What you’re seeing
- Mail on the phone stops updating at a certain point and shows 'Cannot Get Mail' or an account error.
- The phone keeps prompting for the password, even after it is entered correctly.
- Calendar and contacts stop syncing along with email.
- Mail still works on the computer and in a web browser.
- A message saying the device has been quarantined or blocked by the organization.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The password changed, and the phone's mail app is still trying the old one.
- The organization moved to modern authentication or MFA, and the phone's built-in mail app or account profile still uses an older sign-in method.
- A conditional access or mobile device policy now requires the phone to be enrolled or compliant.
- The device was blocked or quarantined in Exchange or Google Workspace after repeated failed attempts or by an admin rule.
- Battery-saving settings or background restrictions stop the mail app from syncing.
Why it matters
Many employees rely on their phone for email when away from their desks. When syncing stops, urgent messages from clients and coworkers go unseen, and people may not realize they're behind until something is missed. Repeated failed sign-ins from a phone holding an old password can lock the user's account entirely, cutting them off on every device. Workarounds like forwarding mail to personal accounts create security and compliance problems.

Frequently asked questions
Will the user lose any emails?
No. The mail stays on the server and will appear once the phone reconnects.
Does the phone need to be enrolled in management?
That depends on your company's security policies. We explain in plain English what your policy requires and why before making changes.
Can this be resolved without the phone in hand?
Server-side causes can be resolved remotely; the user may need to tap through a sign-in or approve a prompt on the phone during the session.
