You can use the built-in mail app on your smartphone's OS, or you can use the Outlook app provided by Microsoft.
Please refer to this setup information and try setting it up.

Please select "Exchange" for the setting method.

It is possible to set up forwarding on Webmail (Outlook on the web), but it is not recommended.

Job hunting is an important event for students, but it is also important for the companies that are hiring.

In order not to cause trouble to the companies you desire, be sure to keep the following in mind and make sure to receive important communications reliably.

Please access the password change page and log in with your unified authentication account ID and password.
After logging in, you can check your email address by clicking on the "Office365 information".
After verifying, please log out without changing your password.

The password for your email address is the same as your university-wide unified authentication account.

For reissuing the password of your university-wide unified authentication account, please refer to here.

If you think you haven't received an email, first sign in to Webmail (Outlook on the web) and check again to see if there are no emails.
※If you are setting up forwarding, be sure to check the [Keep a copy of forwarded messages]. If you violate this operation, you may not be able to get relief.

If you cannot find it on Webmail, please check the following items.

• How did you know that you had received an email?
  If you can contact the sender, please ask them if they have received any error messages or Non-Delivery Reports (NDR), and consider obtaining the message text.
• Just in case, please consider whether the sender might have made a mistake in the email address of the recipient.
• If you have any conditions such as who and who doesn't receive emails, or from when they're not received, please contact us in as much detail as possible.
  Or, please let us know the specific email that was not received (Date and time/ Sender (From)/ Recipient (To)/ Subject).
• There is a possibility that it has been determined to be spam.
  Please confirm following this procedure.
  
• Please check the subfolders under the inbox.
  If there is a ∨ mark on the left of the inbox, you can see the list of subfolders by clicking on it.
• Please check if the 'Focused Inbox' setting is enabled.
  cf. Notice 【Office365 Mail】Please be careful with the Focused Inbox setting

Please check the contents of the error email. The following is an example of an error.

• "The message could not be delivered. The Domain Name System (DNS) reported that the recipient's domain does not exist."
  
  First of all, please check to make sure that you have not mistyped the destination address.
  Did you make a spelling mistake, or intend to input in half-width characters but it became full-width characters?
  Please be cautious, especially as it is difficult to distinguish between full-width and half-width hyphens and periods depending on the font being displayed.

Yes, that's correct.

The procedure is shown in the images below.

Please display the settings screen by following the steps below and set it.

1. Our center's homepage and click on "Office365 mail" under "Quick links"
2. Sign in with email address and password
3. Click on the settings (the cogwheel icon at the top right)
4. Click on [Show all Outlook settings]
5. Click on [General]

Please take the time to check your "Spam Email Folder" occasionally.

Especially when there are emails that you think are not necessary, you do not need to do anything.

If necessary emails are incorrectly sorted into the "Spam Folder", they can be moved back to the inbox on the Web Mail by following these steps.
※We anticipate that these steps will improve the accuracy of the spam filter, so we greatly appreciate your cooperation.

It is possible for users to set up a 'spam mail folder' for emails from specific senders (blacklist). However, since attackers often use a large number of email addresses to launch attacks, blacklisting by email address is considered to have limited defensive effect. Overconfidence should be avoided.

Please refer to this article and make settings accordingly in any case.

You can also proceed to the junk mail related settings page from here.

--

Dear recipient, haven't you set up your email forwarding?
