5. Confirm the requested authorization.

When the connection is complete and folders are configured, the profile shows **Connected**.

## Which account to use

Unless impersonation is configured, the e-mail address in the vtenext user profile must match the Microsoft account being connected.

Do not use the same e-mail address for two different vtenext users. This can cause synchronization issues and problems when handling calendar invitations, especially with external users.</div>## Warning when Microsoft access expires

In the new Exchange Connector versions, vtenext checks Microsoft 365 authorization status. If one or more accounts are disconnected or their access has expired, a popup appears in the **vtenext Calendar**.

The warning lists accounts with **Exchange access expired** and provides a **Renew access** action. The user must renew the Microsoft authorization to restore normal synchronization.</div>1. Identify the account shown as **Exchange access expired**.
2. Click **Renew access**.
3. Complete Microsoft sign-in and authorization again.
4. Return to vtenext and verify that the warning disappears.
5. Run a synchronization test if the account remained disconnected for a significant period.

## If Connect or Renew access still fails

Verify that Microsoft sign-in completes all the way back to vtenext, that the vtenext session has not expired and that Office365 configuration is correct. See [User Cannot Connect](https://manual.vtenext.ch/books/exchange-connector-vtenext-Hfx/page/user-cannot-connect).

## When to reconnect

Use **Connect** or **Renew access** when Microsoft authorization expires or is revoked, after an Exchange configuration reset, or when requested by support. If the Proxy/Custom App mode changes, follow [Changing Exchange Type or Connection Method](https://manual.vtenext.ch/books/exchange-connector-vtenext-Hfx/page/changing-exchange-type-or-connection-method).
