Create Profiles for Managing Microsoft Exchange using Windows Terminal (Online and On-Prem)

Image
I use Windows Terminal a lot and I wanted to show off how I setup Exchange Management profiles to make my life easier. Enjoy! Exchange Online: In Windows Terminal, go to "Settings" and click "Add a new profile" at the bottom. Give it a name you like, and in the "Command line" field, Paste the following: powershell.exe -NoExit -Command "Import-Module ExchangeOnlineManagement; Connect-ExchangeOnline -UserPrincipalName user@contoso.com"  Make sure to replace the UserPrincipalName property with your own. On-Prem Exchange: In Windows Terminal, go to "Settings" and click "Add a new profile" at the bottom. Give it a name you like, and in the "Command line" field, Paste the following: powershell.exe -NoExit -Command "$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://exchange.domain.com/powershell/; Import-PSSession $Session -DisableNameChecking"  Make sure to replace the Connecti...

Give a User 'SendAs' permssions to a Mail-Enabled AD Group in Exchange Online

Image
Really specific situation I know, but this took me an embarrassing amount of time to figure out. Thankfully, its pretty simple. Just use the 'RecipientPermission' cmdlets: Add-RecipientPermission -Identity GROUP -Trustee USERNAME -AccessRights SendAs Where GROUP is the 'samAccountName' or 'Primary Email' of the group you want to allow the user to send as and USERNAME is the 'samAccountName' of the user.

Get a User's Active Directory Groups

Problem: You need to list out a User's AD Groups quickly and in a way you can copy and paste them. Solution: So we can use the Get-ADUser cmlet with the "Properties" parameter specifying "Member Of" to get a list of AD Groups. The issue is the groups are formatted as distinguished names which are not very easy to read. PS C:\Users\jheisler> (Get-ADUser -Identity "jheisler" -Properties "MemberOf").MemberOf CN=ITTeam,OU=O365,DC=johnjheisler,DC=com CN=ACL-ITDevOps,OU=Security Groups,OU=Groups,DC=johnjheisler,DC=com Thankfully, All we need to do to overcome this is pipe the Get-ADUser cmdlet into a Get-ADGroup cmdlet. Then we can specify the "Name" property off the AD Group objects. PS C:\Users\jheisler> ((Get-ADUser -Identity "jheisler" -Properties "MemberOf").memberof | Get-ADGroup).Name ITTeam ACL_ITDevOps That's it. A quick and clean way to list a user's AD Groups. https://github.com/Snowstuff123/Po...
