# 2026-06-12 — Lamaddux Calendar Sharing Fix (Jim ↔ Leeann)

## User
- **User:** Mike Swanson (mike)
- **Machine:** Mikes-MacBook-Air
- **Role:** admin

## Session Summary

The session addressed calendar sharing issues between users jim@jparkinsonaz.com and leeann@lamaddux.com on lamaddux.com. The error "Calendar sharing is not available with the following entries because of permission settings on your network" was traced to an Exchange sharing policy misconfiguration. Although both users reside in the same tenant (2f0c4c92-c608-4ee0-bdc2-87d5fd8fe929), the policy did not recognize jparkinsonaz.com as an internal domain. PowerShell scripts were developed to resolve this. The first script, fix-lamaddux-calendar-sharing.ps1, updated the sharing policy to include both domains. A second script, fix-lamaddux-calendar-delegation.ps1, was created to use direct delegate permissions as a workaround. Additionally, an automation issue was encountered with the remediation-tool on macOS due to a missing PyJWT dependency in the externally managed Python environment.

## Key Decisions

- Implemented PowerShell scripts to update Exchange sharing policies rather than attempting automated remediation-tool execution
- Applied direct delegate permissions as a workaround for sharing restrictions
- Created two solution paths: policy fix (recommended long-term) vs delegate permissions (immediate workaround)
- Deferred PyJWT installation to preserve system Python environment integrity

## Problems Encountered

- Exchange sharing policy did not recognize jparkinsonaz.com as internal domain despite both users being in same tenant
- Calendar sharing failed with "permission settings on your network" error when Jim attempted to share with Leeann
- Remediation-tool automation blocked by missing PyJWT dependency on macOS externally-managed Python environment (pip install blocked)
- Homebrew package `pyjwt` not available (suggested `pywhat` instead), preventing automated token acquisition

## Configuration Changes

### Files Created
- `tmp/fix-lamaddux-calendar-sharing.ps1` — PowerShell script to update tenant sharing policy
- `tmp/fix-lamaddux-calendar-delegation.ps1` — PowerShell script for direct calendar delegation workaround

### Files Modified
- None (solutions not yet executed by user)

- **Custom Domains:** lamaddux.com (primary), jparkinsonaz.com (verified custom domain)
- **Users:**
  - jim@jparkinsonaz.com — Exchange Online Plan 1, object ID 387dc966-fd91-4512-9b0f-d80b125769f4

## Commands & Outputs

### Attempted Token Acquisition (Failed)
```bash
export VAULT_ROOT_ENV="/Users/azcomputerguru/vault" && \
cd /Users/azcomputerguru/.claude/skills/remediation-tool && \
bash scripts/get-token.sh 2f0c4c92-c608-4ee0-bdc2-87d5fd8fe929 investigator-exo
```
**Error:** `ERROR: PyJWT not installed (pip install PyJWT cryptography)`

### Python Package Installation Attempts
```bash
python3 -m pip install --quiet PyJWT cryptography
```
**Error:** `error: externally-managed-environment` (macOS Homebrew Python restriction)

```bash
brew install pyjwt
```
**Error:** `No available formula with the name "pyjwt". Did you mean pywhat?`

### PowerShell Solution Scripts Created

**Script 1: Policy Fix (Recommended)**
Location: `tmp/fix-lamaddux-calendar-sharing.ps1`
- Updates default sharing policy
- Adds both domains with `CalendarSharingFreeBusyReviewer` permission
- Command: `Set-SharingPolicy -Identity $policy.Name -Domains @{Add='lamaddux.com:CalendarSharingFreeBusyReviewer','jparkinsonaz.com:CalendarSharingFreeBusyReviewer'}`

**Script 2: Delegation Workaround**
Location: `tmp/fix-lamaddux-calendar-delegation.ps1`
- Grants direct mailbox folder permission
- Command: `Add-MailboxFolderPermission -Identity "jim@jparkinsonaz.com:\Calendar" -User "leeann@lamaddux.com" -AccessRights Reviewer`
- Bypasses sharing policy entirely

## Pending / Incomplete Tasks

1. **User to execute PowerShell fix** — Mike needs to run one of the provided scripts:
   - Recommended: `tmp/fix-lamaddux-calendar-sharing.ps1` (long-term policy fix)
   - Alternative: `tmp/fix-lamaddux-calendar-delegation.ps1` (immediate workaround)
2. **Verify calendar sharing works** — After script execution, Jim should close/reopen Outlook and retry sharing
3. **Resolve PyJWT dependency** — For future remediation-tool automation:
   - Option A: Create venv for remediation-tool
   - Option B: Install via system package manager if available
   - Option C: Document manual PowerShell workflow as standard for Exchange policy changes
4. **Graduate tmp/ scripts** — If PowerShell approach becomes standard, consider moving scripts to `clients/lamaddux/scripts/` or `projects/msp-tools/remediation-tool/scripts/`
