As of now there is no official update by Symantec on support for exhange 2013.
There is no road map which version would start supporting it
Please check this link too
Just to slightly correct the above info as "no roadmap" almost implies we are not even considering supporting it. We are planning to support Exchange 2013 however at this current time we cannot confirm any ETA or whether this will be via updates to existing version(s) of Backup Exec or only against the next complete release.
Some form of public notification will be made once we have specific details.
...ja look, not such a good solution to be honest, especially when you shouldn't HAVE to do that. Symantec was already working on support as the link below states...try hopping onto the Beta...
