Shared Calendars No Longer Visible
For years, I've shared Outlook calendars between my Outlook accounts and with my husband's, without any issues. However, since mid-June the shared calendars have disappeared for no apparent reason. The sharing permissions are still in place, but the calendars are no longer visible or available to add on Android, in the Outlook desktop app, or on Outlook on the web. I've spent hours Googling and tried all the usual troubleshooting steps, but nothing has worked! As a workaround, I now have to invite all @outlook.com accounts to calendar events just so everyone can see them and avoid double bookings. Has anyone come across this before and found a fix that isn't one of the standard "how-to" suggestions? Note: these are personal paid Microsoft accounts.15 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.

[Bug] ExchangeOnlineManagement uses incorrect TenantId in requests
An interaction between the ExchangeOnlineManagement powershell module and Microsoft.Identity.Client 4.83.0+ results in the REST API requests sent by the ExchangeOnlineManagement powershell module using realm.onmicrosoft.com in place of the expected Guid TenantId. This results in the dreaded Expired or Invalid pagination request after fetching one page. As discussed in https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/issues/6093, Microsoft.Identity.Client.AuthenticationResult.TenantId can no longer be trusted to contain either null or the expected Guid TenantId, but instead will generally contain the realm.onmicrosoft.com realm name as of Microsoft.Identity.Client 4.83.0 As version 3.10.0 of the ExchangeOnlineManagement powershell module now depends on Microsoft.Identity.Client 4.83.1, this version of the powershell module can no longer retrieve groups with more than 1000 members or enumerate the groups, contacts, recipients, etc. in a domain that has more than 1000 of each without running into the dreaded Expired or Invalid pagination request. In theory the following Lib.Harmony patch encodes a potential fix for this issue (tested locally using ExchangeOnlineFetch 3.10.0 in a dotnet 10 program): using System.Reflection.Emit; using HarmonyLib; [HarmonyPatch("Microsoft.Exchange.Management.AdminApiProvider.Authentication.TokenProviderUtils", "GetTokenInformation")] static class Patch_TokenProviderUtils_GetTokenInformation { private static Harmony? _harmony = null; public static void PatchOnce() { var asms = AppDomain.CurrentDomain.GetAssemblies(); if (_harmony is null && asms.FirstOrDefault(e => e.GetName().Name == "Microsoft.Exchange.Management.AdminApiProvider") is { } asm && asm.GetType("Microsoft.Exchange.Management.AdminApiProvider.Authentication.TokenProviderUtils") is { } type && type.GetMethod("GetTokenInformation") is { } method) { var harmony = new Harmony("com.github.klightspeed.exchangeonlinemanagement.tenantidfix"); harmony.Patch( method, transpiler: new HarmonyMethod(typeof(Patch_TokenProviderUtils_GetTokenInformation), nameof(Transpiler)) ); _harmony = harmony; } } static IEnumerable<CodeInstruction> Transpiler(IEnumerable<CodeInstruction> instructions) { var matcher = new CodeMatcher(instructions); var get_TenantId = AccessTools.PropertyGetter("Microsoft.Identity.Client.AuthenticationResult:TenantId"); var get_Organization = AccessTools.PropertyGetter("Microsoft.Exchange.Management.AdminApiProvider.Authentication.TokenProviderContext:Organization"); // patch the following code snippet: // // if (IsCertificateBasedConnection(context)) // { // var upn = GetUPNForAppOnlyBasedConnection(context); // var tenantId = JwtSecurityTokenUtils.GetTenantId(tokenAcquisitionResult.AccessToken); // return TokenInformation.Create( // upn, // authorizationHeader, // tokenAcquisitionResult.TenantId ?? tenantId ?? context.Organization, // tokenAcquisitionResult.ExpiresOn // ); // } // // to // // if (IsCertificateBasedConnection(context)) // { // var upn = GetUPNForAppOnlyBasedConnection(context); // var tenantId = JwtSecurityTokenUtils.GetTenantId(tokenAcquisitionResult.AccessToken); // return TokenInformation.Create( // upn, // authorizationHeader, // PatchedTenantId(tokenAcquisitionResult.TenantId, context) ?? tenantId ?? context.Organization, // tokenAcquisitionResult.ExpiresOn // ); // } matcher.MatchStartForward( new CodeMatch(CodeInstruction.LoadArgument(0)), CodeMatch.Calls(get_TenantId), new CodeMatch(OpCodes.Dup), new CodeMatch(OpCodes.Brtrue_S), new CodeMatch(OpCodes.Pop) ); if (matcher.IsValid) { matcher.Advance(2); matcher.Insert( CodeInstruction.LoadArgument(1), new CodeInstruction(OpCodes.Call, get_Organization), CodeInstruction.Call(() => PatchedTenantId(default, default!)) ); } return matcher.InstructionEnumeration(); } static string? PatchedTenantId(string? tenantId, string? organization) => tenantId == organization ? null : tenantId; }

Teams Meeting Add-in Not Appearing in Outlook
The computer was rebuilt from scratch and reinstalled with a clean operating system. After the installation, all required Microsoft applications (Outlook, Teams, etc.) were installed and the user successfully signed in. However, the Teams Meeting add-in is not appearing in Outlook as expected. Within the Outlook Calendar/Appointment window, only the Skype Meeting option is visible, while the Teams Meeting option is completely missing. Checks Performed: New Microsoft Teams is installed and functioning properly. Outlook and Teams are both signed in with the user account. Outlook COM Add-ins have been checked. Disabled Items have been checked. Teams Meeting Add-in for Microsoft Office has been verified. Outlook updates have been checked. Microsoft Teams has been reinstalled. Outlook profile has been verified. Exchange mailbox is active and functioning correctly. Despite all the above checks, the Teams Meeting option is still not displayed in the Outlook Calendar/Appointment window, and only the Skype Meeting integration is available.

Request: Please why the Teams Meeting Add-in is not being loaded into Outlook and provide assistance in restoring the Teams Meeting functionality within the Outlook Calendar/Appointment interface. Attachments: Screenshot showing the current issue (Teams Meeting button missing) Screenshot showing the expected behavior (Teams Meeting button visible)
Shared Outlook Calendar disappeared
An Outlook Calendar that my wife and I share has suddenly disappeared from my Outlook Calendar. It still shows on my wife's computer. We set this up a number of years ago, so I have no idea where or how to troubleshoot this. I do recall that we had to each create outlook.com email addresses so that we could access Microsoft Exchange. We are using the Classic version of Outlook. In case it's useful, here's the exact information from the Outlook About page: "Microsoft® Outlook® for Microsoft 365 MSO (Version 2605 Build 16.0.20026.20168) 64-bit." Thanks to anyone who can help me solve this problem.
Techcommunity Follow email notification no longer working
Hello, Not sure if this is the right place to post this issue but I could not find another method to report this issue.. As an Exchange Admin in our invironment it's very usefull to stay up to date on the latest new posted in a variety of blogs on this website (Exchange Blog, M365 Blog, ...) This all went well until a few months ago where I started noticing I didn't receive any weekly updates anymore regarding new blogposts & tried to manually go check periodically, thinking it would be a temporary system. After investigation i've noticed that i'm not the only admin in our company that no longer receives these emails from mailto:email address removed for privacy reasons So I wonder if something bigger is up or if it's only my company being affected, not receiving these follow notifications anymore? Is there any other way that I should report this issue, to those managing this website so it can be investigated in detail if it's only us? Already tried to unfollow/delete follows in my profile - save - follow again, same on the respective blog pages, but this does not seem to change anything.My Outlook for Mac HTML email reply quoted body blank, only headers show
I've been using Legacy Outlook for Mac for years without issues, but since Wednesday afternoon (June 17, CET) something broke after the latest update rolled out. When I reply to any HTML email, the quoted original message is completely blank. Only the From, Date, To and Subject headers show up — the actual email body is gone. It makes it impossible to have a proper email thread because the recipient can't see the conversation history. This started right after Version 16.110 (Build 26061317) was released on June 16, 2026. The release notes only mention "Quality and performance improvements" for Outlook, so whatever changed in this build seems to have broken HTML reply quoting as an unintended side effect. My setup: MacBook Air M5, macOS (Legacy Outlook for Mac Exchange on-premises account (EWS), domain login What I'm experiencing: Replying in HTML mode → quoted body is completely blank, only headers show Switching to plain text → body comes back but with massive blank line gaps throughout (not professional to send) Outlook Web (OWA) → works perfectly fine What I've already tried: Cleared app data (Document Cache + Experimental Features) — no fix Cleared Outlook cache manually — no fix Toggled composing settings — no fix Checked settings in Preferences → Email → Composing — everything looks correct I've also tested Apple Mail as an alternative but it breaks embedded signature images (CID images show as placeholders), and it doesn't support Teams meeting integration — so going back to Legacy Outlook is really the only option for my daily work. Outlook Web App OWA is my current workaround but it's not sustainable long term. I really hope this can be looked at as a regression fix in the next update. Has anyone else experienced this since the June 16 build? Does anyone has this issue as well?Decommission from one tenant to become separate tenant
