SSL Error: “The security certificate presented by this website was not issued by a trusted certificate authority.”

Installing a 3rd party SSL Certificate can be very frustrating, tedious process and things can go haywire unexpectedly. Have you tried re-keying/generating the Certificate Signing Request (CSR) then installing the SSL Certificate many times and was wondering why your server is rejecting it? I have experienced this annoying process and will not go through with this process again.

I found a great utility to alleviate my irritation in installing a SSL Certificate. DigiCert is a one stop shop to do repair, test and export your SSL certificate.

When you download DigiCertUtil simply open up the compressed file (DigiCertUtil.zip) and double-click on the executable file (DigiCertUtil.exe) then you’ll see the list of all the Certificates, some with the yellow exclamation mark or a red X.

Now that you are aware on how to troubleshoot your SSL Certificate by using a DigiCert utility, this great utility will save you a lot of work and headaches. I’m quite impressed with the outcome.

There’s a neat tool in Exchange Server 2010 that you may utilize in case a company phone (e.g. Droid, iPhone, etc) has been misplaced, lost or stolen. You may perform a remote wipe of the data from the mobile phone from Exchange Server without having to do a physical mobile data wipe out.

On Exchange Management Console, expand Microsoft Exchange On Premises, expand Recipient Configuration, click on Mailbox, from the Actions pane, select the Mobile User that you wish to do a remote data wipe out, click on Manage Mobile Phone…

Editing Information Store’s Cache thru ADSIEDIT.msc

Issue: In the Processes Tab of Task Manager, store.exe’s physical memory is allocating too much memory.

Resolution: You may tweak the cache size of the Exchange Server’s Information Store to prevent the store.exe’s physical memory size to increase. To do this process, click on Start button and type ADSIEDIT.msc, press enter.

Navigate to the Configuration> CN=Services> CN=Microsoft Exchange> CN= First Organization> CN=Administrative Groups> CN=Exchange Administrative Groups> CN=Servers [SERVERNAME]> > InformationStore

Right click Information Store and set the following to 72000 then Click OK to save the setting.
MsExchESEParamCacheSizeMax
MsExchESEParamCacheSizeMin

If adjusting the cache size didn’t help to resolve the issue, verify that the Exchange Server has the latest Service Packs and Window Updates.
