O365 Clearing AutoComplete and other Recipient Caches

[edie209]

I am looking to do this for all users I can find plenty of info to do it for one user but nothing for multiple users or the entire site.

 

The reason we need to do this is because we have changed our email addresses last summer to tie in with usernames but some staff are struggling with the idea due to old addresses being still n cache

Looking same here with old email addresses and distribution group names. - would be very handy if anyone knows.

Is this Outlook for OWA? If its Outlook you need to delete the NK2 file but aware some people rely on this for their address book and never save any addresses into the address book.
