I just thought I'd share this in case there were others that were not aware. I have been unable to sync my corporate calendar with my Droid due to lack of a security policy from my employer. Recently I've just tried to add most things to my Google calendar manually.
Yesterday I came across something on accident. I had a off-site meeting and wanted to forward the address to my phone. I simply forwarded the actual meeting invite to my gmail account so I would have the address handy if needed. I actually didn't need to reference the email and made it to my meeting without any help. After sitting thru the meeting I noticed I had a calendar alert on my Droid. I was confused as I hadn't added this meeting to my Google calendar or my phone and I didn't have anything else scheduled for that time. When I looked at the actual alert it was for the meeting I was in.
Well it appears all you have to do is forward an Outlook meeting invite to your gmail account and the Google calendar updates automatically, without any input from the user. I thought this is pretty cool/easy way to keep your google calendar in sync with your corp account.
Sorry for the long post, I just wanted to share in case anyone else had a employer that wasn't able to sync to their Droid.
