We have around 200 Mac Office users where the nickname / autocomplete is not working correctly. We have tried the usual steps of rebuilding the identity and the index on a percentage of these to no avail.

The inclusion of the names into the nickname / autocorrect is sporadic. Some do show and others do not without any pattern being detected. We are on 14.5.1 with Yosemite.

Webmail and Outlook 2013 work as expected. Its becoming increasingly frustrating for our users and I know from our own research it is still an issue for many.

Thanks.
