Exchange 2013 CU8

Exchange 2013 CU8 (Cumulative Update 8) was released on 3-17-2015.  Note: CU8 has recently been replaced, click here for CU9.
Some of the CU8 features we’ve have heard about so far:
  • CU8 contains the new signout.aspx page, but the code will by default continue to send users logging off to logon.aspx.  The new code can be manually enabled if one chooses.  Once CU9 comes out the new code will be enabled by default.
  • Improved Public Folder migration experience.  Improved throughput of Public Folder Batch Migration to Exchange 2013
  • The maximum number of Public Folders has increased once again for on-premises deployments (Office 365 PF limits remain the same)
  • Smoother migration for EAS clients to Office 365 with automatic profile redirect upon successful Hybrid migration to O365 (EAS client must support HTTP 451 redirect)
  • “Contact and Calendar Modern Public Folder favorites added in Outlook are now accessible in OWA.”  UPDATE: The statement about this new OWA fix/feature found in some MS CU8 materials may be inaccurate.  Reports are coming in that Contact/Calendar Public folders are not made accessible after installing CU8.

New issues introduced in CU8:

  • Some Android devices may not be able to create a new mail account due to the new MobileSyncRedirectBypass in AutoDiscover https://support.microsoft.com/en-us/kb/3035227

I’ll keep this post updated as I find out more about the fixes contained in CU8.

    I just updated to CU8 on an on-premise single exchange server environment, spent 4 hours with Tier 2 Tech support at Microsoft, the tech spent the weekend recreating my environment and was unsuccessful in configuring the public calendars and public rolodex’s we have in our public folders. It was determined as of yesterday when I heard the news from Microsoft Support, that the info above is not accurate. Here is the website which lists the actual updates included in CU8:

    https://support.microsoft.com/en-us/kb/3030080

    No where in the list does it state that mail enabled public calendars and public contacts are assessable over OWA.

    Microsoft Support then refunded my the $530 for support and apologized for the false info Microsoft Released regarding the FAQ’s of CU8. They are escalating their findings to the Exchange developers to follow up on why these were not included as announced and published prior to CU8’s release.
