What's Happening
You're trying to log into CMIS, but the two-factor authentication (2FA) code isn't arriving in your email. Before contacting CMIS support, this issue is often caused by problems with your email provider—not with CMIS.
When Microsoft 365, Google Workspace, or other email services experience outages, you won't receive authentication codes even though CMIS is sending them successfully.
First Steps: Check Your Email Service
Before calling CMIS support, verify your email service is working:
- Check if you can receive ANY emails - Send yourself a test email from another account. If that doesn't arrive, the problem is with your email service.
- Verify your email service status:
- Microsoft 365: Visit status.office.com or office365status.com
- Google Workspace: Check Google Workspace Status Dashboard
- Other providers: Search "[your email provider] status" or contact your IT department
- Check your spam/junk folder - Sometimes 2FA emails get filtered incorrectly.
- Verify your inbox isn't full - A full mailbox will reject new messages, including authentication codes.
Why This Happens
CMIS sends your authentication code immediately when you request it. However, we rely on your email provider to deliver it to your inbox. When services like Microsoft 365 or Google experience outages—even brief ones—you won't receive the code even though CMIS sent it successfully.
Recent example: On Thursday January 22, 2026, Microsoft 365 experienced a widespread outage affecting many public agencies and construction management firms. During this time, CMIS was operating normally and sending codes as expected, but users couldn't receive them due to the Microsoft service disruption.
What You Can Do
Immediate solutions:
- Wait and retry - If your email provider is experiencing an outage, wait 15-30 minutes and try logging in again once service is restored.
- Contact your IT department - They may be able to confirm email service issues or restore access more quickly.
- Check the status page - Your email provider's status page will show active incidents and estimated resolution times.
Long-term preparation:
- Bookmark your email provider's status page - Know where to check first when you experience login issues.
- Keep your account information current - Ensure your email address in CMIS is accurate and actively monitored.
- Document the process - Share this article with your team so everyone knows to check email service status first.
When to Contact CMIS Support
Contact CMIS support if:
- Your email service is confirmed working (you're receiving other emails)
- You've checked spam/junk folders
- You've waited at least 15 minutes and requested a new code
- Your inbox has available storage space
We're here to help with CMIS-related issues, but we cannot resolve email service outages from external providers.
