   • Go to admin.microsoft.com
   • Select appropriate plan
   • Enter organization details

2. Configure Domain:

1. Add your domain (e.g., company.com)
2. Verify domain ownership via DNS TXT record
3. Update MX records (keep Google MX for now)
4. Add SPF, DKIM, DMARC records

DNS Records to Add:

# Verification Record
TXT @ MS=ms12345678

# SPF Record (combined)
TXT @ "v=spf1 include:_spf.google.com include:spf.protection.outlook.com ~all"

# DKIM for Microsoft 365
CNAME selector1._domainkey selector1-company-com._domainkey.protection.outlook.com
CNAME selector2._domainkey selector2-company-com._domainkey.protection.outlook.com

# MX Records (switch after migration)
MX @ company-com.mail.protection.outlook.com (Priority 0)

Step 2: Create User Accounts

Option A: Manual Creation (Small businesses)

1. Admin Center → Users → Active Users → Add User
2. Enter user details
3. Assign licenses
4. Set up email

Option B: Bulk Import (Recommended for 10+ users)

john.doe@company.com,John,Doe,John Doe,Manager,Sales,US,STANDARDPACK
jane.smith@company.com,Jane,Smith,Jane Smith,Director,Marketing,US,STANDARDPACK

Import via PowerShell:

# Connect to Microsoft 365
Connect-MsolService

# Import users from CSV
$users = Import-Csv -Path "C:\users.csv"

foreach ($user in $users) {
    New-MsolUser `
        -UserPrincipalName $user.UserName `
        -FirstName $user.FirstName `
        -LastName $user.LastName `
        -DisplayName $user.DisplayName `

Common Challenges and Solutions

Challenge 1: Email Migration Failures

Symptoms:

• Emails not migrating
• Partial mailbox migration
• Error messages in migration logs

Solutions:

# Check migration errors
Get-MigrationUser | Get-MigrationUserStatistics | 
    Where-Object {$_.Status -eq "Failed"} |
    Select-Object Identity, ErrorSummary

# Common fixes:
1. Verify IMAP is enabled in Gmail
2. Check app passwords are correct
3. Increase throttling limits
4. Retry migration for failed users

Challenge 2: Large Mailboxes (50GB+)

Solutions:

• Split migration into multiple batches
• Use incremental migration (migrate in stages)
• Consider archiving old emails before migration
• Upgrade to Microsoft 365 E3 (100GB mailbox)

Pre-Migration Cleanup:

Gmail → Search: "older_than:2y"
→ Archive or delete old emails
→ Reduces migration time by 40-60%

Challenge 3: Google Docs Conversion Issues

Common Issues:

• Formatting lost in conversion
• Complex formulas breaking
• Embedded content missing

Solutions:

1. Test conversions first (pilot sample)
2. Keep originals for reference (30-day overlap)
3. Manual conversion for critical documents
4. Use Google Drive for desktop (keep as Google Docs)

Conversion Tool:

# Install clasp (Google Apps Script CLI)
npm install -g @google/clasp

# Convert Google Docs to Office formats
clasp login
clasp export --format docx

Challenge 4: User Resistance

Symptoms:

• Low adoption rates
• Complaints about new system
• Requests to switch back

Solutions:

• Communicate benefits clearly (better integration, desktop apps)
• Provide extensive training (multiple sessions)
• Designate "champions" (early adopters to help others)
• Create comparison guides (Gmail → Outlook equivalent features)
• Offer extended support (dedicated help for first month)

Challenge 5: Broken Integrations

Common Issues:

• Third-party apps expecting Gmail API
• Calendar sync apps failing
• CRM integrations breaking

Solutions:

1. Audit integrations before migration
2. Find Microsoft 365 equivalents (e.g., Zapier connectors)
3. Update API configurations (switch to Microsoft Graph API)
4. Test integrations in pilot phase

Update Integration Examples:

// OLD: Gmail API
const gmail = google.gmail({version: 'v1', auth});

// NEW: Microsoft Graph API
const client = Client.init({
  authProvider: (done) => {
    done(null, accessToken);
  }
});
