Exchange 2010 SP3 rollup 1 causes messages to stick in the Poison queue
June 11, 2013 Leave a comment
It’s always worth monitoring the Exchange Team Blog for each update released for Exchange 2010. Within a couple of weeks you will see from the comments section which problems the update introduces and without fail, each update for the last year or so has fixed problems but introduced different ones.
Exchange 2010 SP3 Rollup 1 was relased a couple of weeks ago and this is no exception. If you use a transport rule to add a disclaimer to messages, then for the moment stay away from Rollup 1 as it causes outgoing messages to stick in the Poison queue. Update 1 does fix a whole bunch of existing bugs which have been around for a while (which is a good thing!) but it is a weight game and depends if the new bugs affect you or not.
You can see many comments about this from the MS blog post about the update release:
