We are in the prosess of implementing Lync to all our employees. We have a problem for some of our users. The error message on the client is.
"Cannot sign in to Lync: Please sign out at another location and try again. You have reached the maximum number of computers or devices allowed"
We have verified that they only are singed in to one device. The ten users with the problem all have first name starting with the letter "A". I don't now if this is a coincidence.
They can log in but get loged out whe the error appears. If they try to log in again it works after trying some time. The users get the error several times each day.
