Outlook 2010 is a great improvement over Outlook 2007, but is not perfect. When you open Outlook 2010, it will take some time to load depending on the number of new emails it has detected in your inbox. Once Outlook 2010 is running, it will start sending/receiving information which can sometime take forever if you receive large amount of new emails.
If you started Outlook 2010 to perform a quick task like sending an email, check the schedule on calendar, find contacts, or complete the to-do list, then the fastest route is to run it in Offline Mode.
The first step is to go to Send/Receive tab and hit the Cancel All button. Once it has been cancelled, hit the Work Offline button. Now start using Outlook 2010 for the basic tasks. Another benefit of running Outlook 2010 in offline mode is when the email client hangs up due to large amount of data being send and received.

If you have send an email in offline mode, it won’t be send unless you connect to the server again which can be done from within the same tab. There is no switch at the moment which can allow users to start Outlook 2010 in Offline Mode, but I am looking for a hack.

Great, but after you turn it off, how do you get back online? My Outlook 2010 will not get back online! Any suggestions?
If you have switched to Offline mode, hit the 'Wok Offline' button again to revert back to Online Mode. After this you may also need to hit the 'Connect To Server' button given under the same tab(second button from left), but is not necessary.
If the 'Connect To Server' button is given then you can click it to being downloading messages, otherwise it will automatically connect after 30mins(which is the default time).
Tried this uncountable times with no result. Did a Repair reload of Office, tried the suggestion above and re-hitting the Work Offline button worked fine. Thanks!
Once I turned it Offline, I could not turn it back Online. Clicking it does nothing. There is no “Connect to Server” button anywhere, so I can't do that. There is no way in Outlook 2010 to work online.
Eventually, it did go back Online by itself. Hard to say why. The only reason I turned it Offline in the first place is because I like to download email when I am ready for it and not all the time. This is what I did in 2003. But I had to give up on doing this because in 2010 if you do that then it won't send your Outbox email until the next time you download. What a huge step backward!
Actually when you work offline, it turns of Send/Receive All Folders function. This means you can neither download nor send any email in real-time, but you can send an email and it will be saved in the queue, i.e, it will be send immediately you turn off Offline mode.

I find the longest time waiting on outlook is whilst its loading the program itself. Its frustrating starring at the outlook 2010 splash screen for about 1-2 minutes whilst its even saying “installing outlook” when I bloody installed it weeks ago.

Not so. I an permanently on Offline mode. Ran a repair, tried everything as above, nada. HOWEVER, I can receive emails with impunity. I have had to create a Hotmail account just to send messages out. It is most clunky, shoddy and frustrating.
Finally figured out how to get back to on-line in outlook 2010. Go to send/receive tab and click on the Globe (work offline) This brings it back on-line.
yes, metasense, its the nerdy approach of these wise guys at ms,
i always have been missing:
1. a button to be offline/online
even without using browser or email, i want to be in charge when the system goes online.
2. a button for only sending mail.
it seems to me that the designers at ms miss some fundamental psychological insight.
