First, login to your tenant via Powershell using Microsoft’s new Exchange V2 Powershell module.

We’re going to be using the Get-InboxRule commandlet. If you run it outright, you’ll see a limited list of Inbox rules across your tenant. To narrow things down, you can use Get-InboxRule -Mailbox [user] to get rules for a specific user. Using the -Identity parameter will not work for this! Identity is for specifying specific Inbox rules. You can use wildcards, so you could do Get-InboxRule -Mailbox jeff*

The results will be:

From here, you can use the -Identity parameter to get information on specific rules such as their date of creation, what they actually do, and more!

Using Microsoft’s recently released Exchange Online PowerShell V2 Module, we can easily find IMAP and POP from mailboxes in Office365 via Powershell.

Finding IMAP and POP Mailboxes, Powershell V2:

Get-EXOCASMailbox -Filter {IMAPEnabled -eq $True -or POPEnabled -eq $True}

If you’d like to disable, take a look at my next post about doing that!

I wrote this quick and dirty one-liner to help monitor and find stuck emails in Exchange / Office365 mailboxes across a tenant and export the list as a CSV.

Get-Mailbox -ResultSize Unlimited | Get-MailboxFolderStatistics | Where-Object {$_.Name -eq "Outbox" -and $_.ItemsInFolder -gt '0' } | Select-Object Identity, FolderType, ItemsinFolder, FolderSize | Export-CSV "C:\CSVs\Outbox.csv"

To disable Clutter in Office365 via Powershell, simply do the following:

Connect to Office365 Powershell for your account

Then simply run this command to disable Clutter for all mailboxes:

Get-Mailbox | Set-Clutter –enable $false

That’s it! If you want to disable Clutter for a single mailbox, you can do the following:

Set-clutter -identity user@email.com-Enable $false

To do this via the Office365 Portal, just navigate to: Mail > Automatic Processing > Clutter and turn it off!

First you need to connect to Office365.

Next, simply run this commandlet:
Add-MailboxFolderPermission calendar@company.com:\Calendar –User guy@company.com –AccessRights Author

Your accessrights options are: Owner, PublishingEditor, Editor, PublishingAuthor, Author, NonEditingAuthor, Reviewer, Contributor, AvailabilityOnly, LimitedDetails

If you’d like to get permissions, you can simply use:
Get-MailboxFolderPermission –Identity calendar@company.com:\Calendar –User guy@company.com

Finally, to remove permissions:

Remove–MailboxFolderPermission –Identity calendar@company:\calendar –user dude@company.com
