Problem

 

You get this error message when clicking 'update all' in your Xink app for Mac. In this case, your Outlook identity needs to be rebuilt.

 

 

This will also show as missing signatures, where all your signatures are gone.

It is not something we can help further with, so you need to contact your IT administrator or do it yourself.
