Using Classic Outlook on Windows for personal email, calendar, and contact management
Dear Keith,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
Based on your description I understand you have concern regarding Default calendar (Shared). Please correct me if I am wrong. Thank you.
In order to offer accurate solution, we may need to clarify more details based on the query. Could you please help to provide below information? Thanks so much for your cooperation and time.
Kindly share with us the information below:
- What version of Outlook are you currently using (you can check in Outlook>File> Office Account
- Is it because of the 4th one? Regarding this query do you mean if you remove the 4th calendar you are not encountering the scenario on the latest/3rd shared calendar? You may also a do a test by removing the 3rd shared calendar and add it back to check if you face same scenario.
- Have you tried to restore views
There is an alternative method that can restore the initial views of all folders at once.
1. Close the Microsoft Outlook, and open the Run dialog box with pressing the Win + R keys.
2. Enter the outlook.exe /cleanviewsin the Open: box, and click the OK button.
Then Microsoft Outlook opens with restoring the default views of all folders immediately.
We look forward to your response, Thanks for your cooperation.
Sincerely,
