Environment
U-M Slack (Enterprise Grid)
Issue
I can't log in to U-M Slack. I get an error: "Your email address is already registered to a deactivated account and cannot be reused. Please contact your Organization Admins for assistance."
Note: If you receive the following error message - "You are not eligible for the service requested" - you are not eligible to be a member in U-M Slack with your @umich.edu email address based on your current affiliation at the university. However, you can become a guest with a non-@umich.edu email address. Refer to
Eligibility for U-M Slack for more details.

Additional Information
This error occurs when the following five conditions are met:
- You were previously eligible for U-M Slack.
- You were a member of U-M Slack.
- You lost all eligible roles at the university (e.g., graduated, retired, quit, had a lapse in active student status such as changing programs, etc.).
- Your U-M Slack account was deactivated because you no longer held an eligible role at the university.
- You became eligible for U-M Slack again because your role at the university changed (e.g., started a new program, became employed, got sponsored by a department, etc).
Accounts are automatically deactivated upon role change at the university. They are automatically reactivated when a role change occurs but this process may take up to 24 hours.
