What it does
Automatically removes guest access from Microsoft Teams channels 30 days after project completion or contract end date, protecting sensitive information and maintaining compliance without IT manually auditing permissions.
Why I recommend it
Guest access accumulates over time as contractors, partners, and vendors come and go. Manual access reviews are tedious and often skipped, creating security risks. Automated cleanup keeps your Teams environment secure and compliant.
Expected benefits
- Reduced security risk from stale guest access
- Compliance with data access policies
- 5-10 hours saved quarterly on access audits
- Clean Teams environment with only active collaborators
How it works
Monitor project management system or CRM for project completion -> wait 30 days -> query Microsoft Graph API for guest users in associated Teams channel -> remove guest access -> notify IT security team -> log removal for audit trail.
Quick start
Export current Teams guest list and manually review who should still have access. Create a spreadsheet of projects and their guest users. When projects close, set calendar reminders for 30 days later to manually remove access.
Level-up version
Integrate with project management (ClickUp, Asana) to auto-detect project closure. Send warning email to guest 7 days before removal with option to request extension. Create exceptions for long-term partners. Generate quarterly access reports for security team.
Tools you can use
Collaboration: Microsoft Teams
Project management: ClickUp, Asana, Monday.com, Jira
Automation: Power Automate, Zapier, Make
Security: Microsoft Graph API for access control
Also works with
Workspace: Slack for guest management
PM tools: Basecamp, Smartsheet for project tracking
Identity: Azure AD, Okta for centralized access management
Technical implementation solution
- No-code: Power Automate scheduled flow -> check ClickUp for completed projects -> if >30 days past completion -> list Teams guests via Graph API -> remove guest role -> log to SharePoint.
- API-based: Scheduled function -> query project system for closed projects -> Graph API list Team members -> filter guests added before completion date -> remove guest access via Graph API -> send summary email to IT.
Where it gets tricky
Handling edge cases where guests need extended access, coordinating across multiple teams and channels, avoiding removal of long-term vendor partners, and maintaining audit logs for compliance requirements.
