Exchange Webmail Mailbox Hopping
I have setup an Exchange virtual server that hosts webmail for my external users. It uses APM to authenticate and manage the session before passing it off to my internal F5. This all works through a Netscaler just fine and my internal users have no issues. When going through the F5 with APM on it I have this weird issue where a user can hit refresh and all of a sudden they're in someone else's mailbox! Huge issue really. Example: I'm logged in as John Smith. I'm clicking around in my inbox and it gets slow. I hit refresh in my browser and now I'm in Jane Johnson's mailbox and I can read all of her mail.
It's not consistent either. Sometimes it happens and sometimes it doesn't. It's not always the same mailbox I end up in either. Anyone ever seen this before?
