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.

Hi,

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,

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:
http://community.spiceworks.com/topic/571571-outlook-slow-after-migrating-to-exchange-2013
PowerShell Script:
$strGUIDS=[array](Get-WmiObject win32_networkadapter -filter "netconnectionstatus = 2" | select -expand GUID)
foreach ($strGUID in $strGUIDS) {New-ItemProperty -path HKLM:\System\CurrentControlSet\services\Tcpip\Parameters\Interfaces\$strGUID -propertytype DWORD -name TcpAckFrequency -value 1} -
We recently migrated from Office 2010 to Office 2013. An annoying change is Outlook's "Use Cached Exchange Mode" setting that changes the previous setting of all email to partial email based on how old emails are. This is confusing
for end users because if they have a 1GB mailbox size limit and they look at the properties of their mailbox, it shows the cached amount which is always then less than the full amount. While they have a 1GB limit, the properties of their mailbox
might say 700MB because that's all that is cached, but meanwhile they can't send because they are actually over 1GB on the server side.
I want to set this cache setting to "All" for EXISTING profiles and new profiles. I think I can do it with GPO for new profiles, but I don't see a way to set it for existing profiles. I assume I have to do this with a registry setting.Hi,
The cached mode Sync Slider setting is maintained in the Outlook profile settings in the Windows registry. If you want to administer this setting via group policy, you can use the group policy templates, which are available from the Microsoft Web site. The
group policy template files are Outlk15.admx and Outlk15.adml. If you use group policy to manage this setting, the following registry data is utilized by Outlook.
Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Outlook\Cached Mode
DWORD: SyncWindowSetting
Value: integer value (Decimal) specifying the number of months (use only the following values)
0 = All (entire mailbox)
1 = One month of mailbox items
3 = three months of email items
6 = six months of email items
12 = twelve months of email items
24 = twenty-four months of email items

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.

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

If I choose "restore from iTunes backup" to move everything from old iphone to a new one, will I still be able to use the old phone for music and apps? Can the old phone be docked up to that same computer every now and then? Or will the new and old phone overwrite each other in some way? In other words, are the two phones treated as different devices when the "restore" option is used to set up the new phone? Thanks in advance.
Yes, you can use the old iPhone as an iPod touch.

I use an ipod classic 120G. When I try to launch itunes I first of all see a box stating "The registry settings used by itunes drivers for importing and burning CDs and DVDs are missing. This can happen as a result of installing other CD burning software. Please reinstall itunes" This I have done. obviously I cannot burn CDs but worse still is my ipod is not being recognised by itunes and will not sync. I have not installed any new burning softeware. Any suggestions please?

Using internal SSL Certs for Webview and Reskill (ICM 7.2.X)
Hi,
I would like to use corporate ssl certs for webview and reskill to avoid the user having to install the self signed certificate on the local machine. Has anyone any experience of this? Can it cause any unforseen problems?
My plan for webview is to create the certificate request in IIS for the default website, use this csr to generate the cert, then complete it by uploading the certificate.
For reskilling, I will assume I will have to do some command line stuff here ...
eg: keytool -genkey -keyalg RSA -keystore hostname.key
to create the key,
keytool -certreq -keyalg RSA -keystore hostname.key -file hostname.csr
to create the csr, and
keytool -import -trustcacerts -alias tomcat -file hostname.cer -keystore hostname.key
to import the new cert
Suggestions or comments for anyone who has tried this before would be appreciated.
Regards,
BrianI've never done it on a version so old, but at the end of the day it's just IIS and Tomcat and importing an SSL cert is very standard.
