Office 365

Olin College has migrated email and calendar services to the Microsoft Office 365 cloud environment. As of September 2018, all Olin College electronic mailboxes are located in Office 365.

Online Training Resources

UPN - UserPrincipalName

The User Principal Name, or UPN, is used to login to Office 365 sites and services and is in this format: “” (e.g. Joseph Student = It will be added to your mailbox as an additional email address and eventually become your primary email address. This is necessary since Microsoft's O365 sites and services prompt users to login with their email address and therefore will be easier to remember. When an O365 site prompts you to login with your email address, it's expecting your UPN.

Migration to the O365 Exchange Environment

Once your email is migrated you should see a new window stating that you are required to close and restart your email client. Make sure your username is in the UPN format(e.g. Joseph Student = not listed as domain\username (e.g. Joseph Student =\jstudent). You will have to do this on all your email clients. If you have additional mailboxes configured in Outlook that haven’t been migrated, you will likely be prompted to login again via a popup window. This is because you need to authenticate to the two different mail locations, our systems on campus and the cloud.

O365 Device Setup

Mobile device and other clients will need their configurations updated to point to Exchange online. The following guides may be followed noting two exceptions:

  • Office 365 Mail Server:
  • Username must be in UPN format (noted above):

Items of Note

  • Web access to your migrated mailbox will now be through O365: to Login, sign in with your UPN or new email address: and existing password
  • If you have registered for Microsoft services using your current Olin email address (, those services will remain separate from any new O365 services associated with Olin.
  • Email Forwarding can also be set up through this O365 Portal. Once logged in as directed above, select the Outlook icon and then choose the settings gear icon in the upper right corner. From the settings pane, select the mail option at the bottom under Your App Settings. The mail options pane will now open on the leftt hand side. Go to Accounts and then choose forwarding. Select the option to forward mail and enter a forwarding mail address.

Known issues and Resolutions

Public Calendars

You will not be able to access calendars that live in the Public folders from within the O365 web portal. Access will be limited to your locally installed client.

If you experience an issue accessing the public calendars from your installed Outlook application with any of the following error messages, please contact the helpdesk as we can resolve the errors by rebuilding your Outlook profile.

When opening public folder calendar in Outlook from calendar view receive error: “Microsoft Exchange is currently busy. If this message is still displayed in 30 minutes, contact your Exchange administrator”

If Favorites shows a number of items populated on calendar, however it errors stating that it cannot open the folder.

Or if All Public Folders > Calendars shows similar error that it cannot open folder.

Rules: Export and Import

If your existing Outlook rules do not work after migration, you can try exporting and re- importing them. Some rules may need to be edited manually to get them to work again. When you export rules, they will be saved in a file with an .rwz extension. This file type can only be opened and used within Outlook.

  • Click the File tab then select Manage Rules & Alerts.
  • Click the Options tab then select the Export rules button. Change the name and take note of the save location (or save it to your desktop temporarily) Click Save.
  • to import your rules:
  • Click the Options tab then select the Import rules button. In the “import rules from” window go to the save location you chose and then click Open. In the Options windows click the “OK” button and then the “Apply” button in the rules and alerts window.

Post Migration

It may take a few minutes for your local client ( Outlook, Apple Mail) to fully sync and that may make initial usage appear slow. This clears up quickly.

Receiving messages may be microscopically slower as the mail server is now in the cloud and not on the Olin network.

A small number of test subjects found it necessary to remove and re-add account credentials on mobile devices.
