The Office365 button in myDMACC takes me into one of my Office365 apps (like Webmail) instead of the Office365 home screen.

To change your Office 365 landing page to the Office 365 home page, please do the following:

When you're in Office 365, you'll see your initials in the upper right corner of the screen.

1.  Click your initials and select My Account.

2.  Click Settings on the left side of the page.

3.  A menu will slide out from the right side of the page. Select Start Page and choose your preferred page from the drop-down menu.

4.  Click Save
