The following Powershell script tests a connection to Outlook.

$sw = [System.Diagnostics.Stopwatch]::StartNew()

$outlook = [Runtime.Interopservices.Marshal]::GetActiveObject('Outlook.Application') 

$selection = $outlook.ActiveExplorer().Selection[1]


$convo = $selection.GetConversation()
$convo.ConversationID

$root = $convo.GetRootItems()

$sw.Stop()

$sw.Elapsed

[System.Threading.Thread]::CurrentThread.ApartmentState

To run this script, do the following:
1. Open Microsoft Outlook and select an email.
2. Open PowerShell_ISE on your computer then click on File > New. Paste this script into the tab that appears and then press F5.

When you run this script, it should complete nearly instantaneously and should show results similar to the following:

If the script takes a long time to execute or returns errors, then this likely means that there is a problem with your Outlook or mailbox configuration. To resolve that issue, we recommend contacting your IT company and performing the steps below:
1. Remove and re-add your mailbox from Outlook. Then retest.
2. Uninstall and reinstall the latest version of Outlook. Then retest.
