Display date on Outlook items in Drafts Folder

​If you need to see the date items were added to the drafts folder, you will need to use a custom view and add modified date field to the view and sort by it

So follow these steps to add modified date to othe view

  1. Right click on the row of field names at the top of the message list, were it reads "Arrange By: Date"
  2. Choose View Settings (Outlook 2010) or Custom (Outlook 2007 and older)
  3. Click the Columns (or Fields) button to open the Show Columns dialog
  4. Select date/Time fields from the "Select available columns from" menu
  5. Click on modified and Add to add it to the view then close the dialog

Working with Recoverable Items Folder

​The Recoverable Items folder (known in earlier versions of Exchange as the dumpster) exists to protect from accidental or malicious deletions and to facilitate discovery efforts commonly undertaken before or during litigation or investigations

To retrieve the following quota settings:

* RecoverableItemsQuota
◦ RecoverableItemsWarningQuota
◦ ProhibitSendQuota
◦ ProhibitSendReceiveQuota
◦ UseDatabaseQuotaDefaults
◦ RetainDeletedItemsFor
◦ UseDatabaseRetentionDefaults
use this one liner:
 
Get-Mailbox "testmbox" | Format-List RecoverableItemsQuota, RecoverableItemsWarningQuota, ProhibitSendQuota, ProhibitSendReceiveQuota, UseDatabaseQuotaDefaults, RetainDeletedItemsFor, UseDatabaseRetentionDefaults
 
2.To retrieve the current size of the Recoverable items folder:
Get-MailboxFolderStatistics "testmbox" -FolderScope RecoverableItems | Format-List Name,FolderAndSubfolderSize
 
please note that quota for recoverable items folder can be raised.The default is 30GB
 
To make sure no items are deleted from the Recoverable Items folder, increase the Recoverable Items quota. You can also increase the Recoverable Items warning quota, and set the deleted item retention period to a value higher than the current size of the user's Recoverable Items folder. This is particularly important for preserving messages for mailboxes placed on In-Place Hold or litigation hold. It's recommended to raise these settings to twice their current size.
 
3. Increase recoverable items quota
 
Set-Mailbox "testmbox" -RecoverableItemsQuota 80Gb -RecoverableItemsWarningQuota 80Gb -RetainDeletedItemsFor 3650 -ProhibitSendQuota 80Gb -ProhibitSendRecieveQuota 80Gb -UseDatabaseQuotaDefaults $false -UseDatabaseRetentionDefaults $false
 
 

4. This example retrieves the size of the Recoverable Items folder and its subfolders and an item count in the folder and each subfolder.
Get-MailboxFolderStatistics -Identity "Mickey Mouse" -FolderScope RecoverableItems | Format-Table Name,FolderAndSubfolderSize,ItemsInFolderAndSubfolders -Auto

Search IIS logs for ActiveSync data for specific user accounts.

Scenario: You want to find ActiveSync activity for specific users that is stored in IIS logs on the Exchange Servers.
 
Using LogParser you can edit and run the following command:
 
logparser "Select * from '\\servername\c$\inetpub\logs\logfiles\w3svc1\*.log' Where cs-uri-stem LIKE '%Microsoft-Server-ActiveSync%' AND (cs-uri-query LIKE '%username1%' OR cs-uri-query LIKE '%username2%')" -i:IISW3C -q:on >\\FilePath\filename.txt

HTTP 413 Errors in IIS logs with ActiveSync and Certificate Based Authentication

Scenario: After setting up Certificate Based Authentication for ActiveSync, users on mobile devices may experience the following error message: "Cannot Send Mail.The message was rejected by the server because it is too large". When you check the IIS logs, you may see HTTP 413 errors. Our Environment: Exchange 2013, Windows Server 2012, IIS 8.0.
Reason: The client connection was dropped to prevent DeadLock. The server requests renegotiation for certificate authentication, and the content length the client is trying to send is larger than the value of the UploadReadAheadSizemetabase property in IIS.
WorkAround: The workaround below will re-bind the certificate to enable client certificate negotiation upfront.
Re-bind the certificate and enable ClientCertNegotiation:
1. netsh http show sslcert <-- Copy the results to notepad.
2. netsh http delete sslcert hostnameport=<hostnameport>:443
3. netsh http add sslcert hostnameport=<hostname>:443 certhash=<certhash> appid=<appid> certstorename=MY clientcertnegotiation=enable <-- Use copied results from step 1 to fill in these values)
Note: We have a separate IIS Site with EAS setup for Certificate Based Authentication. We use a separate certificate on this site so we can enable clientcertnegotiation on the certificate. Another work around would be to change the UploadReadAheadSize on the Web Server, the website that hosts the EAS subsite, and the EAS subsite.

something went wrong UserHasNoMailboxException

Issue: Customer couldn't access office 365 mailbox using the unified URL and kept getting "something went wrong, user has nomailboxexception" errors.

Notes: Customer was running hybrid configuration with Office 365 and Exchange 2013. Also the mailbox is a remote mailbox

Resolution: TargetOWAURL for the organization relationship at customer site was
outlook.com/owa/servicedomain.edu
Issue was resolved when customer modified remote routing address of the remote mailbox to user@servicedomain.edu
The service domain in the target OWA url needs to match the remote routing address of the remote mailbox

Exporting Mailbox to a PST File

​Exporting mailbox to a PST File
Note: Must have the "Mailbox Import Export" role assigned
 
From powershell, type New-MailboxExportRequest -mailbox testmbox -name -filepath\\servername\pstfiles\testmbox.pst

This will export all folders and data in each and export it into the specified PST file. Also note that the dumpster will also be exported by default.
If you want to get additional details about the mailbox export request, you can use the Get-MailboxExportRequest or Get-MailboxExportRequestStatistics cmdlet.
 
if the export fails to complete, you can add -baditemlimit for eg
 
New-MailboxExportRequest -mailbox testmbox -name -filepath\\servername\pstfiles\testmbox.pst -baditemlimit 50
