    In classic Outlook, calendar colors can be changed in a few different places depending on what changed:

    1. To change the background color of the calendar currently being viewed:
      • Open Calendar.
      • Go to the View tab.
      • Select Color.
      • Choose the color wanted.
    2. To change the default background color for all calendars:
      • Go to File > Options > Calendar.
      • Under Display Options, select Default calendar color.
      • Pick the color wanted.
      • If the same color should apply to all calendars, select Use this color on all calendars.
    3. If the changed colors are category colors on appointments or meetings:
      • Open Calendar.
      • Right-click the appointment, meeting, or event, then select Categorize.
      • Select All Categories to open the Color Categories dialog box.
      • Change the color associated with the category name.
    4. If only one calendar needs a different background color:
      • Open Calendar.
      • Right-click anywhere on that calendar.
      • Point to Color.
      • Pick the background color.

    If the issue is that previously assigned event colors now look different, that usually means the category color changed rather than the calendar background color. In classic Outlook, category colors can be edited from Categorize > All Categories.

    Hi, Homes

    Hi, if the colors changed recently without you changing the settings, first check whether the Office theme changed. In classic Outlook, select File > Office Account, then try White, Colorful, or Use system setting under Office Theme. Dark or high-contrast themes can make the same calendar colors look noticeably different.

    It is also recommended that you update Office. Select File > Office Account > Update Options > Update Now, then restart Outlook. There was a known classic Outlook issue where the Out of Office indicator changed from purple to a lighter color after an Office update. This was corrected in a later build.

    If the issue affects only the calendar layout or shading, try creating a fresh calendar view rather than editing the current one:

    Open Calendar.

    Select View > Change View > Manage Views > New.

    Create a new Day/Week/Month view and apply it.

    A fresh view can help when the saved calendar view has become altered or corrupted.

    Also, please confirm whether all calendar colors changed, or only items marked Out of Office, as that points to different causes.

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