New Outlook: "Changing the ImapRemoteServerInfo is not allowed" after host migration
Hi everyone! I've migrated my domain/mailbox from one IMAP host to another in May. It cannot be added to New Outlook for Windows — fails instantly with INVALID_CREDENTIALS INTERACTION_REQUIRED, even when I deliberately enter a wrong password (so it's failing before authentication is even attempted). Using DevTools (olk.exe -devtools), the Network tab shows the real rejection from Microsoft's backend: Changing the ImapRemoteServerInfo is not allowed. Attempted to change it from imap.olddomain.sk to imap.newdomain.sk So New Outlook has a cloud-mailbox / connected-account shadow record for this address, pinned to the old host from a previous add attempt, and the backend refuses to update it. What I've confirmed: Webmail and a second mailbox on the same domain/host both work fine → not credentials, not the host. The account does not appear in Settings → Accounts (so I can't use "Remove from all devices" which worked on my first account). It's on no other device or client. App reset didn't help (record is server-side, not local). It's been ~7 weeks, so any 30-day inactivity purge hasn't cleared it How do I get this stuck cloud-mailbox / connected-account record purged when it isn't attached to any removable account? Is there a way to force it, or does this need Microsoft backend action?
Not receiving emails
Hi For 2 months I have been receiving progressively fewer emails. I have been through all the steps suggested (checking storage, rules, forwarding etc), and all these are OK. It's strange because some emails still get through, generally those from a private individual. The ones from big companies that I would normally receive eg phone supplier, utilities companies and reputable online retailers order confirmations or verification codes are not getting through. I've tried Microsoft support as I think it's a problem with their server for some reason blocking these emails, even though I've added them to my safe list, but they haven't been able to help. They keep sending me to the sender team, which tell me to go back to the other team! I'm fairly sure it's not a problem with the senders side, as there are so many different companies affected, the common denominator is my email account as the problem. Any ideas of a way I can fix this myself? Thanks15 productivity features in the new Outlook for Windows
Hello, Outlook community. I’m Vicki Milton, a Principal Product Manager on the Outlook team. Over the last year, we’ve added important capabilities across areas such as offline support, shared mailboxes, and PST files. Alongside those milestones, we've continued to deliver smaller improvements that help people work more efficiently throughout the day. This article highlights 15 productivity features in the new Outlook for Windows that can help you stay organized, reduce routine effort, and keep important work moving. Mail features Email remains central to how many people manage communications, priorities, and follow-up. Outlook includes familiar tools for composing and organizing messages, along with newer capabilities that can help reduce friction and make inbox management more efficient. Pin a mail: Keep important messages easy to find. The Pin feature keeps a selected email at the top of your inbox so it remains visible as new messages arrive. This can be useful for items you need to reference often or do not want to lose track of, such as travel details, approvals, or active requests. By keeping priority messages in view, Pin can reduce time spent searching and help you stay focused on current work. Snooze a mail: Return messages when they are relevant again. Snooze lets you temporarily remove an email from your inbox and have it reappear at a time you choose. This can help keep your inbox focused on messages you can act on now while ensuring follow-up items come back when they are timely. It is particularly useful for requests that depend on additional information, scheduled tasks, or work you plan to handle during dedicated focus time. Add multiple categories at the same time: Organize messages with fewer steps. If you use categories to manage incoming mail, Outlook makes it possible to apply more than one category in a single action. This can help when you need to capture multiple types of context, such as project, priority, or follow-up status, without reopening menus repeatedly. It is especially useful when processing a large number of messages. Sweep: Reduce repetitive inbox cleanup. Sweep lets you create automatic actions for messages from a specific sender. For example, you can delete promotional mail after a set period, keep only the latest message in a thread, or move recurring updates to a folder. This can help reduce manual cleanup and keep your inbox more focused on items that need attention. Schedule Send: Write on your schedule and deliver at the right time. Schedule Send lets you prepare messages when it is convenient for you and send them later at a time that works better for the recipient. This can improve visibility, support more intentional communication, and reduce the need to rely on reminders or leave messages in Drafts. Simplified folder sharing: Share folders more simply. Sharing a mail folder has traditionally required extra permission steps, especially for nested folders. Now, when you share a folder, Outlook can automatically apply the visibility permissions needed for its parent folders. This can reduce setup effort, help avoid access issues for recipients, and make folder sharing easier to complete with confidence. Calendar and meeting features For many people, the workday is shaped by meetings, schedule changes, and the need to stay aligned on what comes next. Outlook includes calendar and meeting capabilities that can help simplify planning, reduce coordination overhead, and make follow-up easier. Follow a meeting: Stay informed without attending live. The Follow RSVP option lets you indicate that you will not attend a meeting but still want access to the recap. This can be helpful when schedules overlap or when a meeting is useful to monitor without joining in real time. It can help you stay connected to outcomes and shared materials while keeping your calendar more manageable. Save calendar views: Return to the calendar setup you need more quickly. Saved Views let you store specific calendar combinations and switch back to them without rebuilding the same view each time. This can save time for people who move frequently between personal, team, and project schedules. It also can make it easier to review the right set of calendars for different planning tasks. Improved meeting tracking: Work with meeting responses more efficiently. Outlook includes tools that make it easier for organizers to review and manage meeting responses. You can sort attendee lists, search for names in the Tracking view, and copy or download response details when needed. These capabilities can be especially useful for larger meetings where attendance information needs to be reviewed quickly. Meeting recap: Find follow-up materials in one place. After a Teams meeting, the calendar event in Outlook can surface a Meeting recap with links to the recording, transcript, and shared files. This can make it easier to review what was discussed, confirm details, or catch up afterward. By keeping these materials together, Meeting recap can reduce the time it takes to get oriented after a meeting. Filtered views: Reduce visual clutter in your calendar. Filters let you hide meetings you are not attending and limit the distraction of declined or informational events. This can make it easier to scan your schedule, identify conflicts, and focus on the meetings that need your attention. For people with full calendars, it can help make planning more straightforward. Change a recurring event: Update future meetings while preserving earlier ones. When plans change, Outlook lets you edit the current event and all following events in a recurring series. This can make it easier to adjust details such as time, location, or agenda going forward without changing the record of past meetings. It can simplify updates for organizers and reduce disruption for attendees. Personalization and settings Settings can play a practical role in day-to-day productivity. A few adjustments can make it easier to focus, move between accounts and calendars, and work in a way that fits your preferences. Here are several settings-related features that can help make Outlook feel more streamlined and manageable. Rename your email accounts: Make the right inbox easier to recognize. If you use multiple accounts in Outlook, you can assign each one a custom name. This can help you tell accounts apart more quickly, reduce the chance of sending from the wrong inbox, and make navigation simpler as you move between accounts during the day. Modern themes: Choose a look that supports comfort and clarity. Outlook includes theme and color options that let you tailor the experience to your preferences. Visual settings can influence readability and comfort, especially for people who spend much of the day in email and calendar. Options such as Dark Mode and color customization can help make the interface feel easier to use over time. Keyboard shortcuts: Keep familiar ways of working. In Outlook, you can choose the shortcut style you prefer in Settings. This can help you maintain existing habits, reduce adjustment time, and complete common tasks with fewer steps. For people moving from classic Outlook or Outlook on the web, shortcut flexibility can make the transition more consistent. These features reflect a broader effort to help people work more efficiently in the new Outlook for Windows. Whether you are managing a high volume of email, coordinating a full calendar, or tailoring the experience to match your workflow, these updates are designed to reduce effort and improve day-to-day productivity.

Outlook Not Able to Open Files in Desktop App
Hello all, I work in an enterprise environment, and I have now seen two occurances of this issue. Essentially, when a user receives an email in New Outlook with a direct attach file (Word, Excel, PDF in Acrobat, etc.), and they try to open them in the desktop app, it simply never opens. No error codes or anything, essentially just "it did not work, restart Outlook" if anything at all. Opening in the web apps works fine, opening them from Outlook (Classic) in the desktop app works fine, and downloading them directly allows them to be opened as well. I did some searching for this, and found some issues from 2023 that seemed similar, but none of that troubleshooting got anywhere. From everything I can see, it seems like a bad update, but I cannot say for sure. Has anybody seen this, or any ideas on a way to fix this?
New Outlook - PST file cannot reopen and PST search not working
Hi, Issue 1 – One PST file cannot be reopened I have two PST files, PST A and PST B. PST A can currently be opened and browsed normally in New Outlook. PST B was previously opened in New Outlook and I was able to browse the folders and emails. However, after I closed/removed PST B from New Outlook, I am now unable to open/add the same PST file again. The PST file can still be opened using Classic Outlook. If the PST format is unsupported or too old for New Outlook, why was New Outlook able to open and browse it previously before I closed it? Could this be related to the PST format (ANSI vs Unicode), PST corruption, or a limitation/bug in New Outlook? Issue 2 – Unable to search emails stored in PST For PST A, I can open the PST and manually browse and read the emails in New Outlook. However, when I use Search, emails stored inside the PST do not appear in the search results. This is referring to searching for the email/message itself, not searching for attachments. The same PST can be searched using Classic Outlook. My understanding is that New Outlook now supports searching emails stored in PST files. Is PST search fully supported, or are there still limitations compared with Classic Outlook? I would appreciate any advice on how to troubleshoot both issues, especially whether there is a way to verify PST compatibility with New Outlook.
Outlook.com Spam Filtering Regression — Missing Rule Conditions Prevent Safe User‑Level Mitigation
I’m a program manager working with data engineers in a large corporation, and I’ve used Microsoft Exchange professionally for over 30 years. I’m posting because Outlook.com’s spam filtering pipeline appears to have regressed significantly, and the current rule system no longer provides the necessary conditions for users to mitigate the issue themselves. Summary of the Issue Over the past several months, Outlook.com has begun allowing large volumes of spam across multiple categories — explicit content, romance scams, foreign‑language marketing, calendar spam, health spam, lotto scams, and unsolicited newsletters. This is not typical spam leakage; it suggests a failure or degradation in one or more layers of the filtering pipeline (content classification, sender reputation scoring, behavioral heuristics, or transport‑level filtering). Technical Problem Outlook.com previously offered rule conditions that allowed users to safely filter spam based on message behavior and metadata. These included: Message type (new vs. reply) Does not include (critical for safe filtering) Header includes Unsubscribe detection Cold sender / no prior conversation These conditions are no longer available in the current Outlook.com rule interface. The remaining conditions — primarily “includes” filters on subject, sender, or body — are insufficient for safe spam mitigation. Any attempt to delete spam using the current rule set risks deleting legitimate mail, because: All legitimate transactional mail contains “http” All receipts, confirmations, and alerts contain structured HTML Many legitimate first‑contact messages contain links There is no longer a way to exclude legitimate patterns (unsubscribe, structured headers, known senders, etc.) Impact Users cannot safely create rules that distinguish spam from legitimate mail. This leaves them with only two options: Allow spam to reach the inbox Move all messages containing “http” to Junk, which also captures legitimate mail This is a regression in Outlook.com’s functionality and user safety. It also disproportionately affects users who rely on Outlook.com for critical communications. Escalation I have already escalated this issue directly to Microsoft leadership: Satya Nadella (CEO) Brad Smith (President) Rajesh Jha (EVP, Experiences & Devices) Steve Chew (Corporate VP, Outlook & Exchange) Chris Capossela (Chief Customer Officer) I’m posting here to ensure visibility within the Outlook engineering and product teams, and to request confirmation that: This regression is known and being investigated The missing rule conditions will be restored Outlook.com’s spam filtering pipeline is being reviewed for failures in classification or reputation scoring No part of this functionality will be moved behind a paid tier Why This Matters Outlook.com has historically been a reliable consumer‑grade and professional‑grade mail platform. Removing advanced rule conditions without providing alternative filtering controls leaves users unable to protect themselves from high‑volume spam. This is a user safety issue, not a feature request. I’m asking the Outlook team to prioritize this regression and restore the rule capabilities that previously allowed safe and effective spam management. Thank you for your attention.How to block image only spam in outlook?
Keywords aren’t working as any text that appears in the “from” or “subject” field, or message body, is encoded, and/or the body is just an embedded image hosted on a random rotating website. The email domains rotate every single email (they are all just random word + random word @ random word + random word . com) The spam filter is catching them and moving them to junk but I’d like to know if there’s a way to block them or delete them so I don’t even have to see them. I receive so many of these daily from affiliate marketers for the same companies: National Debt Relief, Optima Tax, TruGreen, Amerisave, First American Home Warranty, Thermivest, Keranique, Orangetheory, Miracle Sheets, eHarmony, Empire Today, VSP Vision Plans, Canvas Prints, Jacuzzi Bath Remodel, AARP, Blissy, Healthcare.com, Debt Relief, Life Line Screening, Leaf Filter, JG Wentworth. I never want to see the names of any of these companies in any folder in my email again. Is this possible or am I going to have to go through the hellish process of starting a new email and moving everything over?
