When attempting to access the main M365 webapps page you may see a "m365-copilot-app.m365copilot.errorPageTitle" Error preventing access to the typical way of accessing the M365 suite online. We've found that accessing the apps directly still work. 

Microsoft is aware of the issue and working to resolve to it.

You find direct links to the common webapps here:

Outlook
Word
Excel
PowerPoint
OneDrive

Additionally, you may Go through myWestern > Email > Top right profile pic - "View Account" > “My Apps” to view all apps.
