What file types are blocked and cannot be uploaded or sent as attachments?

September 14, 2017

Beginning in August 2017, the Information Security team will be updating our mail filters to block additional potentially dangerous executable file types from reaching University mailboxes. We recognize that this may cause some disruption for email users, however we feel that the risk outweighs the end-user impact. 

Please note that if a file is blocked, the email will still be delivered and that attachment replaced with a text file with the following message "Dangerous file types are blocked for your protection. For any additional questions, please contact the administrator." If the file is required, please contact the CCS Help Centre for assistance (519) 824-4120 x58888 or 58888help@uoguelph.ca.

What file types are blocked by and cannot be opened by Outlook 2016?

File types blocked by Outlook 2016

Outlook 2016 prevents the opening of attachments with potentially unsafe file extensions by blocking nearly 100 different extensions. When you send an email containing an attachment which has a blocked file extension will receive the following message:

This item contains attachments that are potentially unsafe. Recipients using Microsoft Outlook may not be able to open these attachments. Do you want to send anyway?

Recipients using Microsoft Outlook to read an email which contains an attachment with a file extension that Outlook blocks will see the message that the file has been blocked at the top of the email.

Outlook blocked access to the following potentially unsafe attachments...

The CCS Information Security Team also has a list of file types that are blocked as attachments which may be different than the list of attachments blocked by Outlook.  When in doubt, check the Information Security list. The Information Security team uses a tool called IronPort which checks for and blocks incoming mail messages with a banned attachment.

What is my quota limit?

Your Gryph Mail email quota is 50 GB. Check out Your Gryph Mail Quota for information on how to check your quota, what will happen as the amount of quota that is being used approaches its limit, and steps you can take to ensure you don't go over your Gryph Mail quota.

What should I do if I go over quota?

Office 365 has three levels of quota, and it's only when you reach the last one that you can't receive any more mail.  The three levels are:
 

  1. Warning: Exchange will send you an e-mail telling you that your mailbox is almost full, and asking you to reduce your mailbox size.
  2. No send: at the next level, you will be unable to send any messages, but you can still receive mail. Again, you will receive messages from Exchange telling you what is happening.
  3. No send or receive: finally, as well as being unable to send messages, you will also be unable to receive them. Anyone trying to mail you will have their mail returned as ‘undeliverable’. Exchange will send you messages saying that your account has been ‘closed’: this does not mean you can’t log in and read or delete messages, it just means that you can’t send or receive mail.
