Microsoft is to formally unveil the latest version of its Exchange messaging product at Comdex on Sunday.
The product will be available from UK distributors in the first week of December, said Phil Cross, group marketing manager for Microsoft UK.
Exchange 5.5 will include key products from the software giant's acquisition of Linkage Software in June. These include connectivity with Lotus Notes servers, IBM Office Vision and Profs, plus SNAD-compliant messaging systems.
Microsoft has also worked on its often criticised scalability limitations. Each server will support a maximum of 50,000 POP3 users from 15,000 in version 5.0, and 8,000 MAPI users from 2,000. The latest release also includes support for Internet standards such as IMAP4, LDAP, and Mime. Exchange 5.5 will be able to support up to 15,000 IMAP4 clients.
Backup and restore times have also been boosted - by up to four and three times faster, respectively. Microsoft also claims 5.5 will have an ?unlimited? data store facility of 16Tbytes, backing up at 25Gbytes an hour.
The product will be available as a standard and enterprise edition with the latter supporting clustered NT servers. Exchange 5.5 will be available as a server but not client upgrade to existing users.
