Fixing Server Error in ‘/owa’ Application Error

Ran into this one today… and it is  nothing you want to see happen on an Exchange server! I was re-assigning services to a new SSL certificate when I started getting this error. After doing some searching, I found the easy fix from Microsoft. Under Server Config > Client Access, you can click Reset Virtual Directories on the far right. From there, you can choose which directories to rebuild (OWA, Autodiscover, etc.) Doing that fixed my issue for OWA!

Sharepoint Error – User Not in Directory

Had an odd one today. An internal user with permissions to a Sharepoint site was getting the error “user not in directory”. Searching Google comes up with many different options and reasons for this error, but no concise cause / solution.

The user was able to login to Office365 webmail normally without any errors and was had a Sharepoint license for several weeks and hadn’t reset their password recently.

Eventually, I had the user un-invited and then re-invited and it worked!

MailboxImportRequest Fails

I ran into an issue with a Powershell script I wrote recently, where I received this error:

The name must be unique per mailbox. There isn’t a default name available for a new request owned by mailbox xyz

Basically, a record is kept for completed mailbox move requests, and if you do too many for one mailbox, you get the above error. Don’t worry! Just run the following command in PS to clear away the completed request records, and you’ll then be able to run the import request!

 

Get-MailboxImportRequest -Status Completed | Remove-MailboxImportRequest

That’s it!

How To: Disable Clutter in Office365

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!

How to Find Last Logon Time for Exchange Mailbox Users

The last logon time of an Exchange 2010/2013/2016 mailbox user can easily be found by running the Get-MailboxStatistics cmdlet in the Exchange Management Shell.

 

You can further sort the info by including and running the following command:

Get-MailboxStatistics -Server EXCH | Sort LastLogonTime -Descending

And export it to a CSV by adding an Export-CSV option like below:

Get-MailboxStatistics -Server EXCH | Sort LastLogonTime -Descending | Export-CSV c:\lastlogon.csv
