Hi all,  I had before a problem with my address book and it was showing mydomain.onmicrosoft.com and most of my users had their autocomplete list in Outlook containing some emails with this domain. 
After the problem was solved and my address book was successfully updated to mydomain.com ,I was able to clear the autocomplete for all my users using Outlook 2010 on Windows. 
But I have 2 users using Outlook 2011 on Mac (which i am not very familiar with) and their autocomplete still show the users with mydomain.onmicrosoft.com and I would like to clear it , how can this be accomplished?

Hello,

I am having a hard time explaining this, but when I am trying to compose a message, I would type the first few letters of a person's name and outlook would autocomplete it. That's not happening anymore and I can't figure out why. 

Any help is appreciated. 

For example, I used to want to send an email to Joe Alstat and in the "To" field I would start typing "Joe" and it would autocomplete for me the rest of the name. 


Thanks for your help.
HI thanks but what i mean is auto complete not auto correct.
this is the feature which gives us option to choose the email address out of the available ones by the same name after entering just first few characters of the person's name or email id  in To, CC or BCC.  any suggestions how i can get this feature to work or reset, it was working fine when i was using outlook on my pervious mac book but after migrating all the data through time capsule to new one with retina, its not working
