I bought a new mac book air 13 and installed the new MS office 365 personal. My old Mac book air has office 2011 installed. Tried to migrate the content from office 2011 to the new office 365 personal, but unsuccessful. Nothing was transferred. HELP

What did you do and how did you do it?

There is no content in Office 2011 to migrate. Document files will be somewhere in your Home folder wherever you saved them - usually the Documents folder. Exactly what content did you try to migrate from Office 2011?

I believe those are stored in the Microsoft User Data folder found in your /Home/Documents/ folder which should have migrated with everything in your Home folder if you migrated properly. However, if you already had a /Home/ folder when you did the migration, then your data are all in the other user folder created by the Migration Assistant. If you log out of your current account, then log into the migrated account you should find your data.

This all applies to Office 2011 and all your other migrated data. I don't know a thing about Office 365.

For assistance with Office, you should really ask on the Microsoft Mac forums, as it's their software you're having trouble with and there are MS appointed MVPs there to assist. These forums are for troubleshooting Apple products

There is nothing to migrate from Office 2011 for Mac to Office 2016 for Mac. They are entirely different distributions of Office for Mac, and even install differently. The only content that you should have migrated are the Word, Excel, and Powerpoint documents that you created with Office 2011 for Mac. You will then need to set the preferences in the Office 2016 for Mac (e.g. auto-capitalization) distribution.

Again.. ask on the Microsoft Mac forums.... http://answers.microsoft.com/en-us/mac?auth=1
