Hi, @Anna Kalinina
Thanks for posting your question in the Microsoft Q&A forum.
According to your description, you encountered a problem about the availability not being displayed in the calendar. The screenshot described in it is not displayed. Can you upload it again? You can try the following steps to check whether settings are correct:
- In Outlook, select File>Account Settings>Account Settings to check whether the Outlook account is an Exchange account.
- Then select the account and click Change to check whether the Exchange cache mode is used.
Just like the following screenshoot:
- Select Other Settings>Advanced to check whether the calendar sharing settings are turned on.
Just like the following screenshoot:
- In addition, you can try to login to Outlook Web App to see if there is the same problem as the client.
