I'm waiting for Veritas to add Exchange 2016 CU 12 to their SCL for Backup Exec. 20.x.
I wonder why there is no urgency on this CU12, cause it is highly critical for security-reasons not covered by normal updates !
My understanding is that support for this CU is being added in the next update (Feature Pack 4) for BE 20.
and when will this be available ? CU12 is high critical
The release is planned for early May - although this may be subject to change.
