Exchange 2010 Calendar & invite time issue

I have started getting complaints from some users indicating that when they accept calendar invites, they sometimes are out of sync by an hour. Normally, when you look at two users calendars, you are looking at it in your timezone, and as such, any meetings
or invites that you have in common would appear on the same line.
What we see is in some cases, they are an hour apart, and it does not seem to matter if both people are in the same time zone or a different one. In one case, one user is in MST and the other is in EST, in another, both are in MST, and when I look at two
users calendars that are showing hte issue, I can see it and I'm in CST. I have also looked at the calendars in OWA, so it does appear to be something server-side.
It also does not appear to be all the time. Sometimes they will go through properly, and other times, they come through wrong. Sometimes when the organizer updates the meeting and sends the update, it fixes it on the other person's calendar.
I've looked around and there oare other similar issues, one of which indicated installing KB2863058 and rebooting the server fixed it, but that KB is applied on my server (Was applied in September), and while it may or may not be installed on the clients
that are affected, near as I can tell, that KB has no effect on US time zones, so that *shouldn't* be causing this.
I've also read about multiple copies of CDO.DLL causing it, but the only copy was found in 'C:\Program Files (x86)\ExchangeMapi' (I have BES 5 on the server, although technically, I could remove it if not needed as no one is using Blackberries any more).
There are a bunch of 'cdosys.dll' and 'cdosys.dll.mui. All of the 'cdosys.dll' have a modified date of 6/6/2012 with two sized: one for the 64-bit version and one for the 32-bit version.
Has anyone seen this kind of issue before? Any thoughts to a cause and resolution?

Hi,
Do all the calendar invites show incorrect times or some specific ones?
As what Ed says, please
check the time, time zone and daylight savings time
settings
respectively in Windows
Control Panel’s Date and Time applet of all computers, OWA settings,
Outlook Options. Make sure that they are the same values. Also check whether the invites are sent by the same organizer.
If all configurations are proper, please create a new calendar invites respectively in OWA and Outlook. Then send it to the problematic users to check whether the issue persists.
Thanks,

Outlook 2013 / Exchange 2010 Calendar Invitations blank on recipient side

We have Exchange 2010 and Outlook 2013 for our clients. When our users send calendar invitations to external recipients, some of the recipients are receiving regular emails just containing the notes field and subject. Specifically, when we email
a @hotmail.com or @outlook.com address this occurs. However, when we send an external calendar invitation to @gmail.com, the recipient can see it as a calendar invite and reply with an accept/tentative/decline.

How is everything so far?

Exchange 2010 calendar not showing on outlook 11 Mac

Since this question is about a Microsoft product, you might have more luck getting suggestions if you ask in Microsoft's own forums.

Exchange 2010 calendar sharing issues

I am getting several reports of users not being able to open a calendar shared to them by their manager. I have checked the calendar permissions on their managers computer which all look like they are able to read it.
The manager is using Outlook 2013 to share out her calendar. the users are using various avenues, either on an iPad or through OWA. I'm at a loss of where to check for additional issues on this. Any suggestions or ideas for you brilliant people?

Outlook 2013/Exchange 2010 Free/Busy access issues.

Good Day Everyone,
I am running a Win 2008 R2 environment with Win7 users, using Exchange 2010 and Outlook 2013. Last week my users started experiencing issues with being able to view Free/Busy in the Calendar for any other user. I have checked past issues with this with patches
KB 2837618 and KB 2837643. Neither patch is showing as installed and I have tried a nummber of the suggested fixes offered for that issue to no avail. OWA seems to be working just fine.
Our Outlook version is: 15.0.4605.1003
I need a fix for Outlook users and since I havve 140 users, individual fixes are a not realistic option.
Any assistance would be greatly appreciated.

Hi,
Please test if Out of Office feature works well in Outlook. If Out of Office doesn't work either, it should be Autodiscover related.
Once Autodiscover has not been configured properly, the Free/Busy information may not display correctly. If you are also seeing issues with Out of Office assistant, we may assume that you haven’t correctly setup Autodiscover, since these two symtoms are
common when Autodiscover is not configured correctly.
To verify that, please test Outlook Autodiscover Connectivity:

Exchange 2010 ambiguous URL'S issue while coexist with exchange 2013

Hi ,
Please correct me if i am wrong and also all of you tell me your valuable suggestions.
Like as said in the below article we are having an exchange 2010 ambiguous url's in place.
Referred
article :
http://blogs.technet.com/b/exchange/archive/2013/05/23/ambiguous-urls-and-their-effect-on-exchange-2010-to-exchange-2013-migrations.aspx
As said in this article, if we have exchange 2010 ambiguous url's in place we will face issues during exchange 2013 coexistence.I agree with that point .
Question : On such case why don't we use a separate namespace for internal and external outlook anywhere settings in exchange 2013 which is different from cas array name and also there is no need to disturb the existing exchange 2010
environment by changing the rpc client access attribute in exchange 2010 databases or by forcing the exchange 2010 internal outlook clients to connect via OA. Please clarify my doubt and say whether the mentioned scenario is possible or not ?
Note : Same time please consider the new namespace which is going to be utilized on exchange 2013 outlook anywhere settings is available on SAN certificate.

How can I display my MS Outlook/Exchange 2010 Calendar events on my web application's calendar?

I'm building a web (client) application (built in html/JavaScript/jQuery) that has a built-in calendar. I would like to pull in my Outlook/Exchange Calendar events
and display them in my web application's calendar. What is the best way to do that from a JavaScript/jQuery environment? I've been searching all over for plugins or examples of how to talk to Exchange/Outlook and retrieve Calendar events but I haven't found
a solution yet. We are currently using MS Office/Outlook/Exchange 2010. I don't need to modify the calendar events, just read them. (Note that I can't use an OWA Web Parts link
to display the calendar in an iframe; I need to have access to the actual event data so I can include other UI elements that I need for my application.) Thanks
in advance for the help!

Hi,
There's an old Java API for EWS, and you can access EWS with direct soap request to retrieve the data you want.

Exchange 2010 DAG netowrk replications issues - Causing database copies to be disconnected and resynchronizing.

My
environment is as follows.<o:p></o:p>
We have 3 exchange 2010 servers.<o:p></o:p>
EX1, EX2, DREX1. All servers are exchange 2010 14.2 build 247.5<o:p></o:p>
EX1 and EX2 have two nics, one LAN and one for BACKUP <o:p></o:p>
The dag is configured to to communicate to all three.<o:p></o:p>
The IP for EX1 is 192.168.100.51 - LAN, switch A; 160.100.3.51 - BACKUP, switch B<o:p></o:p>
The IP for EX2 is 192.168.100.52 - LAN, switch A; 160.100.3.52 - BACKUP, switch B<o:p></o:p>
DREX1 is located in another network. It is in another building connected via vpn. The ip
for DREX1 is 192.170.100.51. There is no BACKUP network for this server<o:p></o:p>
(These are not the actual address, but the concept is similar)<o:p></o:p>
The dag network configuration is as follows.<o:p></o:p>
DAGNetworkDR has a subnet of 192.170.100.0/24; Network Interface of 192.170.100.51<o:p></o:p>
DAGNetwork01 (LAN) has a subnet of 192.168.100.0/24; Network Interfaces of 192.168.100.51
and 192.168.100.52<o:p></o:p>
DAGNetwork02 (BACKUP) has a subnet of 160.100.3.0/24; Network Interfaces of
160.100.3.51 and 160.100.3.52<o:p></o:p>
Last Friday, 3/7/14 something happened.<o:p></o:p>
To lead up to that, I noticed the issue because we have DPM 2010 making 15minute express
full backups of our exchange databases when I reviewed the backup jobs, the
exchange database backups using dpm2010 failed all weekend long starting at
11:00pm that Friday.<o:p></o:p>
The issue that occurred was that the database copies went to a status of Disconnected and
Resynchronizing, and after about 30 seconds, the status would show
Resynchronizing.<o:p></o:p>
All attempts to resolve this with the research methods failed. Deleting the
logs and reseeding failed, suspending, then rebuilding failed.<o:p></o:p>
Creating a new database worked, creating a database copy worked, but seeding the copy
failed. All with the same pattern, a status of Disconnected and
Resynchronizing, and after about 30 seconds, and the status would show
Resynchronizing.<o:p></o:p>
The database was mounted on EX2, and seeding to EX1
DREX1 has no issues.<o:p></o:p>
All the DAG networks were in a good status, all Green and all up. I could ping from
EX1 to EX2 and from EX2 to EX1 on both networks fine.<o:p></o:p>
In the middle of the week, about 3/12/14, we resolved the issue. We rebooted EX1, no
fix, but after rebooting EX2, it all resolved. It did a fail over to DREX1. I think it failed to do the failover to EX1. However, when it came back up, it was happy, it was reseeding slowly. After about an hour and a half, it
was all healthy.<o:p></o:p>
We thought it was all good EXCEPT, on Friday night at 11:00pmish on 3/14/14, the same
issue occurred; a status of Disconnected and Resynchronizing, and after about
30 seconds, the status would show Resynchronizing.<o:p></o:p>
The database was mounted on EX2 and seeding to EX1 again. I did not notice the
issue until I performed my review of the backup jobs again on Monday.<o:p></o:p>
Late Monday morning, my boss and I were looking at more articles, but all the same results,
delete the database copy and reseed. Which we knew would not work.<o:p></o:p>
I mentioned that it was strange because the networks were all up. What made us try the next
scenarios was just "luck" I guess. I made a statement about not remembering
which networks DAG replication took place over. Again, we have a LAN and
a BACKUP network. Bother were listed to use replication, so we decided to
disable replication over the BACKUP network in the EMC. Immediately, the
database copies switch to healthy and started seeding.<o:p></o:p>
Later that evening I enabled replication over the BACKUP network and it failed again with
a status of Disconnected and Resynchronizing, and after about 30 seconds, the
status would show Resynchronizing. I disabled the replication over the
BACKUP network and the database copy went back to healthy<o:p></o:p>
The last round of windows updates were pushed to these boxes the Friday before the
issues began, 2/28/14. I don't believe the updates to be the issue. <o:p></o:p>
Can anyone make any suggestions as to where to look? It worked with the BACKUP
network enabled to so long that is eluding me as to why the issues would start
all of a sudden. I am also confident that the switch configuration for the
BACKUP network has not been changed at all in at least 2-3 months. I am
still open to look at the config. Please help if you can.<o:p></o:p>
<o:p></o:p>
Lastly, this is more of a monitoring thing, if anyone can suggest a good way to monitor
the database copies so that I can be alerted when the status changes. We
use WhatsUpGold 16.2 to monitor the devices. <o:p></o:p>
Thanks for any future assistance.<o:p></o:p>

You don't have to enable the Replication on Backup Network.
You should collapse your DAG network.

Exchange 2010 /hosting shared mailbox issue

Hello everyone.
I had an issue come up in our Exchange 2010 with /hosting switch deployment (currently at SP2).
We have several organizations and shared mailboxes configured and working on some. We add Full access permissions via Powershell + Send as rights and it auto configures and works just fine.
Last week though, one of several people that uses a specific shared mailbox started getting the error: "Unable to open your default e-mail folders. The Microsoft Exchange Server computer is not available. Either there are network problems or the
Microsoft Exchange Server computer is down for maintenance." (Error ID: 300)
The other users can still work just fine. Configuring the account in another PC shows the same problem (so it's not the local profile).
Creating 2 users, giving nr1 full access to nr2 generates the same error.
In another org though, i was able to give full access to another acount to an existing user and it worked (although the auto-mapping didn't, had to add it manually)
I'm out of ideias. Any sugestions?
EDIT: Did a couple more tests on another Org. On this one everything works with the shared folder access with old and new accounts but strangely the auto-mapping doesn't.
It seems that this is an issue with the mapping.

Hi,
From your description, I recommend you manually update or create your Outlook profile with RPC encryption and check the result. Here is the steps on Outlook 2007 for your reference:
1. Select your profile, and then click Properties, click E-mail Accounts.
2. Select the Microsoft Exchange Server account, and then click Change.
3. In the dialog box that contains your mailbox server and user name, click More Settings.
4. In the Microsoft Exchange Server dialog box, click the Security tab.
5. Click to select the Encrypt data between Microsoft Office Outlook and Microsoft Exchange check box, and then click OK.
6. Click Next, and then click Finish.
For more information, here is a kb for your reference.

Exchange 2010 SP3 RU5 automapping issue - fixed in later RU?

Current Level: Exchange 2010 SP3 RU1
I'm planning on updating to RU8v2 but discovered
this thread indicating issues with RU5 + automapping + Office 2010 SP1. I couldn't find anyone reporting that the later RUs introduced the same issue or fixed it. So I'm just looking for anyone that may have experience with updating
past RU5 and still running Outlook 2010 SP1, did you see the same behavior with automapped mailboxes?

That should have been done last October

Exchange 2010 SP3 startdagservermaintenance.ps1 issues

My Environment is as follows:
Production
Server 1 - CAS, Hub Transport (DAG witness server)
Server 2 - Mailbox (3 databases - DAG with Server 3) - Currently at SP1
DR Site
Server 3 - Mailbox, Hub Transport
I have Exchange 2010 SP3 applied to server 1 and 3. I have not been able to successfully run
StartDagServerMaintenance.ps1 on Server 2. If I am ok with downtime, is there any risk in upgrading my server without running this script? If so, would I need to power off Server 1 and 3 first? I believe my issue with the script may
be due to a journal mailbox.

I assume you are talking about Updating Mailbox Server or you are just testing the script?
No you don't have to shutdown the server.
About the script, its suggestion to run it, but even if you are not running its ok.
By the way, how you are running the script? Are you running from the location where the script is residing.

Exactly. Break this down into discrete items.
Also what build of Outlook? Is that patched?
http://blogs.technet.com/b/rmilne/archive/2013/07/18/patching-exchange-don-t-overlook-outlook.aspx
And While Exchange 2010 SP2 is supported, you are well behind where I would like to see you. For a start you are missing several security updates in Exchange that can only be resolved by installing a newer RU

Exchange 2010 calendar meetings - allows meeting to be sent then sends decline message

We updated from Exchange 2003 to 2010 last year and are still trying to figure out how to make the resource rooms work properly. In 2003, if you tried to schedule a meeting and the room was not available, it would not let you send the request.
2010 does and then sends back a decline message. Can this be changed to be like 2003?

Is there not a way to have Outlook reject the meeting before sending it (like exchange 2003 did)? I know you can see this in scheduling assistant but not all users use that unfortunately....they just type in the names and send. Before
in Exchange 2003, it would check availability before sending and NOT send the meeting at all if the room was not available. That is what I would like to get back to.
Nope. Not possible in Exchange 2010 or 2013 using the built-in Exchange Calendar Asst features. Direct-booking is not recommended and Outlook 2010 and above do not allow it by default.
That is by design, allowing the server to manage and handle the meeting request logic.
The reason being is that there is now built-in delegate moderation, in-policy and out of policy requirements etc... The resource mailbox has no way of knowing if the meeting request meets or fails the requirements without receiving it first.
