contents of the folder (which I'd expect to change), I'm talking about the folders at the same level as the one I change. Also, I have a couple of folders and files that show the white checked status icon in windows explorer (as opposed to the solid green one). The right click list shows a check on those for Always Keep on this computer. Why don't they have the solid green status icon? They don't even change in the situation described above.Outlook for Mac - Upload and Share is not working as access "Recipients of this message" is missing
New Outlook for Mac has since some versions back gotten the feature where the user can upload a file and share it to the recipients of the e-mail. The file will be per default be uploaded to DOWNLOAD folder in OneDrive. Now this is not working on Outlook for Mac as the whole access permission Recipients of this message" is missing. On Windows and Outlook on Web, this is available, but not for New Outlook for Mac. It seems that this feature is not yet fully developed on Outlook for Mac. Any others that see the same and can confirm?External people can't open files with Sensitivity Label encryption.
Question: What are the best practices for ensuring external users can open files encrypted with Sensitivity Labels? Hi all. I've been investigating proper setup of sensitivity labels in Purview, and the impact on user experience. The prerequisites are simple enough, creating and configuring the labels reasonably straightforward, and publishing them is a breeze. But using them appears to be a different matter! Everything is fine for labels that don't apply encryption (control access) or when used internally. However, the problems come when labels do apply encryption and information is sent externally. The result is that we apply a label to a document, attach that document to an email, and send it externally - and the recipient says they can't open it and they get an error that their email address is not in our directory. This is because due to the encryption, the external user needs to authenticate back to our tenant, and if they're not in our tenant they obviously can't do this so the files won't open. So, back to the question above. What's the easiest / most secure / best way to add any user we might share encrypted content with to our tenant. As I see it we have the following options: Users have to request Admins add the user as a Guest in our tenant before they send the content. Let's face it, they'll not do this and/or get frustrated. Users share encrypted content directly from SharePoint / OneDrive, rather than attaching it to emails (as that would automatically add the external person as a Guest in the tenant). This will be fine in some circumstances, but won't always be appropriate (when you want to send them a point-in-time version of a doc). With good SharePoint setup, site Owners would also have to approve the share before it gets sent which could delay things. Admins add all possible domains that encrypted content might be shared with to Entra B2B Direct Connect (so the external recipient doesn't have to be our tenant). This may not be practical as you often don't know who you'll need to share with and we work with hundreds of organisations. The bigger gotcha is that the external organisation would also have to configure Entra B2B Direct Connect. Admins default Entra B2B Direct Connect to 'Allow All'. This opens up a significant attack surface and also still requires any external organisation to configure Entra B2B Direct Connect as well. I really want to make this work, but it need to be as simple as possible for the end users sharing sensitive or confidential content. And all of the above options seem to have significant down-sides. I'm really hoping someone who uses Sensitivity Labels on a day-to-day basis can provide some help or advice to share their experiences. Thanks, Oz.
Escalation Inquiry: IP Logs Request for MS Account
Hello, I am seeking advice regarding a security issue with my Microsoft account. There were unauthorized login attempts on my account between May 23 and May 25, 2025. I submitted a ticket to Microsoft Privacy / Security Incident Response (SIR) regarding IP activity logs. My ticket was created on August 7, 2025 and escalated to the IP/SIR team on August 11, 2025. Since then, I have sent multiple follow-ups, but no response has been received. I also created a new ticket on September 17, 2025, but only received the automatic acknowledgment; no agent has contacted me. I am concerned because the logs are important for verifying my account security and ensuring no unauthorized access occurred. Could anyone advise typical processing times for IP activity requests or suggest ways to escalate this issue effectively? Thank you in advance for any guidance.OneDrive for Business sync issues.
