RPC Client Access Throttling Logging

By default, you have to use PerfMon counters to see how often throttling is occurring for RPC connections.

However, there is a way to have this information "properly" logged. To achieve this, modify the Microsoft.Exchange.RpcClientAccess.Service.exe.config file located in \Program File\Microsoft\Exchange Server\V14\Bin and add Throttling to the LoggingTag string so it looks like this:
<add key=”LoggingTag” value=”ConnectDisconnect, Logon, Failures, ApplicationData, Warnings, Throttling”/>

Now restart the RPC Client Access service and you will see this information in logs created in the “\Program Files\Microsoft\Exchange Server\V14\Logging\RPC Client Access” folder. When throttling happens, you will usually find the keyword “exceeded”.

This way, you can easily see when RPC Throttling kicks in, what it is doing and why!

Office 365 Portal Login Error on Mobile Devices

Since early this week that whenever I try to login to an Office 365 “wave 15” tenant on a mobile device I get the following error message:

I have tried from an Android mobile phone and iPad, always with the same result...

I know for a fact that Microsoft is looking into this at the moment.

As a workaround, if you go to:
  • https://tenant_domain.sharepoint.com


you will be able to login directly to OWA or SharePoint. However, this from an iPad as from my android phone I get the error: “the page contains too many server redirects”...

I will update this post when I get more new on this.

Exchange 2013 Data Loss Prevention

Data Loss Prevention [DLP] is a system designed to detect a potential data breach/leakage incident in a timely manner and prevent it. When this happens, sensitive data such as personal/company information, credit card details, social security numbers, etc., is disclosed to unauthorized users either with malicious intent or by mistake. This has always been an important matter for most companies as the loss of sensitive data can be very damaging for a business. For many years now, there have been both software and hardware solutions that monitor data while:
in-use: end-user actions such as copying data to USB or printing it for example;
in-motion: network communications like e-mail, web traffic, Instant Messaging, etc.;
at-rest: data stored in file shares or on users’ drives.

Up until now, Exchange Administrators had to rely on 3rd-party solutions to achieve this, but some solutions would cause more harm than good and user productivity would suffer. With Exchange 2013, Microsoft now makes it possible to enforce compliance requirements for such data and control how it is used in e-mail. DLP is the new feature that allows administrators to manage sensitive data in Exchange!

Default Junk E-Mail folder moved to a subfolder of Journal

A while back got a user saying he wasn’t receiving some e-mails. Straight away I asked for an example and searched the Message Tracking Logs for the e-mail, only to confirm it had been delivered.
Luckily for me, my search revealed something really useful too:

MessageLatency : 00:00:00.9060000
MessageLatencyType : EndToEnd
EventData : {[MailboxDatabaseName, mdb33], [DatabaseHealth, -1]}


The e-mail was delivered to the Junk E-mail folder (look at RecipientStatus)! :) Ok, job done! Not exactly... When I went to the user’s mailbox to check a couple of e-mails to see if they were actually Spam, I couldn’t find the Junk E-mail folder! For some strange reason, it got moved to inside the Notes folder!...



So, how do we move it back?! If you try to move any of the default folders like Inbox, Deleted Items, etc., you will simply receive an error message.
The only way to move these is to use MFCMapi:
1. Download MFCMAPI
2. Launch MFCMAPI
3. Go to Session -> Logon and Display Store Table
4. Select the outlook profile of the user and double-click “Mailbox - User Name”
5. Expand “Root Container”
6. Expand “Top of Information Store”
7. Locate Junk E-mail, right click it and select Copy
8. Highlight “Top of Information Store”, right click it and select Paste
9. Click OK
10. Check “COPY_SUBFOLDERS” and “FOLDER_MOVE” and click OK

Hope this helps!
