Exchange CU Installation
Do we need to run /Preparealldomains if we have Exchange server and mail-enaled objects present in all of the domains. what if we are responsible only for few domains ( out of all ) and need to run /Preparedomain only on those domains, can we still install Exchange CU in the Exchange servers in the domain for which we ran /preparedomain.
And after running /PrepAD and /Preparedomain, and installing CU on just one of the server, can we delegate the installation to another team which do not have Org management role ?
- Not all CU update require AD prep or schema updates. If this is required, then you can have your schema admin do the prep and your domain admin do your AD prep, then hand off the CU installation to the Exchange admin. Details of AD prep for forests are outlined in the below link, including how to prepare only specific domains in the forest
