When I click on the "Email by Google" link from Mosaic, my browser goes to a Google page and when I try to sign in, I get an error message saying I can not log in.

This happens occasionally. The browser should never redirect to a Google page. Your log in page should be a McMaster page with the official logo and the address should end in Should you be redirected to a google page, you must clear your cache, temporary files and cookies in your browser. Once complete, you will be directed to the proper web page for log in

When I log into the account, I cannot log in the first time, but the second time I am successful. Why is this happening?

If you are accessing the log in page from a bookmark that was created from the login page, you will have problems of this type. The solution is to go to, and bookmark this page. This bookmark will work properly. Bookmarks that are created from the actual log in page itself will cause a double log in problem.

I cannot receive mail sent to my McMaster account, but I can send from it.

Your primary email in Mosaic is set to an account other than your McMaster account and all mail will go there, and bypass your McMaster email account completely. To make sure all of your mail goes to your McMaster email account, log into Mosaic, click on MAC ID and Email Management, then make your McMaster account your primary account. Changes to this will take effect the next day.

What about my primary account in Mosaic?

The primary account in Mosaic is set by the student and is the default account to which all McMaster e-mail addressed to wil be sent. Upon activation of your Studentmail, students' primary email account will be automatically set to their McMaster account.

What's included in Google Apps at McMaster?

Email account with 25GB of storage, Google Calendar and Google Docs. Any additional Google apps may be rolled out as they become supported.

I already have a personal Gmail account. Do I still need a Google Apps at McMaster account?

Yes. Personal Gmail accounts are different than your Google Apps at McMaster account. Your Google Apps at McMaster email account is now the primary email address and the official means of communication between the University and you.

What about Patriot Act?

Privacy impact assessment (PIA) has been conducted and filed with the McMaster University Secretariat. The Canadian Privacy Commissioner's office has stated that privacy risks from the US Patriot Act are no greater than the risks from domestic or other foreign law enforcement bodies. If you wish to get a copy of the PIA feel free to officially request it from the University Secretariat.

I am a retiree from the University, will my email be affected.

Will I be effected if I am a part time student as well as a full time employee at McMaster?
