Q - I did everything according to the admin guide. Followed the correct order for permissions in exchange, checked the com+ identity etc. etc. still when I use step 2 the application crashes and gives Access Denied and step 3 gives messages about certificates and all...
A - log on as Administrator and open Exchange System manager.
Browse to the Mailbox Store and do Properties - Security to locate the Exchange Domain Servers group in the list.
Check if in the list of permissions you see a Black tick
in the DENY column for Send As or Receive As. If so remove that
Q - I did everything according to the admin guide and everything looks good, I can create group calendars, connect users to them and get a green box when I share their calendars in step #3.. still nothing appears in the groupcalendars.
A - Try this : Start - Run: regsvr32
B - (ex2k3) Open the Mailbox store where the
users have the mailboxes and open the Mailboxes object to list all mailboxes
The quickest way to fix a missing SystemMailbox
object is to create a new mailbox store. After that move the user mailboxes from
the old to the new store.
Q - I see duplicates in the groupcalendar for recurring items.
A - Update to version 1.4.16 and find a new setting in config.ini
Q - It's not working at all ....
#1: Call or email us. it's the fastest method for you to resolve the problem. For us.. we like to hear about problems so we can prevent them in future versions.
#2: Try the following
Did you reboot the server? If not, do that first.
Please start the troubleshooting quest with one user only. Do all steps hereunder.. no shortcuts please.
log on to the exchange server with gcadmin account
go to step #2 and select the test user (jack)
go to step #3
open the com+ service manager until you see the ExchGC component on the right pane.
see the "ball in the box" with the plus sign on it ? Is it running? If it is, right click and shut it down.
Keep an eye on the ball and now create an item in the test-user's personal calendar
Look at the ball again... It should be turning in the box and stop after one minute if no other users create items.
If it's still not working, enable logging in the gcadmin tool. Close and open the gcadmin tool, create an item in a personal calendar and send the gcadmin errorlog + eventlog + errorlog to firstname.lastname@example.org
Q - It works for some but not for all users.
A1 - Make sure that the users where it does not
work realy use the calendar that is part of their Exchange Inbox folders. Some
users enter calendar information in a PST file calendar and Exchange server
can't get to that.
A3 - When sharing users in step 3 works ok but some of your users don't get their items replicated to the groupcalendars.... AND you have multiple mailbox stores, check if all mailbox stores have a system mailbox. If the problem is a missing system mailbox (ref:http://support.microsoft.com/kb/316622 ) you may see that all users in one mailbox are working correctly while the users in the other stores don't trigger the com+ component at all. No error log or event log will be created either.
Q - It worked for "a year" and suddenly it stopped working!
A3 - If you changed the password for the gcadmin account, make sure to adjust it as well for the com+ component in component services.
A4 - If you installed a new file level server virus scanner or adjusted the settings, make sure that it does not scan any exchange server directories.
A5 - make sure that the 'Send As' permissions are in place for the gcadmin account. (admin guide, step B)
A6 - If you changed the default email policy of the exchange server.. delete the old exchange name from the config.ini file
A7 - Call or email us. Include your log files as an attachment please.
Q - Can't see all recurring items in outlook 2003 cached mode favorites folder. (outlook bug)
We use Outlook 2003 SP2 with Microsoft Exchange 2000 SP3 and in order to add the group calendars to my Other Calendars section on the Outlook Calendar view I must first browse the Folders tree, right-click the chosen Calendar and select the Add to
A - After
disabling the 'Download Public Folder Favorites' in Cached Exchange Mode
Settings section on the Advanced tab of the email account properties this now
works fine - you can still leave 'Use Cached Exchange Mode' enabled though.
here's a tutorial http://www.msexchange.org/tutorials/Configuring_Outlook_2003_for_Offline_Use.html
Q - Can't use blanks for calendar names.
A1 - Workaround 1 ; Use underscores for blanks ie _
A2 - log on to Outlook with the gcadmin account and create the public calendar folder with the name you need under the groupcalendar root folder.
Q - Runtime error: '-2147016656 (80072030)': Automation Error. There is no such subject on the server
A - The GCADMIN account is not a member of the exchange domain servers group. (admin guide step B)
Q - error: -2146105340 Unknown Error or -2146105340 Method '~' of object '~' failed
A - Known to be raised when the default email

A - Delete the Exchgc com+ component from
Component services - computers - my computer and run the MSI installer from the
Q - The default location of the groupcalendar root folder can't be used in our organization. We have access to one subfolder only. (we can not access the 'All public folders' root but only our company subfolder called 'CompanyX')
A1 - To work around this problem do the following:
1- log on to a workstation with the gcadmin
account and connect outlook to the exchange server.
Q - GCAdmin.exe starts with an error.
A1 - You might be running it on a test server.
Run it on the real Exchange server or set up a test server with a separate organization and dns.
Q - error numbers in the error logs
A1 - error -2147217895 or -2147024891
A2 - error -2141913011
Q - Nothing appears in the group calendars (after creating a new item in my calendar I don't see it on the GroupCalendars)
A1 - Remove the account you are using to start the COM+ component from the Exchange server objects and add it again using these steps:
A2 - Check the Exchange Alias of the user who's appointments are not being displayed. Change the alias into the partial email address that comes before the '@' sign. (if email address = JJackson@domain.com, make the exchange alias: JJackson) and try again.
A3 - If the com+ component (exchGC) ball starts turning
in response to the creation of an item in a personal calendar but nothing
in the group calendars: Enable error logging on the first page of the gcadmin
Q - Items appear in the group calendars but they don't disappear or duplicates appear.
A1 - Grant the account you are using to start the COM+ component full access to the Public Folder Group Calendars.
Q - Appointments with a slash in the subject are being ignored. They don't show on the group calendar.
A - A confirmed bug. This was fixed in version 1.312
Q - On initial testing we had setup some group calendars with test names. Now we're trying to setup calendars with real names (some the same as the test names). The problem we're having is that users are still linked to the old calendars, even though I've used the admin tool to stop their sharing and disconnected the mappings.
A1 - You deleted the calendar folders before you un-mapped them from the users in step #2. It is very simple to fix this.
- in the gcadmin.exe tool select the user in step#2. The tool will offer you to remove the incorrect calendar mapping from this user.
Q - Hidden items still show up when the body of an appointment contains @@@
A1 - Open gcadmin.exe step #1 - General settings. Remove the checkmark of the first option, close the form and reopen to check the option again. (this bug was fixed in the current version)
Q - Error in step #1 when creating the root folder or Group Calendars.
A1 - Make sure that the gcadmin account you are
logged on with has all user rights.
Q - Error in step #2 when connecting a user to a Group Calendar.
A1 - Make sure that the gcadmin account you are
logged on with has all user rights and is not restricted by local/domain
policies which prevents it from writing and reading values from the Active
Directory. A simple test is to open Users & Computers, Open a user object
and change the value of the DESCRIPTION field. If this fails the GCADMIN account
Q - Error message when trying to enable calendar sharing for a user (step#3) (7 possible answers)
A1 - Confirm that you installed the Com+ component (ExchGC) in component manager and make sure the identity and password are set to use the GCADMIN account. (note: NEVER right click and START the component manually. This will prevent it from working correctly)
A2 - Check the user account of the user that you try to enable sharing for. The 'Exchange Alias' or 'short name' must be the same as the email address part that comes before the @ sign.
A3 - Make sure you are logged on with the gcadmin account to the Exchange console.
A4 - Confirm that the users mailbox is on the same Exchange server as the one you logged on to.
A5 - On Exchange 2003 there might be something else causing problems. To check this, try to restart the "COM+ Event System" service in the services control panel. If the service refuses to stop and times out with an error try the following:
- In control panel - Add/Remove programs, uninstall the ExchGC component.
- Reboot the server.
- Try to restart the "COM+ Event System" service in the services control panel. This should work fine now.
- Install the .MSI file from the setup Zip file you downloaded from this website.
- Configure the Com+ component (ExchGC) in the Component Manager with the GCADMIN account and password.
A6 - Check the Com+ component. If the 'ball with plus sign' is spinning in its box, right click the component and shut it down. Try again to share a user calendar.
A7 - If the solutions above all fail, there might be a restriction (deny) on the the "Administrators" or "Exchange Domain Servers" group to access users mailboxes and calendars. In that case remove the gcadmin account from those groups and make sure that the gcadmin account has been granted access to all mailboxes and Public Folders as described in step C of the administrator guide.
Q - Errors when you try to install the MSI file of the Com+ application
