Office 365 Synchronization results in following error:

    Unknown error occured


Due to a large number of objects to be processes during synchronization, the operation takes significant amount of time on the Office 365 Application Endpoint and the initial UI request times out.


  1. Check the current Apache timeout on branding server.

    [root@branding ~] # grep Timeout /etc/httpd/conf/httpd.conf
    Timeout 30
  2. Set a new value. The required value may vary, however it usually takes around 5 minutes to process 1000 objects (users, domains and licenses).

    [root@branding ~] # grep Timeout /etc/httpd/conf/httpd.conf
    Timeout 300
  3. Reload Apache configuration to apply changes.

    [root@branding ~] # service httpd reload
