I have taken over from a colleague the monitoring of a large inbox hosted on outlook 365. the inbox has accumulated about 100,000 emails. mostly the messages are from two monitoring accounts that report system up / system down sort of activity in an email.
2) I sorted the inbox by the "From" and tried to delete the group of about 50,000 emails. outlook hummed along and reported that it would take about 8 minutes to process. it ran without incident, but at the end none of the emails were actually deleted out of the inbox.
I found out the there is a really good way to do this. Outlook 365 has in the web portal version of office a "sweep" rule that can run periodically through the inbox cleaning up email. The useful option I found was to delete all email older than days from a particular recipient.
Phishing is a popular form of cybercrime because of how effective it is. Cybercriminals have been successful using emails, text messages, and direct messages on social media or in video games, to get people to respond with their personal information. The best defense is awareness and knowing what to look for.
Urgent call to action or threats - Be suspicious of emails and Teams messages that claim you must click, call, or open an attachment immediately. Often, they'll claim you have to act now to claim a reward or avoid a penalty. Creating a false sense of urgency is a common trick of phishing attacks and scams. They do that so that you won't think about it too much or consult with a trusted advisor who may warn you.
First time, infrequent senders, or senders marked [External] - While it's not unusual to receive an email or Teams message from someone for the first time, especially if they are outside your organization, this can be a sign of phishing. Slow down and take extra care at these times. When you get an email or a Teams message from somebody you don't recognize, or that Outlook or Teams identifies as a new sender, take a moment to examine it extra carefully using some of the measures below.
Spelling and bad grammar - Professional companies and organizations usually have an editorial and writing staff to make sure customers get high-quality, professional content. If an email message has obvious spelling or grammatical errors, it might be a scam. These errors are sometimes the result of awkward translation from a foreign language, and sometimes they're deliberate in an attempt to evade filters that try to block these attacks.
Mismatched email domains - If the email claims to be from a reputable company, like Microsoft or your bank, but the email is being sent from another email domain like Gmail.com, or microsoftsupport.ru it's probably a scam. Also be watchful for very subtle misspellings of the legitimate domain name. Like micros0ft.com where the second "o" has been replaced by a 0, or rnicrosoft.com, where the "m" has been replaced by an "r" and a "n". These are common tricks of scammers.
Never click any links or attachments in suspicious emails or Teams messages. If you receive a suspicious message from an organization and worry the message could be legitimate, go to your web browser and open a new tab. Then go to the organization's website from your own saved favorite, or via a web search. Talk to them using official numbers or emails from their site. Call the organization using a phone number listed on the back of a membership card, printed on a bill or statement, or that you find on the organization's official website.
Microsoft 365 Outlook - With the suspicious message selected, choose Report message from the ribbon, and then select Phishing. This is the fastest way to report it and remove the message from your Inbox, and it will help us improve our filters so that you see fewer of these messages in the future. For more information see Use the Report Message add-in.
Choose OK to save your new signature and return to your message. Outlook doesn't add your new signature to the message you opened in Step 1, even if you chose to apply the signature to all new messages. You'll have to add the signature manually to this one message. All future messages will have the signature added automatically. To add the signature manually, select Signature from the Message menu and then pick the signature you just created.
Admins can configure how long messages are kept in quarantine before they're permanently deleted in anti-spam policies. Messages that have expired from quarantine are unrecoverable. For more information, see Configure anti-spam policies in EOP.
A quarantine policy can allow you to release a message or request the release of a message, but both options aren't available for the same message. A quarantine policy can also prevent you from releasing or requesting the release of quarantined messages.
The organization can still receive mail from the blocked sender. Messages from the sender are delivered to user Junk Email folders or to quarantine. To delete messages from the sender upon arrival, an admin can use mail flow rules (also known as transport rules) to Block the message.
NDU highly recommends that you DO NOT modify your MS Outlook settings to encrypt contents and attachments for ALL outgoing messages, as this may prevent many of your email recipients from opening your email. Encryption works best when the sender and receiver have previously communicated with each other via digitally signed emails, and when both choose and agree to exchange unclassified information that requires encryption.
Upon retirement from UofL, depending on your status or eligibility, your email account will either remain open or you are able to set up an email forwarding option to keep receiving new emails sent to your UofL address. Please be informed on your choices as it is best to set up your option prior to your last day at UofL. If the account is retained and a retiree does not access their email within the first six (6) months, the account will be closed due to lack of use.
Access your email and calendar online from anywhere in the world on any internet-enabled device by logging into Outlook Office 365. Just enter your KU email address and you will be taken to the standard KU log in page where you will enter your KU Online ID and password.
We strongly recommend that you do not auto-forward your KU email to an external personal email account. By doing so, you may miss important emails, and unintentionally compromise the security of both your personal device and confidential KU information or data. Read more about email forwarding.
Advanced Threat Protection (ATP) not only helps protects you from malicious emails, it also helps reduce annoying spam. It can prevent unwanted or harmful emails from ever reaching your inbox. In addition, ATP protects in other ways:
Encryption is a way to send an encoded message that can only be decoded by someone with the proper key. A digital signature is a mathematical algorithm that helps validate that a message is from the stated sender, and that the content of the message has not changed since it was sent.
Departmental email accounts are available to departments and campus organizations, and are associated with a task or function. Examples of departmental accounts include purch...@ku.edu, musi...@ku.edu and des...@ku.edu. A departmental email account allows multiple people in the department or organization to check and respond to emails to the account.
Starting May 10, 2023, every email communication to BYU students from a BYU entity must be sent to the student's BYU-provided email. This change is to help BYU align with security best practices and federal regulations (FERPA).

Let's face it, the world is dependent on email for communication. William & Mary is no exception. We have relied on Microsoft as a email service since 2010. In 2017, we transitioned our onsite Exchange servers to Microsoft Office 365, which is a Cloud service. In 2022, we transitioned all students from Gmail to Outlook. Here's what you need to get started with Microsoft Office 365 Email.

In an effort to protect the William & Mary community from email borne viruses, Information Technology is removing self-executing attachments from emails sent to or from William & Mary email addresses. Attachments created in Microsoft Office will not be affected by these new restrictions.
If you need to send a file of a prohibited file type as an attachment, we suggest you use Box (box.wm.edu) instead. If you have any questions or need help with sending an attachment, please contact the Technology Support Center at 757-221-4357 (HELP) or [[support]].
