Multiple TS environment: Outlook 2010 Cached Exchange Mode
I know there are related threads but there was never a resolution to the question as far as i can tell and my scenario is different than the others:
We have two load balanced Citrix terminal servers running Server 2008r2 with Office 2010 installed. I want to enable Cached Exchange mode for the TS profiles. We use Desktop Authority (formerly ScriptLogic) to control most user settings based on what user
they are and what computer they are logging into. On both servers we have put in a SSD drive mapped as D: where we will be caching the OST files.
Through Desktop Authority i had set the default OST location and enabled cached exchange mode for a group of test users and it worked great when they first logged in. It cached where it needed to cache and all was well. But when that user logged off and
logged onto the other RDS server, their profiles would look for the OST on the server that is was first created on even though the default OST location was D: (independent of computer). I thought it would just recreate the OST on the new TS they were logging
into but it throws an error when launching outlook stating that it cannot find the OST becasue its looking for it on a "share" stored on the other TS.
Any thoughts or comments would be appreciated.
Hi,
In your scenario, I think this blog below will be helpful to you, you can try to change the .ost file location and check if this can be a fix:

Note: The article is written for Outlook 2013, but it also applies to Outlook 2010. The version of Outlook 2013 is 15.0, for Outlook 2010 it's 14.0.
Since I don't have Desktop Authority here, I'm not sure what settings it may control, you can contact their support to discuss this problem as well.

Hi,
I have Exchange 2013 setup in a new environment (no migration) and it is working great except I just realized there is a big problem.
I notice the following
Problem 1:
Outlook 2010 with sp2 with cached exchange mode on: when I import the pst into outlook, it imports fine but the sync is extremely slow. It uploads to the Exchange 2013 mail server at 20-70KB/sec (bytes) via LAN.
Problem 2:
Outlook 2010 with sp2 with cached exchange mode off: when I import the pst into outlook, it imports extremely slow. It uploads to the Exchange 2013 mail server at 20-70KB/sec (bytes) via LAN.
More info:
-user1 has 1GB of mail and when setting up the user on a new pc with outlook with cached exchange mode on, it downloads the mail very fast. It downloads at 40-80 Mbps/sec (bits).
-I have Exchange 2013 with CU3 with win2k12 non r2.
Why is the download so fast from Exchange 2013 but the upload to Exchange 2013 is extremely slow? How do I fix this?
ThanksI did some more testing.
I setup a test environment with:
-Exchange 2013 SP1 on win2k12 r2
-Outlook 2010 SP2 on windows 7 sp1
-Outlook 2010 SP2 on windows 8.1
-Outlook 2013 SP1 on windows 8.1
Both windows 7 and windows 8.1 have the very slow upload issue to Exchange 2013. Windows 7 upload to Exchange 2013 is around 20-70KB/sec (bytes) via LAN. Windows 8.1 upload is a bit more responsive at around 500-600KB/sec (bytes) via LAN.
I changed the TcpAckFrequency to 1 for windows 7 and 8.1 and the problem went away. The upload on both Windows 7 and 8.1 was going at megabytes after the change.
I hope Microsoft fixes this soon.
PowerShell script to have this automated via GPO:

Exchange 2010 & Outlook 2010 - Cached Mode "okay" work well for you?
Hi All,
On our Client Laptops/PCs we disabled cache mode a long time due to issues experienced with a combination Delegates and Cached Mode occasionally affecting Calendaring. We'd end up with vanishing appointments, etc.
What I'd like to know from you is if you've had a positive experience with Exchange 2010 & Outlook 2010 32bit. If you could impart any gotchas, etc. Our environment is fairly vanilla with a total of 1500 Users.
Thank you very much for your time,
Mr MisterHi,
I am using myself outlook 2007 over than WAN (VPN) connection with Exchange 2010 SP2 with about 3 GB mailbox and i personally have not faced any issues. Also, we have about 600 usres with more than 2 GB mailboxes using Outlook 2010 in online mode and
there are not many issues other than email with rich text format with screen shots attached in the mail body causing outlook hang. if we use the same email in html then no issues.
It all depends on the sizing of your CAS and mailbox servers and also on the NIC speed configured on the server. I personally feel that we should have NIC card set to 1GB on the servers also the backup and replication should be on seperate dedicated LAN. -
Use cached exchange mode for new and existing outlook profiles
Hi, I've noticed a difference in the behavior of this setting in Outlook 2010 vs 2013
In 2010, when the gpo is set, everything is greyed out for the user, but in 2013, the user can change the setting. Has anyone else noticed this? Is this something that MS decided to change or a bug?
I'll attach screenshots of the settings and the end result later.
joeblowHi,
à
In 2010, when the gpo is set, everything is greyed out for the user, but in 2013, the user can change the setting.
Based on your description, I understand that “Use Cached Exchange Mode” will gray out in Outlook 2010 when
set "Use Cached Exchange Mode for new and existing Outlook profiles".
However, in Outlook 2013, you will still be able to check “Use Cached Exchange Mode”. If anything I misunderstand, please don’t hesitate to let me know.
Just my guess, Office 2013 Administrative Templates may be a little difference with Office 2010 Administrative
Templates. On current situation, I suggest that you would post the question in
Office Forum. I believe we will get a better assistance there.
Hope this helps.
Best regards,

Why is an OST created even if Cached Exchange mode is disabled?
We have run into performance issues on our VDI environment which have been traced to Outlook. By default Cached Exchange Mode is enabled, this obviously creates an OST file. However, if this is disabled, either by GPO or in the registry and the OST file
is deleted, it creates another one anyway. The problem is we use non persistent with persona machines, so every time a user logs on it pulls a new machine, creates the OST in their persona then copies this OST to the C drive. This results in up to 10 minutes
between pulling the machine and being able to do anything.
Looking deeper into it there is another setting needed in the GPO or DWORD in the registry to not allow creation of an OST, see below
My question is why on earth is an OST created even if Cached Exchange mode is disabled? Why is this second setting even there? By definition if you are not using Cached Exchange mode, you do not need to have an OST so this just seems redundant and annoying.Hi,
Outlook has one Online mode but two offline modes: Exchange Cached mode and Offline Folders. Although Outlook 2013 doesn't use true offline folders, only cached mode, you need to disable offline folders along with cached mode to prevent it and older versions
of Outlook from creating an OST file for offline use.
I think it should work if you have applied the GPO, or the registry values below:
Important
This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the
registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry,
http://windows.microsoft.com/en-US/windows7/Back-up-the-registry
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\15.0\outlook\cached mode
DWORD: enable
Value: 0
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\OST
DWORD: NoOST
Value: 2
NoOst value specifies whether or not an OST is created at startup. Setting the
NoOst value to 2 will prevent the use of OST files. A value of 3 will allow OST files for cached mode but won't create one when online mode is used.
The explanation above is quoted from Diane Poremsky's article:

Long delay for add-in saving emails with Cached Exchange Mode off for one user's Exchange account
Hello,
Before I start, I have asked questions in the Outlook Developer forum and was referred here as it appears to be an Exchange Server problem that I am experiencing, not related to Outlook or the add-in that I am developing.
I am an Outlook developer with an Outlook add-in that adds MAPI properties to emails and then calls MailItem.Save to save the changes.
The add-in uses the Internet Message ID MAPI property for some functionality, so I have to turn turn Cached Exchange Mode off to ensure that my functionality works correctly for the Sent Items folder (otherwise no Message ID property exists).
This process works fine for 99% of users.
I have one particular user that has a huge delay (~1 minute) when MailItem.Save is called for items in his account. He is using an Exchange account. If I switch Cached Exchange Mode on there is no longer a delay (as no communication with Exchange Server). The
user does not have an excessively large Mailbox.
The problem is not caused by the network or communication path to the server as the problem exists on any computer where other users are ok.
I'm sure the problem is not caused by my add-in, but likely a problem with the user's Exchange account. Does anyone have any suggestions on how I may be able to resolve the delay and what might be causing it?
Thanks

Outlook 2010 cached mode cannot see GAL but Outlook 2007 can via Exchange 2010
Hi,
I have a problem similar to
this but with a different cause.
Our OAB config looks good from both Outlook 2007 and Outlook 2010. Both can see the GAL in non-cached mode but in cached mode only 2007 can see the GAL. In 2010 it's just not there. Even the same user can only see it in 2007.
Does anyone have any suggestions as to why this is?
Cheers,
RobHi,
I have got the same issue, that I can't see updated OAB in outlook 2010.
Can you share the detailed path of the locations you have mentioned here:
In Office 2010, this happens but these values also exist in the [Service1] section and are blank:
OfflineAddressBookPath=
OfflineFolderPathAndFilename=
And how do we add locations to these paths?
Thank you in advance. -
Outlook 2010 using Exchange 2010 - cannot send this item after updating draft email
I have a client who has the following setup.
SBS 2011 server (Exchange 2010) and a Windows 2008 R2 Terminal Server (with Office 2010 SP1 installed).
This particular user has a Windows XP PC with Office 2010 SP1 installed (joined to SBS 2011 domain).
This user creates a email at their office on their PC and saves it in draft to continue working on it when they get home.
At home they RDP into the terminal server and load outlook and start updating their saved (Draft) email. They then try to send it and the following error pops up. "Cannot send this item".
If they try to save the changes they have made it pops up with "The operation failed".
I have tried various settings all with the same results.
Office 2010, Office 2010 SP1, Online mode and Cache mode (on the Windows XP PC).
Any ideas?Hi Rajkumar,
OK. After further testing I have narrowed it down to the email signature?
If I save a draft email in Outlook on the Fat client (Windows XP + Office 2010), then go straight into Drafts folder and open the email and add one line of text and try to send or save again it fails.
If I don't have a signature, it works fine.
I currently trying to determine what part of the signature it doesn't like (it is quite a large signature, multiple images and a disclaimer etc). I'm having mixed results - I can remove the signature totally from the draft email and then it will save
or send fine.
Strange that it can save the email to Draft in the 1st place but doesn't like updating it a 2nd time???
I have also created a new outlook profile (online mode) with the same results. -
Hello,
We are running Exchange 2007 on our server and our user clients use Outlook 2010. One of my users is having the following issue. Whenever he opens Outlook 2010, it would crash and show this message: "Microsoft Outlook has stopped working. A problem
caused the program to stop working correctly. Please close the program". I tried recreating his Outlook profile and the issue persisted. I also tried to create his Outlook profile on a different computer and same message shows up. Both computers are domain
joined.
I checked Event Viewer both on his computer and the other computer I tried to set up his Outlook profile on. Both machines showed the same three error logs:

This leads me to believe the problem has to do with his Exchange User Mailbox account. But I have no clue what could it be. He is the only user experiencing this problem.
Any help is greatly appreciated!! Thanks!Hi,
Sorry for my delay. Have the issue been resolved?
If there are too many items in the problematic user's mailbox, please delete some and check whether the Outlook can be opened. Please uncheck Use Exchange Cached mode to use Online mode and confirm if the user can access the mailbox for Outlook.
Also try to connect to this user's maibox from your working machine with Outlook. Then check whether it works.

Free Busy takes over 30 seconds to retrieve on Outlook 2010 using Exchange Server 2010
We have a small 100 user domain running Exchange server 2010 and outlook 2010 clients. The issue is that Retrieving Free/Busy takes over 30 seconds.
So someone is trying to schedule a meeting has to wait Minutes see the Free/busy time for many users.. I have checked and all the users in question have published at least one month free busy time.
It seems it would be much faster. Anyone have this same experience and know of a way to speed it up?
thanks in Advance
DavidHi David,
Does the issue happen in OWA? In Exchange 2010, the free/busy information is retreved by using Availability service (EWS url). Generally, if a user wants to view free/busy information when create a meeting, the http Availability service request
would send to CAS server.
Please check whether the usage in Exchange server is high when the slow free/busy information occurs. This reflect time would also be related to the network in your environment.

Search in Outlook 2010 with Exchange Server 2010 doesn't work properly
Hi all,
I have a problem with a clients Exchange 2010. Search function in Outlook 2010 doesn't work properly, the employee can't search mails and contact - he doesn't get any result :-(
In application syslog/protocol I get this error:
Function 'CISearch::EcGetRowsetAndAccessor' found, content indexing for database 'Mailbox Database 0139257080' caused by MSSearch-Error '0x80041820' deactivated
Can anybody help me with this, if its necessary I can give further information :-)

Thomas DeinertHi,
What’s Exchange Version? Sometimes, after Installing Exchange 2010 SP 1, Searching via OWA or Outlook Online Mode may Fail. If so, please try the following solution:
Download the script
Repair-ExchangeSearchSymlinks.ps1 from the Script Center.
Copy the Repair-ExchangeSearchSymlinks.ps1 script to the Scripts directory on the Mailbox server (default installation is C:\Program Files\Microsoft\Exchange Server\v14\Scripts).
On the afflicted Mailbox server, open the Exchange Management Shell by right-clicking the shortcut and selecting “Run as Administrator”.
Within the Exchange Management Shell, navigate to the Exchange Scripts directory.
Within the Exchange Management Shell, run the following script: .\Repair-ExchangeSearchSymlinks.ps1
Within the Exchange Management Shell, run the following script (without the symbols [] and substitute the database name(s) for any databases you wish to reset: .\ResetSearchIndex.ps1 [-force] <dbname> [<dbname>]...
You will receive an Event ID 109 when the rebuilding of the index starts for each database and an Event ID 110 for each database when the index rebuild has completed.
After receiving Event ID 110 for each database, test to make sure search functions correctly with both OWA and Outlook operating in Online Mode.

Outlook 2010 / SBS2011 Exchange Emails being deleted when moved to another mailbox
Hi All,
I have an SBS2011 std, using exchange 2010
User A has full access permission to mailboxes B and C
In Outlook 2010 they have the additional mailboxes visible automatically (ie. not via the "more settings" tab in outlook set up)
Recently when user moves a message from their inbox A, into a folder of the other mailbox B or C, or the inbox of that user, the message is very quickly deleted, and ends up having to be recovered from the "recover deleted items" section of the
users Deleted Folder.
(Hope that makes sense)
Previously I understand they were able to move emails in this way, between mailboxes.
Can anyone confirm if this should a) be possible and b) what might have changed or be going wrong?
The server was patched and rebooted last night to try and fix the issue but it is still continuing.
Thanks,
JJHi,
Does this issue happen to a certain user or all users in the environment?
What if we just move emails within the same mailbox, will this issue continues?
How did the user move the emails? If they moved by dragging/dropping, please try right clicking the email and select Move > Other Folder...
If this issue only happen to certain user, I'd recommend you
create a new mail profile for that use and then test again.
In addition, do you have any antivirus software installed? If so, please disable the antivirus integration with Outlook to check the result. See:

Outlook 2010 to Exchange 2010 connectivity problem
We have a single Exchange 2010 server running DB, CAS, and HT this lives at our Corp HQ. We have 12 offices connected across MPLS and 2 offices connected across a Metro-e 100mb connection. We have had this environment in place for almost 2 years with no
issues.
Today in the office connected across the 100mb metro-e connection had a momentary network hiccup where all uses lost data momentarily. Connectivity to data and network resources restore immediately, but after that time, none of those users could
connect to Outlook 2010. When they try to connect outlook times out with an error that it cannot connect to the server.
I can ping the exchange server by name and ip. Response times are less than 7ms. Utilization on that connection is less than 10%. DNS is resolving.
Users can connect to OWA and get access to email.
The problem is only happening in only the one office. All other remote sites are functioning fine.
Users can access all other network resources with no issues, including OWA and Intranet/Internet sites both HTTP and HTTPS.
I believe that it may be something is blocking the RPC connection. If I try to run the Connection which also fails to connect.
I have rebooted the Exchange server
I have rebooted the local DC in the remote office with the problem. Also reset DNS. And on clients tried flush/register DNS.
No server changes have been made on any of the servers involved.
Only changes taken place prior to the network "hiccup" happening was network admins implemented QOS on the routers to give priority to SIP/voice traffic. According to them, this will have no impact on other data.
Any ideas or suggestions on next steps for troubleshooting?Hi
Did you they not make any routing changes? Can you ask them to check that all ports for exchange are open and also ask them if they made any other changes?

In Outlook 2010/MS Exchange, can't search shared contacts
Have had MS Outlook 2010 for quite some time, and I really like it. However, since I got a new computer, I'm not able to search the contacts of my 2 bosses. Since my one boss has over 1700 contacts, I really need the ability to search his contacts back!
What happens is even if I am in Jon's contacts, it jumps to my contacts to do the search
From Outlook 2010 - File - Open - Other User's Folder - I do press enter when i've typed in the person/company i'm looking for.
Help desk guys have told me it is a compatability issue with Outlook 2010 - which sounds stupid to me since I had no problem till i got a new computerHi,
I have done a test on my lab machine and the search result was pretty good.
Please make sure the Outlook version is up to date. Try switching the Outlook to Online Mode and check if the issue persists.
You can also try rebuilding the Outlook Profiles and run Outlook in Safe Mode by:
1. On the Start menu, click Run.
2. Input "Outlook.exe /safe" (without the quotation marks) and click OK.
Note: There is a space between Outlook and the forward slash (/).
3. Please check if the issue persist.
