+
+  
+
+## Exchange Module Won't Load
+
+  
+
+Check if installed:
+
+  
+
+```powershell
+
+Get-Module ExchangeOnlineManagement -ListAvailable
+
+```
+
+  
+
+Check execution policy:
+
+  
+
+```powershell
+
+Get-ExecutionPolicy -List
+
+```
+
+  
+
+Enable script execution:
+
+  
+
+```powershell
+
+Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+```
+
+  
+
+---
+
+  
+
+## Exchange Commands Hang
+
+  
+
+Test connection:
+
+  
+
+```powershell
+
+Get-ConnectionInformation
+
+```
+
+  
+
+Test response:
+
+  
+
+```powershell
+
+Get-Mailbox -ResultSize 5
+
+```
+
+  
+
+Avoid pulling everything:
+
+  
+
+✅ Faster
+
+  
+
+```powershell
+
+Get-Recipient -Filter "DisplayName -like '*FSM*'"
+
+```
+
+  
+
+❌ Slower
+
+  
+
+```powershell
+
+Get-Recipient -ResultSize Unlimited |
+
+Where-Object {$_.DisplayName -like "*FSM*"}
+
+```
