  Importing Global Address List entries into a user’s Contacts folder Steve Goodman  /  February 20, 2012 I had a fairly unusual request from one of my customers whilst performing the final stages of an Exchange migration. A while ago, the CEO wasn’t able to lookup people to contact from the Global Address List due to connectivity problems and wanted “offline” access to the GAL from his phone. The customer asked me if it would be possible for me to write a little script to effectively grab the GAL (they aren’t a massive company) and copy it into the CEO’s mailbox, into a dedicated Contacts folder, for example “OrgContacts”. Whilst certainly not a great idea for a larger company, for a few hundred users it’s not a bad idea, and in a previous post I’ve  written something very similar , so in my spare time put together the following script… What it does: Connects to the user mailbox using EWS as a the logged on Administrator, using impersonation.

Some of relatively common and difficult issues we see in support are related to client connectivity to Exchange.  There are several variations that we classify as connectivity (related to server performance or otherwise).  They can include: Clients prompting for credentials (intermittently or continuously) Clients getting disconnected Clients are unable to establish a connection Clients freezing or going unresponsive ActiveSync clients experience delays receiving new mail There are many factors that can contribute to these symptoms, and each one can lead down a completely different troubleshooting path. In this post we will focus on methods and tools to troubleshoot these. There are too many potential underlying causes to cover them all but hopefully this will serve as a
