6. What do you mean by ‘too many connections’?

This problem is not limited to Outlook and IMAP clients can have similar issues. Multiple machines/devices connecting to the same mailbox(es) can cause or exacerbate performance problems. Whilst some session limits are per IP address, many are per authenticated session so if (for example) your mailbox contains 251 folders and works quite happily on one machine, and if you leave Outlook running at home, and possibly also on your terminal server, and possibly also on your mobile device you may easily exceed your available system resources and you will see problems.
