Hi,
We currently have 2013 installed on a single server with around 40 mailboxes...
We'd like to install CU1 onto this to try and fix some minor issues see if there's any difference.
We've downloaded the update but as it's so large we are cautious about installing this as it appears to be a full install?
If we run this, will this wipe all the current config in terms of mailboxes/transport rules ? Or will it retain all the settings and just install as an update?
thanks in advance.
