Using Classic Outlook on Windows for personal email, calendar, and contact management
Dear Fnurk,
Good day!
Thank you for posting to Microsoft Community. We are happy to support you.
Based on your description, I understand that you have a query " Outlook asks to save when closing appointments without any change ",After thorough research and test, I would like to provide you with the following information:
1.May I know if both client and web versions of Outlook have the same issue? Please log in to the Outlook Web App https://outlook.office.com/ and test here to see if there is the same situation.
If it could work normally on your web mail, the issue may be related to your client itself. Based on my research, any add-ins may cause it, it's recommended to restart your outlook in safe mode to check if the issue has any differences(Windows + R >type "Outlook.exe /safe">enter).
If you could work normally in safe mode, it's recommended to disable your add-ins gradually to check which one causes the issue(File>Options >Add-ins>COM add-ins, Go>uncheck the add-in to disable it).
If the issue still exists, considering corrupted outlook data file or profile may also cause it, it's recommended to create a new Outlook profile for testing(Control Panel>Mail>Show profiles>Add>readd your account) Do not delete the old profile, if this method does not work, switch back to the original, please refer to: Create an Outlook profile - Microsoft Support
2.
If you are using multiple monitors, check to see if the display scale of each is the same.
If they are not, set them both to the same display scale.
(Right click on the desktop, "Display settings", "Size of text, apps, and items on this display")
For example, if you have two monitors with different display scales and the appointment window is opened on a monitor other than the one where the main Outlook window was first opened, you will be prompted to save the appointment even though you are not editing it. If you have multiple screens, please set display scale = 100%3.When you click on a link (e.g. to open a Zoom or Webex link) you have clicked into the body of the meeting causing the application goes into Edit mode. Once it's been in edit mode, it cannot be closed until you save or discard changes.
4.Go to File -> Options -> Calendar and unchecking Show weather on Calendar. If the weather changes while the appt is open, it prompts to save changes before you can close it. Hope this information is useful to you. If there is any progress on the issue, please update it with this post and we will do our best to help you. Thank you for your patience and cooperation, I wish you all the best!
