Hi,
Since yesterday, all my events in Outlook Calendar have a white stripe under it. Visually, it looks like all my events are terminating 5 or 10 minutes before the next one.
How can I fix it and remove it?
Thanks

    This is all just hearsay. I'm on Version 2608 Build 16.0.20326.20072 and can't reproduce, so I can't test.

    Working (what I think) is the same issue on Reddit.

    Does it looks something like this?

    Hi, Christian de BERAIL

    Since the event times themselves appear correct, the white stripe is likely a calendar-view or rendering problem in Outlook, especially if it appeared suddenly after an update.

    Here are some suggestions you can try:

    Open the calendar in Outlook on the web. If the stripe is not shown there, your events are fine and the issue is limited to the desktop display.

    In classic Outlook, open Calendar, select the View tab, then choose Reset View. This restores the default calendar layout and has resolved similar unexpected calendar appearance changes.

    Close Outlook, press Windows key + R, enter outlook.exe /safe, and press Enter. If the stripe disappears, disable recently added COM add-ins under File > Options > Add-ins. Safe mode temporarily disables add-ins and custom display settings.

    Finally, install the latest Office updates from File > Office Account > Update Options > Update Now, then restart Windows. Recent calendar display problems have previously been corrected through Outlook build updates.

    These steps do not change or delete any calendar events.

    Thank you for your patience in reading, I hope this information has been helpful to you.

    This is usually caused by Outlook’s shorten appointments and meetings setting being turned on, which makes events end early or start late and leaves a visible gap.

    In classic Outlook for Windows, turn it off like this:

    1. Select File > Options > Calendar.
    2. Under Calendar options, find Shorten appointments and meetings.
    3. Clear that checkbox.
    4. Select OK.

    If the setting is enabled and set to End early, meetings can appear to stop 5 or 10 minutes before the next one, which matches the white stripe being seen.

    If using new Outlook instead, go to: Settings > Calendar > Events and invitations Then clear Shorten duration for all events and save.

    This setting is configured per email account, so if multiple accounts are added, check the calendar settings for each relevant account.
