We generally recommend switching from our [PC connector for Outlook](https://help.staticso2.com/non-visible-articles/pc-connector-for-outlook/non-visible-articles/pc-connector-for-outlook/non-visible-articles/pc-connector-for-outlook/installing-the-pc-connector-for-outlook// "Installing the PC connector for Outlook") to our [direct Office 365 calendar connection](https://help.staticso2.com/options-for-connecting-to-office-365 "Options for Connecting to Office 365"). In all cases, switching is completely safe and all booking data persists.

## Who can switch?

[Section titled “Who can switch?”](#who-can-switch)

Any OnceHub User whose email account is on Office 365. However, the Office 365 Calendar integration does not support [resource calendars](https://help.staticso2.com/user-integrations/exchange-outlook-calendar-connection/connect-oncehub-to-your-exchangeoutlook-calendar "Using Shared Exchange Calendars") and [shared calendars](https://help.staticso2.com/sharing-outlook-calendars "Sharing Outlook Calendars") for OnceHub yet.

If you’re using Exchange, you should connect your calendar using our [Exchange integration](https://help.staticso2.com/introduction-to-exchange-calendar-connection "Introduction to Exchange Calendar connection").

## What happens when I switch?

[Section titled “What happens when I switch?”](#what-happens-when-i-switch)

When you switch, only the connection method is replaced, while the connected calendars remain the same. You are essentially reconnecting via another method to the same email account with the same calendars.

For Users that **only use their default calendar**, busy time will still be retrieved from the same default calendar. All existing bookings will remain in the default calendar, and new bookings will keep being added to the default calendar.

## How do I switch?

[Section titled “How do I switch?”](#how-do-i-switch)
