how to copy outlook.nk2 files into Office 365 for oaming domain profiles

Hi All,

We are currently moving to O365 from Exchange 2007 on-premises and have run into kind of a road block.

Our users have an NK2 file in their roaming profiles and once they move their accounts to O365, when using Outlook 2010, they lose their auto-completed entries.

Is there a way to export/import these contacts so that they can now be used?  With accounts moved to O365, where are the auto complete files now?

Currently the files are being redirected to our profile shares location \\sharename\%username%\appdata\roaming\microsoft\outlook\filename.nk2

your help is appreciated

Regards,

Because you chose not to got the route of hybrid migration, your Outlook clients lose all of their profile customizations--including the nickname (auto-complete) cache, use of the existing OST file, etc.

As a result, you will need to "migrate" (or import) the nickname cache into the new profile.  Use this reference ... https://support.microsoft.com/en-us/kb/980542

The nickname cache cannot, at least not that I know of, be imported into Exchange Online as contacts.

It should do this automatically, at least according to this KB article: https://support.microsoft.com/en-us/kb/2806550

Hi Todd,

Thanks for your response.

When you say 'hybrid configuration' we are currently using a hybrid exchange server.  have we missed a option that would have allowed these settings to be copied across to the users?

When you stated you migrated from Exchange 2007 and also do not have access to the nickname cache, I supposed the mailboxes were migrated as part of a cutover or staged migration or possibly using a third party tool.

And the reason I say that is because with a staged or cutover migration, the Outlook profiles need to be recreated causing the loss of connectivity to the previous auto-complete list, among other things.

If mailboxes were migrated using the hybrid method the continuity of the Outlook profile would not be lost.

Please help me understand if the process I suppose is incorrect.

Eitherway, you should be able to use the reference I provided early to reconnect or import the previous nickname cache.

Additionally, Outlook 2010 and older clients are not supported in hybrid deployments or with Office 365.  They may work but are not supported.
