ExchangeBytes

Recently I reposted an article written by a
fellow MCM about BlackBerry and Exchange 2010 Delivery Delays. There has been a
lot of work on this issue and I thought it wise to post an update. Microsoft and
BlackBerry have all but fixed this problem up until last week. Microsoft even
went as far as posting a guidance related to the fix. However, you will not
have much luck in implanting the fix. Microsoft last week pulled Exchange 2010
SP1 RU3 due to a new issue that popped up with BlackBerry Enterprise Server
after installing RU3. The new issue no longer delays messages to BES it
duplicates them. Microsoft is hard at work trying to nail down the problem and
is asking for people to hold off installing RU3. If RU3 is installed and you are
experiencing this issue the update can be removed from the mailbox servers and
functionality should return to normal. For some customers this news is extremely
unfortunate due to the fix in RU3 that enabled UPD notifications for outlook
2003. As information is made available, I will post another update.
