Reconfigure the M365 app in inSync using the global administrator’s account.

To reconfigure inSync with Microsoft 365:

On the inSync Management Console menu bar, click the Left_Navigation_Bar_Hamburger_Icon.png icon to access the global navigation panel.

  1. Click SaaS Apps > Microsoft 365

  2. On the Overview page, click Re-Configure.

  3. On the Re-Configure for Backup page,  click Edit_icon.png  > Re-Configure besides the app type that you want to reconfigure. 



Backup will complete successfully after reconfiguration of the M365 app in inSync.
