We have a Small Business Server box with Exchange Server 2010 SP2
starting about 2 weeks ago we have had trouble getting user emails.
emails to public folders are delivered but user mailbox emails are delayed.
we have rebooted the server and installed updates (not including upgrading to SP3) and sometimes a reboot works and sometimes it doesn't. then all of a sudden users receive emails all at once with the time stamp of the delivery time.
I tried sending myself an email from my gmail account to the exchange account and after half a day received a notice from our exchange server that delivery was delayed..
that raised another concern since now spammers will know when we have an active mailbox. but the plus is that it shows that exchange has the email and is holding it for delivery.
any help to resolve this is greatly appreciated.
