After you migrate, here is the big "to-do" list
Do you want to change your primary address to email@example.com?
you CAN use your old WiscMail Plus address (e.g., firstname.lastname@example.org) as primary
you still log in with NetID & password
changes you need to make (e.g., directory, chat client, WiscLists, Box.com, clients to send as alternate, UW Digital Certificate, etc.)
Setting your vacation message (aka, "Automatic replies")
Log into OWA, click on the gear icon and select "Automatic replies"
Make the appropriate selections, choose your dates, & type in your automatic replies
NOTE: make sure to scroll down since there are TWO parts of the automatic reply, an inside organization message and an outside organization message
Select the appropriate settings and put a message in both boxes
NOTE: often you will need to repeatedly save the messages before they "stick"
sometimes adding a hard return below your messages and saving them again will make it 'stick'
Changing your account profile information
This is now (as of September 2015) is done in the Personal Information app/section of my.wisc.edu.
Go to https://my.wisc.edu/ and log in with your NeID and password.
Search for "Personal Information" and change your Preferred Name to what you would like displayed.
Calendars in OWA
to open a new calendar
right click on "Other calendars" and select "Open calendar"
search for desired calendar in "From directory" box
you can search for people (full names) or rooms (usu. building)
to share your own calendar
follow these directions
Other known quirks
Forwards and forwarding
Whereas UW's Office 365 team initially said forwarding can't be trusted completely within Office 365, since then it appears that forwarding (even to non-wisc.edu addresses) is functioning consistently and well.
OWA may get "stuck" on the Calendar view
to get off it, click on People or Apps > Contacts
when writing new messages in a pop-out window
sometimes OWA does not supply a place to type your message
Resize the new email window and it should open to normal size
signatures and automatic replies
often signatures and automatic reply messages do not save when you try to add them
double-check after saving and make sure your signature or replies save
Quirk Alert: repeatedly saving the signature or replies and/or adding a return below them and saving will usually resolve the issue
If you have another Office 365 account with another institution (e.g., UW-Milwaukee, UW-Eau Claire, etc.), be aware that after typing your NetID and password at https://wiscmail.wisc.edu and clicking on your NetID password (sometimes even a Service Account!) you will sometimes be logged into your O365 email account at the other institution. This behavior is likely related to cookies in your browser.
logging into a browser in incognito or private browsing mode will usually resolve the redirect issue
Mail app on Macs (esp. OS X 10.10)
after setting up your new Office 365 Wiscmail account, there is a long delay in mail showing up
to resolve, open the Mail app and go to Mail > Preferences > General, and change the "Check for new messages:" option to "Every minute" or (if your account is larger than 5 GB) "Every 5 minutes"
the "Automatically" setting doesn't always check regularly and some people have seen delays up to two hours
