not all jewish holidays are showing up

Hi Donald,

Thank you for reaching out and for sharing your concerns.

To ensure that Jewish holidays such as Yom Kippur appear in your calendar, please add the Jewish holiday calendar through Outlook on the web, which will then synchronize with Classic Outlook.

To do this, please follow these steps:

1. Sign in to Outlook on the web with your work account.
2. Go to Calendar.
3. In the left calendar pane, locate the existing Jewish holiday calendar.
4. Right-click the calendar and select Remove.

5. Select Add calendar.

6. Choose Holidays.
7. Search for and select the appropriate Jewish holiday calendar.

8. Return to Classic Outlook and allow some time for the changes to synchronize.

Once synchronization is complete, the holiday calendar should be available in Classic Outlook.

I hope this information is helpful. Please follow the steps above and let me know if it works for you. If not, we can continue working together to resolve the issue.

What are you talking about? There's no calendar to "remove." And to follow your instructions to create a NEW calendar won't work here. All holidays must appear on the main account calendar. And the new calendar you stepped through above has wrong and missing dates.

This is really disrespectful. Either do it right, or remove ALL religious holidays for all faiths.

Hi Donald,

Thank you for your response.

If you’re only seeing “Rosh Hashanah Eve” and nothing after it, please try these steps to subscribe to to an online Jewish holiday calendar:

1. Go to https://www.hebcal.com/ical/, choose Jewish holidays (all holidays), and copy the Subscribe URL.
2. In Outlook on the web, remove the old calendar and add the new one via Add calendar > Subscribe from web.

3. Click Import.

The calendar will appear under Other calendars/My calendars in Outlook and can be viewed alongside your primary calendar.

I hope you found this information useful. Should you have any further questions, please feel free to reach out and let me know. I'll be happy to help.

Thank you for your time and understanding. Wishing you a great day ahead.
