Both are context sensitive, changing as the task you're performing changes. I especially like the second level of larger i cons, like the ones for specific e-mail functions. Notes' already noteworthy remote access capabilities are greatly improved in Notes 4. Notes 3's ability to replicate databases to portable PCs and keep these replicas in sync has made it a favorite of road warriors. I discovered that Notes 4 brings even more goodies.
Encryption protects locally stored databases.
This mechanism lets a remote client access its home server by connecting to any Notes 4 server in an organization and passing through it and any other Notes 4 servers on the net work path to its home server. According to Lotus, Notes 3 can handle approximately 200 users per server and Notes 4 supports up to 1,000 users per server. Some of this increased scalability is because of performance improvements, such as field level database replication, while some is attributable to improvements in hardware and operating systems, like Notes 4's ability to run on higher-end computers with multiple processors. Notes 4 has also been optimized for 32-bit operating systems. Notes 4 addresses are stored in X.400 format.
