Overlapping emails for active sync

I had this same issue. If you are using the Active Sync iRule provided by F5 (well, it kinda sucks).

They are creating a persistence cookie (sort of) by hashing the IP address of the client. If you have users that are NAT'd to the same IP, they'll end up with crossed streams, and if ghostbusters taught us anything it was to never cross streams.

I'll go dig up what I did to fix this, assuming my assumptions are correct that you are using the stock active sync iRule.

Hi! I believe you are running into ID 479451 which is a known issue.

This is fixed in 11.5.3 HF-2, 11.6.0 HF-4, and 12.0.0 so if you upgrade to any of those releases with the latest hotfix this should resolve your issue.

Thanks Mark and Seth..

As part of my test environment troubleshooting ,following rule making mess. After remove rule..all working as expected.no email overlapping....not sure this rule really require?

Can some one explain about this rule and advantages adding to VIP? iam more concern about if remove on my Prod environment not sure how traffic will behave.

when ACCESS_ACL_ALLOWED { set sessionid [ACCESS::session data get "session.user.sessionid"] HTTP::header insert APM_session $sessionid } when HTTP_RESPONSE { if { [string tolower [HTTP::header values "WWW-Authenticate"]] contains "negotiate"} { ONECONNECT::reuse disable ONECONNECT::detach disable NTLM::disable } if {[HTTP::header exists "Transfer-Encoding"]} { HTTP::payload rechunk } }
