Hello!
We have (5) vm's running Exchange 2013 cu21. Two of them are used for CAS role (One to the production site one to the DR) and the other remaining three are mailbox servers. Two of them are located to PR site and one of them to the DR. What is the problem... OAB stopped working from all Outlook clients (Outlook 2016/2019). The outlook error is Task' mymail@companydomain.com' reported error 0x80072F06: 'Unknown error 0x80072F06'
Could you please let me know what i have to check first?
Thank you
George
