Hi guys,
Facing a issue where even newly create mailbox connecting to Outlook Web Apps takes a very long time to login for the first time.
Once the account able to login, the next time the account login to Outlook Web App, there is no this issue.
Internal / External same issue, NLB or no NLB is the same issue as well.
Windows Server 2012 R2 with Exchange 2013 SP1.
32GB RAM with 4 CPU.
Where can I start troubleshoot this problem?
Thanks and Regards,
Low
