I do have a user in my organization [SFB on prem] with several FE servers and MBX in a DAG 2016 with an unknown presence status on IM
Troubleshooting done so far
I remote into user’s PC, clear SFB cache client, outlook profile recreated, delete OAB files, reboot computer, no luck
User tried from another computer, same thing.
Fixed the discrepancy with SIP proxy address attribute
Any ideas? What I missed here? Her account was updated yesterday, so OAB replication should not be an issue here.
