Hello kirsty allan,
Thank you for reaching out to the Q&A forum. I can see how this would be very frustrating for your requested emails being routed to the Junk folder and the challenges with the 30-day automatic deletion policy.
You raise excellent questions about why your control over your own inbox has changed. I want to shed some light on why the system works this way now, and provide the best alternatives to help you manage this moving forward.
To briefly explain why your control over the inbox has changed: Outlook now relies heavily on global, server-side filtering to protect users from the high volume of phishing and malware. Because these security checks happen on the servers before the mail even reaches your local inbox, marking an item as "Not Junk" doesn't always override the global filter permanently.
Since there isn't currently a way to extend the 30-day deletion window or fully disable the filter, a good habit is to briefly check your Junk folder periodically. When you find something you need, actively add that email address or domain to your Safe Senders list. This is generally one of the most effective ways to tell the server to let those specific contacts bypass the spam filter entirely.
If you find that your Safe Senders list is not being respected, or the volume of legitimate mail going to junk is unusually high, I highly recommend directly contacting Microsoft customer support. They can look at your specific account routing and offer a more tailored resolution. Your experience is valued, and support can take a closer look at these ongoing routing concerns:
- Visit the Contact - Microsoft Support website.
- Type "Junk email filter" in the search box.
- Click Get Help, scroll to the bottom, and select Contact Support.
- Note: You will be asked to sign in to your personal Microsoft account.
- Under Products & Services, select Other Products.
- Under Category, select Microsoft 365 & Office.
- Click Confirm.
- Select Chat with a support agent in your web browser.
Additionally, I encourage you to provide your feedback via the Feedback Hub. Microsoft is actively listening to users, and the more users request a change—like extending the 30-day limit or having more manual control over the filter—the more likely it is to happen. If you decide to write a request there, please feel free to come back and share the link with us! That way, myself and other users in the forum can upvote it.
I hope this explanation helps explain what has transpired with your account. Please let me know if you need any further assistance!
