Why do new calendar events not show up in my calendar?

• Use the Outlook Web version: Try sign-in to Outlook on the web and check if the event appears there. If it does, the issue may be with synchronization between your devices and the server.

The calendar event does not appear on the Outlook Web version. Of course, your concern about synchronization would still apply because I added the event on my desktop app. Should the desktop app not have synchronized with the web, etc, the calendar event would not appear on my apps in other devices or the web. When I forced synchronization for all of my devices, the event still does not appear.

• Update Outlook: Go to Microsoft Store > click your profile icon > App Settings > Click "Get updates" or you can try uninstall and reinstall Outlook.

My app on each of my devices is up-to-date. For example, my work computer is running the latest release: 1.2025.516.400.

• Clear Outlook Cache: save everything you have done and close Outlook. Press Windows + R > press % localappdata% \ Microsoft \ Outlook and press Enter > navigate to the folder RoamCache > select all files, right click and delete them.

When I deleted the cache, no event appeared.

While I appreciate the recommendations, none of the suggestions resolved the issue.

Hi Joe,

Sorry for the late response. We've gathered to examine and investigate together with our engineers about this matter. The root cause comes out to be a possible account mismatch between Outlook and Teams. As required from our experts, we need to ask some questions related to this issue so we can have an appropriate solution for you. We highly appreciate your understanding and cooperation.

• Are you using the same Microsoft 365 account across Teams and Outlook? Is that account work/school or a personal account?
• Do you have multiple accounts or profiles configured in Outlook or Teams?
• Do you know if your Teams calendar linked to your Outlook Calendar via Exchange Online, or are you using a different calendar provider (like Google, iCloud)

Thank you for your patience and cooperation. Hope we can collaborate together to resolve this issue.

Kind regards,

When I add an event in the Teams web app, the event appears on my calendar in Teams. However, it doesn't appear in my Outlook calendar, including my desktop app, my iOS app, and Outlook web app.

I am happy to report that the event created in the Teams web app calendar also appears in the Teams desktop app.

For the sake of trying, I also added an event in my Teams desktop app. Just as with adding an event in the Teams web app, the event did not appear in any of my Outlook calendars, but it did appear in my Teams web app.

While the above is good news, I need my events syncing across all of my desktop and online apps, including Teams and Outlook, in order to maintain my busy schedule. Thank you again for your attention to this matter.
