Outlook 365: Folder sorting resets automatically to A–Z
Outlook 365 – Folder sorting resets automatically Environment: - Outlook desktop app (Microsoft 365) - Exchange / Office 365 mailbox - Dark mode enabled - Multiple shared mailboxes Problem description: Outlook automatically changes the folder sorting/display settings without user action. The option “Sort subfolders A to Z” reactivates randomly during the day. The configured sorting (e.g., Received – Descending) resets several times per day. In View Settings, the sorting remains configured correctly, but visually Outlook displays a different order. The issue occurs across multiple folders (Inbox, shared mailboxes). Actions already taken: - Verified and modified sorting via View > View Settings > Sort. - Applied the same view to multiple folders. - Confirmed that the settings remain saved correctly. - Issue persists: the parameter stays the same, but Outlook displays mails differently after refresh. Possible causes considered: 1. Outlook bug – display refresh resets the sorting visually even though settings remain unchanged. 2. Corrupted Outlook views – local view definition might be corrupted (outlook.exe /cleanviews). 3. Outlook add-in – third-party add-in may override sorting. 4. Exchange synchronization – server-side policy may enforce default sorting on shared mailboxes. 5. Recent Microsoft 365 updates – some users have reported similar issues in 2025 (views automatically resetting). Request: - Confirm whether this is a known Outlook 365 bug related to automatic resetting of folder views/sorting. - Provide solution or patch/workaround. - Official Microsoft recommendations to prevent Outlook from reverting to A → Z sorting automatically.
Outlook “Messages in This Conversation” Shows Unrelated Emails Despite Exact Match
Hi, I’m having an issue with Outlook’s “Messages in this Conversation” search. When I right‑click an email, say the subject is “Weekly Project Update”, and choose Find Related - Messages in this Conversation, I expect to see only emails with that same subject. I’ve even set the advanced search condition to Subject is (exactly). Despite that, I still get a mix of unrelated emails like “Re: Lunch Plans” or “Quick Question” appearing in the results. It feels like the search isn’t respecting the exact-match setting and is just grabbing anything loosely related. its Outlook 2016 Couldnt find any information about it online, any help would be appreciated, thanks.
Attachment issue in New Outlook
Hi, Some, but not all, PDF attachments cannot be opened from New Outlook. It seems to be related to the size of the PDF attachment - some of the large files cannot be opened anymore. The error message on opening is that the file is corrupted. From OWA Outlook, the attachment opens in Adobe Reader or in the browser, regardless of which one is used, so the file on the Exchange is not damaged. This issue started happening a few days ago, during August 2025. I contacted Adobe support and they are addressing the issue to the Microsoft. How do I fix the issue without reverting to classic Outlook or opening attachments from OWS Outlook? Also, downloading the attachment to my computer is not an option as it does not solve anything - the attachment file is still corrupt and this makes the workflow unnecessarily complicated. MirkoExploring Outlook Newsletter 2025: Tips, Feedback & What to Expect
I recently spent some time exploring the new Outlook Newsletter (Preview) feature, and I was pleasantly surprised by how intuitive and useful it is! If you haven’t seen it yet, it’s a new app available in New Outlook, Classic Outlook, and Outlook on the Web (OWA). It lets Microsoft 365 subscribers with a work or school account create and send clean, professional-looking newsletters—right from your inbox. No extra tools or design experience needed. It even has its dedicated site: https://outlook.office.com/newsletter. In my blog post, I share a few tips to help you get started, highlight some current limitations to be aware of, and include feedback I’ve already shared with Microsoft.

How to remove add-in in new Outlook
Hi, in old outlook I used https://aka.ms/olksideload to remove an Outlook add-in I'm developing. There is a big delay, but eventually the add-in is deactivated. In the new Outlook, this method still works. However, if I try to remove it using the menu provided in the new outlook client (apps>manage your apps>remove), it makes a request to https://teams.microsoft.com/api/apps/emea/beta/users/apps/entitlements/(id (followed by an ID string), and I get the response 403 forbidden. It is difficult for me because I am not an admin, but what can I suggest our admin check out to allow the app remove privilege to work in the new Outlook? Thanks.
Receive a recurrent email and only keep the latest one
Morning. I have a report that i receive via email every hour (in case there are updates that need to be uploaded to one of our systems) the emails are directed to a specific folder via a rule. But instead of having an accumulation of 24 emails a day, I would like to only keep the latest one and delete the others (and not having to do that manually ) Is there a rule or policy i can use for this? thanks
Some Events Not Syncing With All Apps
I cannot figure out what the issue is, but some events are not showing up in all my calendar apps: Outlook for Mac, Apple Calendar, Fantastical, Dato and Teams. I just added an event using Outlook, and it is not showing in Apple Calendar or Dato, but it shows in Fantastical, Outlook and Teams. I added one using Fantastical's menu bar and it didn't show in Outlook or Teams. There is no rhyme or reason; syncing is just not consistently working.
