LastActive attribute gives wrong user status info in Skype for Business Online


In Skype for Business Online, the LastActive attribute occasionally shows outdated information (for example, a user may see a colleague who was online yesterday as "Offline 88 days"). This behavior may occur even when the LastActive attribute is disabled. A user whose LastActive attribute is incorrect can resolve the inaccurate time stamp by signing out and in or by manually changing their presence.


This issue is known to occur in rare scenarios in Skype for Business Online. Due to the highly available architecture of Skype for Business Online, in some rare occasions due to internal failovers that are transparent to users of the service, the LastActive state may not be replicated and some user accounts could end up in this state. This issue impacts a very small percentage of Skype for Business Online users, and typically self-corrects when those users sign-out and sign back into the service.


To resolve inaccurate LastActive data for a given user, have them sign-out and sign back into Skype for Business Online.


You may want to consider removing the LastActive attribute from the aggregation state category in your Skype for Business Online tenant to avoid this issue entirely. See the following article for instructions about how to do that:
