Error: "Sign-in required for … Sign in to the connection again"

The Microsoft sign-in of a connection (MFA) expired or was revoked. Sign in again and run the task again – copied items are skipped.

What it means

Connections that sign in with your Microsoft account (MFA) keep a session, like a browser. The app renews it by itself while it works. This error appears when it can't: the session was revoked, your password changed, a Conditional Access policy asks you to sign in again, or the computer was offline for a long time.

During a running task the app pauses and asks you to sign in again (the Tasks list shows Paused – the sign-in to … expired). If you don't, the task stops with this error.

How to fix it

1. Open Connections, select the connection and click Test. Sign in when the Microsoft window opens.
2. Open Tasks, select the task and click Run again. With Copy if newer (incremental) only what is missing is copied.

If it keeps happening

• Your organization may limit how long a sign-in lasts (Conditional Access sign-in frequency). Ask your administrator, or run long migrations with an App ID connection, which never expires.
• Make sure the account in the sign-in window is the one you expect – a cached account from another tenant is a common cause.
