That usually means the update didn't install properly.
Single server environment? What else is on the server that could have interfered?

Thank you for your response. I have one Exchange 2007 and new Exchange 2013 server.
I was able to solve this issue running following commands (resetting outlook anywhere configuration):
Get-outlookprovider –identity EXPR | remove-outlookprovider
New-OutlookProvider -Name:EXPR
Get-OutlookAnywhere –Server mailservername | Set-OutlookAnywhere -InternalHostname "mail.domain.com" -InternalClientAuthenticationMethod Ntlm -InternalClientsRequireSsl $true -ExternalHostname "mail.domain.com" -ExternalClientAuthenticationMethod Basic -ExternalClientsRequireSsl $true -IISAuthenticationMethods NTLM,Basic -ssloffloading:$false
Get-OutlookAnywhere | ?{ $_.AdminDisplayVersion -notlike "Version 15.*"} | Set-OutlookAnywhere -IISAuthenticationMethods NTLM,Basic
Set-OutlookProvider EXPR -CertPrincipalName msstd:mail.domain.com

Get-outlookprovider –identity EXCH | remove-outlookprovider
New-OutlookProvider -Name:EXCH
Set-OutlookProvider EXCH -CertPrincipalName msstd:mail.domain.com
