Hello, I just bought a download product of Office for Mac University 2011 yesterday which includes Word, Excel, Power point and Outlook. All program except outlook are installed perfectly. But when i opened my Outlook, it says that "This identity can not be opened with tho aversion of outlook". I remember that one day before i purchased the office for mac university product from the website, i had download the free trial product for outlook that will last for a month. Does this problem occurred because the free trial product of outlook is still on my macbook? because i already throwed the stuff (outlook free trial) to the trash icon. 

But when i see the product identification number of my outlook, it is the same number with the word,excel and also powerpoint. 

Does anybody know how to solve this? because i can not find the email address for online support for office for Mac. Thank you in advance for your help..

Sincerely,
Agnes
Microsoft Office for Mac 2011 - upgrade and install problems
I downloaded and installed the Microsoft Office for Mac 2011 Trial Version (which worked fine). 
After my trial was up I upgraded to Office for Mac University 2011, while the apps worked fine the main dictionary disappeared from Word Excel etc so spelling errors were not picked up. When I checked the spelling options the "Hide spelling options" checkbox was ticked and greyed out

I followed the instructions in the post "Dictionary/Spell Checker Issue" post, however when I reinstalled Office for Mac University 2011 (without uninstalling office first) I had a number of errors when opening documents. E.g:
- excel: the file could not be accessed 
- outlook: could not change to that identity an unknown error has occurred in outlook

Obviously I should have removed Office for Mac University 2011 before the new install but this was not stated in the article.  Below are some links on removing and reinstalling  office for Mac 2011. Do not do a "complete removal" unless you want to loose all your identity data (eg outlook emails)

I then removed Office for Mac University 2011 per instructions below and reinstalled. After this my Word Excel and Powerpoint worked fine but my Outlook would not open and I got following outlook errors:
- could not change to that identity an unknown error has occurred in outlook
Identity could not open with this version of Outlook for Mac
 After several installs I found a useful site that resolved problem by providing instructions for upgrading  Office 2011 to Service Pack 2 (SP2), I can't recall the site but to do this you simply open Word Excel or another office app that does not have errors, then click "Help" then "Check for Updates". Once the new update SP2 update had been installed my outlook problems disappeared and I had full access to my Outlook identity, archives and emails
