Many Thanks microtom…
I had the same issue for months. I have to use webmail until last week, for whatever reason, the issue resolved itself, and I was able to connect to the microsoft exchange server. I did not make any changes to the setting nor the exchange server. The only difference was I have just upgraded my internet capacity.
by the way, the link to the guide does not take me to the guide.
Certificates.. I hate them! :) thanks for sharing Kris! Add me on BF3: microtom ;)
Got the problem fixed in my setup. Had nothing to do with an Exchange Address Book (which simply doesn’t even have a service on my server). Problem turned out to be related to certification.
I wrote a small guide on how I fixed it here: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_27995660.html#a38783217
Hello Enrico
You need to start it on the Exchange Server, not the client.
Greetings, Tom
Hello Enrico
What Version of Exchange are you running?
Greetings, Tom
Kris, do you have any Exchange Services that are configured to “Automatic” and are not running?
Can you help me get to the Microsoft Address Book?
I keep getting a message that Outlook 2010 exchange is unavailable. I tried right-clicking on computer in Windows 7 to get to the Microsoft Exchange Address Book like was suggested, but I don’t know where to go from there to fix the issue.
Got the same error here with Outlook 2007 clients and an Exchange 2013 server. Our server, however, does not have a service named “Microsoft Exchange Address Book”
Hello Veronica, are you looking on the Exchange Server? what version of Exchange is running? Greetings, Tom
I have the same issue as Roshini, I cannot find “Microsoft Exchange Address Book” from Manage services
Dude, read again ;) You need to open the Services console using the run command. You can alternatively use right click on my computer and select “manage”.
Start -> Run -> Services.msc -> Click on “Microsoft Exchange Address Book” -> Click the “Start” button
@Roshni
I cannot find “Microsoft Exchange Address Book” in run command :(
I had a problem that my Outlook 2010 ‘Reply all’ button wasn’t working and showing the same error message from the taskbar. Starting the Address Book service, also fixed this issue. Thank you for sharing!
I second that, thank you, thank you, thank you.
Hello,
Just to thank you, thank you, thank you.
