EoL EWS for O365 (01.10.2026)

Question

Hello Commvault Community,

Is there any information yet on how reconfiguration will be required for EWS running within O365 protection?

Support for EWS for O365 ends on October 1, 2026. There's no information in the Commvault documentation yet – there's still some time left, but we're receiving inquiries from Administrators.
