how do I stop multiple calendars in outlook from merging under the same email

To prevent multiple calendars from merging in Outlook, you may need to ensure that you are not adding events to a shared calendar or a calendar that is set to display all events together. Here are some steps you can take:

1. Check Calendar Settings: Make sure you are selecting the correct calendar when adding events. You can do this by clicking on the calendar dropdown in the event creation window and selecting the specific calendar you want to use.
2. Separate Profiles: If you have multiple calendars that you want to keep completely separate, consider using different Outlook profiles for each calendar. This way, each profile will manage its own set of calendars without merging.
3. Delegate Access: If you are a delegate for someone else's calendar, ensure that you are not inadvertently adding events to their calendar instead of your own.
4. Manage Shared Calendars: If you have shared calendars, check the permissions and settings to ensure that events are not being automatically added to your personal calendar from shared calendars.

If these steps do not resolve the issue, you may want to consult the Outlook support documentation or your IT department for further assistance.

Hi @Mattix, Marie,  

Welcome to the Microsoft Q&A forum.   

Thank you very much for reaching out regarding the issue with multiple calendars merging in Outlook. I really appreciate you taking the time to describe what you're experiencing. 

From what you described, it sounds like events created in one calendar are also appearing in your other calendars under the same email address. I understand how confusing this can be, especially when you're trying to keep your calendars separate. 

Outlook Web supports multiple calendars under one account but still relies on a single default calendar, so when you create a new event it automatically uses either the default or last‑used calendar meaning the event may be saved to the wrong one if the correct calendar isn’t selected, and the overlay view can make separate calendars appear merged even though they remain distinct. 

Here are my recommendations, which I hope will be helpful to you:  

1/ To ensure events go to the correct calendar: 

When creating a new event: 

1. The calendar selector appears directly under the Save button at the top of the event window. 
2. Click that selector to choose the correct calendar before saving. 
3. 

Note: If you don’t see the calendar selector, please make sure more than one calendar is enabled in the left panel. The option only appears when Outlook Web detects multiple active calendars. 

Optional - to avoid the calendars appearing merged: 

In Calendar view, open the left sidebar and uncheck the calendars you don’t want to display. 
Outlook Web will only show the selected calendars, preventing them from appearing combined. 

For additional details, you can refer to this Microsoft's article: Working with multiple calendars in Outlook on the web - Microsoft Support.
