Issue noticed : Users complain that outlook is sluggish / status shows disconnected at random intervals
On investigation it was found that the users were part of migration batch and the migration copy process is causing this issue
Users are using outlook in online mode (VDI ) and also users are using cached exchange mode in laptops.
On exchange servers we notice lsass process is using high cpu.
Could you please advise any hotfix which can resolve this issue or is this a known issue.
Then we can schedule migration only during off business hours.
Exchange server OS : Windows 2012 R2
Exchange version : 2013 CU15
Outlook 2010 SP2
