It may be necessary to run the IMailSync application pool with multiple processes should there be a large number of mobile users. System performance will seriously be degraded should a large number of initial synchronizations happen simultaneously. Initial mobile synchronization and complete resynchronization of data tend to have very high cpu usage, depending on the amount of data being synchronized. These estimates are based on moderate mobile synchronization usage. There is no guarantee that the recommendations stated below will exactly match each particular clients needs. These are general guidelines and are an approximation based on in-house performance testing. System Guidelines for Mobile Synchronization Usage Microsoft recommends at least 2 GB RAM for Windows 2008.Heavy use is defined as a mix of IMAP and POP3 users accessing the system with an average mailbox size exceeding 200 MB and more than 40% of users using web and or mobile devices concurrently.Moderate use is defined as a mix of IMAP and POP3 users accessing the system with an average mailbox size less than 200 MB and less than 40% using web and/or mobile devices concurrently.Light use is defined by the system primarily supporting POP3 users with less than 10% of users accessing mailboxes via web mail and/or mobile devices concurrently.Windows Small Business Server 2011 Standard Disk space is dependent on the number of users and usage.TCP/IP enabled network interface card (NIC) with a static IP address.NET Framework 3.5 Service Pack 1Ĭlient Apps (IMail Collaboration and IM Client Installer) Microsoft Data Access Component (MDAC) 2.8 SP1 or later.Microsoft Internet Information Services (IIS) 6.0 and later.For all users still running XP, be sure that all client browsers have been upgraded to IE8 with Compatibility Mode disabled.
