Question

I have shared a calendar with my coworkers but one of them can not see it.

Isaiah Nichols 20

I create the schedule at my workplace, and we use Outlook as our calendar. I have never had problems in the past, but recently, I had a coworker tell me that they are unable to see the schedule. This has never happened before, so I deleted her from the schedule and then shared it with her again. This did not work. I have looked online and tried some of the things that I have seen to no avail. Any tips would be appreciated.

I have a shared Outlook Calendar that I use to track Resident appointments. For some reason, resident appointments are disappearing off of the Calendar and other appointments are being added. Only 4 people have editing access and everyone else is only suppose to have view only access. When I go into people who have access, it will not show me everyone. A single pop up page appears and there is no option to scroll down to see everyone. I have the ability to type names in and then that single name will show up but not another page. None of the editors are making these changes so someone else must have that access and they shouldn't. How can I see all of the people that have access on one single page and how can I see who, specifically, is making any changes. Thank you

Hi @Isaiah Nichols,

Good day! Thank you for reaching out to Microsoft Q&A forum.

If your coworker can't see the shared calendar in the New Outlook for Windows, you can try these suggestions you can try:

1. Make sure you're both using the same Outlook platform

You mentioned New Outlook for Windows - if you are using New Outlook and your coworker is on the Classic Outlook, Outlook Web, or mobile app, calendar sharing might behave inconsistently.
Ask them which version of Outlook they are using. Mismatches can cause calendars not to sync or show up correctly.

2. Verify Permissions

Right-click the calendar > Sharing Permissions > Ensure the coworker has at least "Reviewer" access.
You can also check this via Outlook Web to confirm it's not a client-specific issue.

3. Switch back to classic Outlook or Outlook web

Try to switch back to classic Outlook or use Outlook web to see if the issue occurs.

4. Clear Outlook Cache

Navigate to: C:\Users[YourUsername]\AppData\Local\Microsoft\Outlook
Delete cached files, then restart Outlook.

5. Manually add the calendar

Go to Calendar > Add calendar > From directory > choose your account > enter coworker's email > select calendar group > Add.
