-       Sometimes when attempting to login you will be greeted by a grey screen with a long reference number error on it, this can mean you have bad information cached in your internet browser and it requires being reset.  Below is how to do this in IE, Chrome and Firefox.  
3.    Navigation tips once you’re logged in.
-       The top bar shows the different areas you can explore 
·         The Outlook tab is for your email.
-       Create a new mail by clicking on the New mail button in the top left corner 
-       To respond to an email, highlight the email and choose your reply option in the top right corner 
-       Manage your folders, empty recycle bin from navigation pane on left-hand side of screen.  A great feature of the new OWA is that all items have a right-click context menu available to them.  For example you can right-click on your folders on the left-hand side navigation pane (just like Outlook client) and choose from one of the options 
-       The People menu shows you contacts who you have been in touch with recently but can also be used to send a quick email or Lync IM too by right-clicking and choosing View details. 
-       If you have access to a shared mailbox you can access it by clicking on your picture in the top right corner and choosing Open another mailbox… 
-       Type in the name of the mailbox in the window that pops-up, you can do a search for it by display name if you don’t know the full name.  Once you find it click on the Open button and a new tab will open with the content of the mailbox. 
·         Calendar tab will display a full view of your calendar appointments.
-       You can manage your calendar and any others you have access too from this view.  The right-click context menus are available here as well. 
-       You can view a calendar you have rights to in the top left corner by typing in the name in the Search calendar box in the upper left corner of the window.  From there you will be able to manage the calendar just like you can in Outlook. 
·         The People tab will show you all your personal contacts and contact groups you have created.  You can view all the room, user, distribution lists and contacts directories from this window. 
·         From the Task tab you can view and create new Tasks that will synchronize across all your devices.
Ultimately if you do not like the look and feel of the new OWA you can use the light version of the Outlook Web App, which closely resembles what we used to have with our on-premises system.
-       You can access this from the Outlook tab by clicking on your portrait and choosing Display settings.
-       Click on the Outlook Web App version option then put a check mark in ‘Use the light version of Outlook Web App’ and then click OK at the top.
-       You will need to sign-out of your current internet browsing session and close the program down entirely.  Then once you log back in you will be greeted with the lite version of Outlook Web App.
