Can someone help me with following code to increase/faster outlook VBA Macro Speed ? Currently It taking lot of time run all email rules and getting process slow.

Sub RunAllInboxRules()
Dim st As Outlook.Store
Dim myRules As Outlook.Rules
Dim rl As Outlook.Rule
Dim count As Integer
Dim ruleList As String
'On Error Resume Next

' get default store (where rules live)
Set st = Application.Session.DefaultStore
' get rules
Set myRules = st.GetRules

' iterate all the rules
For Each rl In myRules
' determine if it's an Inbox rule
If rl.RuleType = olRuleReceive Then
' if so, run it
rl.Execute ShowProgress:=True
count = count + 1
ruleList = ruleList & vbCrLf & rl.Name
End If

' tell the user what you did
ruleList = "These rules were executed against the Inbox: " & vbCrLf & ruleList
MsgBox ruleList, vbInformation, "Macro: RunAllInboxRules"

Set rl = Nothing
Set st = Nothing
Set myRules = Nothing
End Sub

In general the performace is better if you forego the progress dialog. Instead, simply display a MsgBox when done. Also, joining the rulelist string could take one or more seconds for 1000 loops. Since you run all rules, why not just say that instead of listing all the rule names?
