 NOTE: After upgrading the Plug‑in for Microsoft 365 from version 13.4.1 to 14.0, the next execution of existing CDP and non-CDP incremental jobs will be treated as a full backup. 
NOTE: When upgrading the Plug‑in for Microsoft 365 to version 14.0, ensure to maintain at least one client with the 13.x plug-in to restore backups of the 13.x plug-in. It is mandatory to install the version 14.0 plug-in on a new client if there is only one proxy plug-in. It is recommended to maintain the machine’s availability until the backup using the 13.x plug-in has expired.  |
