Administrators of Exchange 2010 who have more than 50 databases can now be happy.
Exchange 2013 enterprise has limit of 50 databases per server, but not with CU2 !!!!
Exchange Team has released that many of us have Exchange 2010 environments with more than 50 databases. And during migration to Exchange 2013 enterprise it could be a problem to decrease number of mailbox databases to 50 per server.
So when you install CU2 for Microsoft Exchange 2013, mailbox databases limit for enterprise version will be increased to 100.
CU2 is expected later this summer.
CU2 won’t change number of databases pers server for standard edition, and it will be 5 per server.
