"Some actions taken while the account “AIM” was offline could not be completed online.
Mail has undone actions on some messages so that you can redo the actions while online.
Additional information: Operation could not be completed. (MFMessageErrorDomain error 1028.)"

I had a problem similar to this a while back ago. I tried to repair the disk permissions to no avail, then I posted my problem here and this is what the reply was. The following was the answer I got from David Gimeno Gost
Hi SugaredJuggler.
Problems arising right after installing a system update are usually the result of the problem already being there, or some filesystem corruption that should have been fixed first, or not having installed the update properly (e.g. applications running while installing it), or having ignored Apple’s “Important: Please read before installing” warnings, etc.
Verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
Go to Apple Menu > System Preferences > Network, choose Network Port Configurations from the Show popup menu, and make sure that the configuration used to connect to Internet appears at the top of the list. Leave checked (enabled) only the port configuration needed to connect to Internet and Built-in Ethernet (in that order if not the same), uncheck (disable) the rest of network port configurations, and see whether that helps — if it doesn’t, turn ON again the ones you want enabled.
Try launching Mail under the following conditions (you may need to force quit it first if it’s running) and post back with your observations:
A. Holding the Shift (⇧) key down until the main window appears. This tells Mail to not select any mailboxes or load any messages upon start up.
B. With no Internet connection.
You may also try trashing the Mail cache:
1. (Force) Quit Mail if it’s running.
2. In the Finder, go to ~/Library/Caches/.
3. Locate the Mail cache folder (not to be confused with the ~/Library/Mail folder where all your mail is stored) and move it to the Desktop (to be deleted after opening Mail and checking that all your mail is there, i.e. after making sure that you didn’t remove the ~/Library/Mail folder by mistake).
I then tried opening apple mail with out being connected to the internet and then after it opened I connected to my wireless network and it worked. I hope this helps but without enough information it is a little hard to help you.
