We installed Exchange 2016 CU23 and now we our users can no longer access the shared calendars via OWA html links. They get "This calendar isn't available. Please try again."

    Hi Archie Locke,

    According to your description. This problem can occur for one or more of the following reasons:

    • Corrupted items in the user's Calendar
    • Corrupted custom views
    • Corrupted navigation pane settings

    I suggest you can follow the steps below to solve the problem:

    1.Run the Outlook Calendar Check tool (CalCheck). To do so, follow the steps below:

    (1) Download and install the Calendar Check tool for Outlook.

    (2) Open a command prompt window and run the following command at the command prompt:

    calcheck -f -r

    (3) Review the items marked by CalCheck. If you no longer need them, delete them.

    2.Exit Outlook (if it is running) and then do the following.

    (1) Select "Start", type " outlook /resetnavpane " in the search box, and then press Enter.

    (2) Select "Start", type " outlook /cleanviews " in the search box, and then press Enter.

    3.Launch the web version of Outlook and try accessing the calendar again.

    Finally, I would like to ask you if you can access the shared calendar normally through the OWA html link until you update 2016 CU23?
