Cache Mode issue

Hello,
Can some one help me with the information also the document for the Cache modes?
What is the difference between the cache mode 3 Persistent cache per Application server and 4. Persistent cache across each application server?
Also i had a question : If there is a multiple Application server exists, how will the query will get cached normally with Mode 3 and 4?
Thanks in Advance.
Regards
M.A

Simple - as it says on the tin
If you have cache per app server - then depending on the app server you have fired the query against it will either hit cache or not
If you have multiple app servers then it's really a no brainer in this manner - go for option 4

Exchange 2010 all mail clients with internal cached and internal non-cached mode users having connection status issues, login prompt -- external is fine either way

Hello,
I'm seeing an issue that started this past Monday with no recent change to our environment.
External Outlook Anywhere users and Mobile users, OWA users are unaffected.
Internal Users are affected when using Outlook of any version, 2010 or 2013.
-Internal Users normally log into their workstation with their ad credentials, domain joined machines. Outlook opens without credentials prompting ideally.
1 . Using Cached Mode:
a. Login Prompts, slowness - Since Monday, users are getting prompted to login. The prompt goes away after logging in at startup. It is also causing high CPU
on the workstations.
b. Free/Busy, Out of Office doesn't work. I can, however complete auto-setup for a new user, so autodiscover is not completely down for internal users.
c. Checking Connection Status shows connecting status on highlighted entry below without ever establishing connection (just goes away).
The outlook icon in the system tray says "Outlook is requesting data from the server":
2. Using Non-cached mode
a. No Login Prompt at startup, business as usual
b. Free/Busy, Out of Office works fine. Autodiscover is fine.
c. Checking Connection Status shows normal except, it has "casarray URL, then status is referral" it seams to flicker this constantly then go away intermittently.
d. Main issue in non-cached mode is, sometimes a user will log into windows, open outlook and it will not open and says "server is unavailable. Retry, work offline, or cancel" I can try re-opening, same message.
Only after logging out of windows, logging back in, I can get back into outlook. This is not every time, or consistent with specific users, but random.
3. Lync Pop up for credentials often, though entering the password.
URLs are correct. Autodiscover, EWS, etc.
Already tried bypassing our loadmaster load balancer with host files on clients. same issue regardless of casarray node.
Not sure what is going on.

You have a hybrid configuration with Office 365, right? You didn't provide this valuable piece of information.
In Exchange Online PowerShell run this command:
Get-OrganizationConfig | FL PublicFoldersEnabled
If the value is "Remote" then users with Exchange Online mailboxes are looking to on-premises public folders. Be sure that you have legacy pubic folder interoperability properly configured.

Exchange Cached mode sync issue.

I had an issue where one of the exchange servers did not initiate, so people had full email items on their webmail, but did not get those on their Outlook. Is there some way to ensure that if the exchange server you are connected to in a domain goes down,
you can get those emails sync without turning off cached mode and turning it back on?

It's not my experience that you need to turn off and on cached mode to recover from a server failure.

Outlook 2007 cached mode not working for old exchange 2003 users

For some reason outlook isn't receiving emails straight away when in cached mode for users which we moved (few years ago) from exchange 2003 to 2007 (we now have everyone on exchange 2010). I checked the security tab in AD and compared new and old users
and the permissions are completely different.
Creating a new AD account and linking the old email account to it, fixes the issue but that's not really an option for over 100 users.
Has anyone else had this issue?

Hello,
What's the difference between the permissions?
Can the users receive emails from OWA?
In addition, please make sure your Outlook 2007 has installed the latest update. And try to use
outlook/cleanips and check if it helps. See:

Outlook 2013 archiving doesn't work when cached mode is enabled

Hi All,
I have a problem in Outlook 2013 which I've been able to replicate on two separate PCs, operating against two separate Exchange servers. In both cases, archiving of old items does not work in Outlook 2013 when cached mode is enabled. It works
fine if cached mode is switched off so I don't believe the problem is related to the archiving settings.
Has anyone else come across this?
Thanks,

Based on my knowledge, Outlook auto archieve setting is stored in registry and only affects on local host.
If the AutoArchive doesn't work anymore, please refer to the follow article to troubleshoot the issue

If we are talking about Microsoft Exchange Online Archiving, I think it would run fine when you in Exchange online mode as your expected.

Send As not working with cached mode enabled

Hi
I am having some issues using Send As. We are running Exchange 2010 Version 14.2 (Build 247.5) and Outlook 2013.
I have done the following:
1. created a mailbox user
2. created a security group and added my own account
3. added the security group with Send As permission through ADUC on the mailbox user
4. Waited a day and tried to send as the mailbox user, but it fails
If I disable cached mode or use OWA it works perfectly. The mailbox is NOT hidden in the address list.
I have seen this behavior before, but can't remember the "fix"?
Lasse

Hi,
From your description, the send as permission works well via OWA or Exchange online mode, the send as permission is configured successfully. The issue is related to Outlook side, in your case, I recommend you create a new profile and check the result.
Hope this can be helpful to you.

"Sent Items" folder can not be synced up in time for Outlook 2013 cache mode

Hi,
I found a strange problem in Outlook 2013 cache mode. Hope anyone can help me find out if it is the new design of outlook 2013 or outlook 2013 issue.
I am using Exchange 2013 and Outlook 2013 client. I created two outlook profiles in two machines separately with a same exchange user, the difference for the two profiles is one is in cache mode, and the other is in uncache mode.
I launched outlook using the profiles in the two machines, go to "Sent Items" folder, I assume there are some messages in this folder in your mailbox, do below steps:
1. modify one of the messages in the "Sent Items" folder from the profile in cache mode, in this case, the changes to the message will be synced up to the profile which is in uncache mode immediately.
2. modify another messages in the "Sent Items" folder from the profile in uncache mode, in this case, the changes will never be synced up to the profile in cache mode.
In the second action above, even if I clicked "Send/Receive" button, and waited for whole night, the changes was not synched up to the cached mode side. The way I can get the latest changes to the "Sent Items" folder is "clear
offline items" and click "Update folder" or I need to remove and create the profile again.
All in all, the changes to the items in "Sent Items" folder of Outlook 2013 which was did from cache mode will be synched up to exchange server side immediately, but the changes which was did from exchange server side will
never be synched up to the cache mode side unless the end-user clear the offline items and update folder or create a new profile again.
Any help would be appreciated, thanks in advance!
Best Regards, Emily

The first behavior is by design even in the previous version of Office.
"1. modify one of the messages in the "Sent Items" folder from the profile in cache mode, in this case, the changes to the message will be synced up to the profile which is in uncache mode immediately."
Uploading local changes ---- By default, when you make a change locally, that change is synced to the server after 15 seconds. When you make another change within those 15 seconds, then the timer is reset again. As now you
could in theory hold off synchronization indefinitely, there is the maximum timer. This timer is started after the first change that you made and when it reaches 60 seconds, then a synchronization will occur to upload all the changes that you have made thus
far, no matter how many seconds are left on the upload timer.
However, in second section, this should be a downloading server changes
behavior ---- When a server side mailbox change occurs, Outlook is notified by the Exchange server of this change. By default, Outlook will then wait 30 seconds before synchronizing these changes. If there are any other changes occurring
at the server level within these 30 seconds, then these changes are downloaded at the same time as well.
At this time, please directly modify the message in sender items folders through Web-based access and then wait over 30 seconds to check if the items changes from cache mode profile. Please also test if we can reproduce that in other folder.
Let me know the result. Thanks.

Shared Mailbox folders missing in Outlook Cached Mode

Since I got no responses to my
original post in section, "Exchange Server 2013 - Sharing and Collaboration: Site Mailboxes and Public Folders" I'll give it a try here...
We have Exchange 2013 Server (Version 15.0 - Build 913.22). I have a shared mailbox for our support team, "Support Center". This mailbox is configured as a "SharedMailbox". Our team members have been given Full Access
either by the Admin Web Interface or by "Add-MailboxPermission -User user1 -AccessRights FullAccess".
I am seeing this issue using Outlook 2013 Pro plus that manually created subfolders either in the root of the mailbox or folders under the Inbox are not visible. These folders are just for organization, like "Work Order Entered" and are not
like contact folders or any other special folders.
We determined if the Outlook client is configured for "Online Mode"/non-cached the folders appear and are accessible, but if your enabled Cached exchange mode the folders disappear and are no longer accessible. I have cahnged the cache slider
to go all the way right to say cache everything, not just the last so many days, but this did not resolve the issue either.
Upon further testing I have the same issue when I use Search-Mailbox with Targetmailbox and TargetFolder to my "Discovery Search Mailbox". The folders is created and logs are made, but the folder does not show unless I am in exchange online
mode and not cached.
HELP PLEASE! This is very annoying and we need cached mode for the registry key to place sent mail in "SenderAndFrom" sent items. It doesn't work in online mode.

Hi CHase,
shared mailboxes shouldnt be cached,only user mailboxes should.Reason for this is because it will download all info from shared mailbox and it can take some time.All company info will also be stored locally,so its security concern.
You mention that you turn on cached mode,is this under user mailbox or additional mailbox as shown below?
The one to left should be fine to cache all,but the one to the right only first check mark should be on.We have this configuratuon and senderandfrom registry works well.
If you access OWA,then choose to open another mailbox,then choose the "support center" mailbox,do you see all folders?
By granting full access doesnt give you send as permission,for this you will need to run this command:
Get-Mailbox "[email protected]" | Add-ADPermission -User "[email protected]" -ExtendedRights "Send As"

Calendar tracking not consistant when meetings booked by delegate in cached mode

Situation:
Exchange 2010 Sp3
Outlook 2010 SP1 Cached mode, with delegate having full access to manager's mailbox with auto mapping on.
Whe the delaget books a meeting in the managers callander. Some of the response are not relected in the tracking on the meeting. The patern is that everybody who responded quickly are not reflected, but at some point the responses start being
reflected in the tracking.
I think that the issue is that when some of the responses start coming in, the meeting has not yet been synced to the owners mailbox. When the reponse comes in, there is no meeting object to update, so it gets ignored. When the calendar oject
finally gets synced the response that come in from that point , are processed and get reflected in the tracking. this is particularly obvious for meeting rooms, since our rooms are setup to auto-accept and they response within seconds.
I have tried changing the Cache setting, to not cache shared data, this way when the delegate works in the Manager's calender the change are happening directly in the Mailbox. With this configuration all the meeting response are getting processed.
I can use this workaround for some people but we do have some admins that want to cache the manager's mailbox/Calendar for viewing offline so I also need to find a solution for them.
Thanks
Marc

It is the default behavior, but it also causes many undesired issues. For instance, consider the following:
If I have a small mailbox, but I have several large shared mailboxes, when I create a profile, those shared mailboxes are added to my OST. In your estimation, this is all well-and-good. However, I work for a bank - we have many slow WAN connections
(one for each branch), and a large number of users across these connections. If you download one large shared mailbox to your workstation, you will swamp the network connection for a very long period (we've had WAN outages caused by shared mailboxes
that lasted most of a day). Add to this the fact that our tellers do not use the same computer daily, each time they go to a different computer, the cache needs to be totally refreshed.
I have C*Os in this company who have many admins responsible for their Calendar and Inbox. These admins aren't always able to communicate before scheduling meetings. Let's consider your situation - the C*O calendar is updated in real time when
changes are made. Those up-dates are still not replicated real time to the delegates, so even in your best case, they will still not be up to date when they schedule meetings. (And considering the current operation, they are as much as 15 minutes
behind if they all cache the C*O mailbox.)
We have many shared mailboxes in our organization. Some of these have many users who have full access. We have found several issues if these people cache the shared mailbox, such as:
Many times, these users will open an item to work on it, which marks the message as read so others will by-pass it. We had one group who had six responses to a message because six separate users opened the message and responded. After all, the
message showed as unread in their cache.
Folders created in the shared mailbox aren't visible to the other users, and may never appear (we've tried forcing folder updates as well as forced replication and nothing causes these new folders to appear).
Users commonly move items to sub-folders within the mailbox. With cache enabled, we've had ticket opened because one person moved a message to their folder, but someone else moved it to their folder. Since all were working from cache, the last
cache to update won this contest.
And finally, we have found that while Outlook does a good job of ensuring the cache of the primary mailbox is up-to-date, it doesn't update the shared mailboxes as readily if the workstation is busy, which for our exec admins is most of the time.
So the cache for the admins of our senior execs (which as I said above are multiple) was rarely updated on a timely basis. And all of these admins are working on high-speed connections to the server, so it's not a WAN issue in these instances.
Turning off "Download shared folders" fixed all of these issues at the minor expense of taking longer to open items in the secondary mailboxes.

Cannot save free/busy information - Cached mode

So I have a calendar Admin, that has the ability to send meetings on behalf of new hires. She was is cached mode and sent out a few invites. Everyone she sent the invites to received the meetings, accepted the meetings and have the meetings on
their calendar. My Calendar Admin see's the meetings on the new hire's calendar, but no one else can see these meetings on the new hires calendar. My Calendar Admin mentioned seeing the infamous pop-up "cannot save free/busy information":
I disabled cache mode on my Calendar Admin's Outlook 2013, once I disabled cached mode and close/re-opened Outlook, all the the invites she had sent for the users were gone, no longer listed on the "Organizers" calendar... so somehow the invites
were only saved locally to her cached calendar. This smells like a pretty bad bug for users with access to shared calendars and seems like they MUST be in NON-CACHED mode when sending any invites on behalf of someone else. So now, all the meetings
are on all the calendars of the "invitees" but not on the new hire (organizers) calendar. This is seems to be a reproduceable bug that I'm hoping isn't working "as designed"
Are there any known bugs with this process? Is there a way around this other than disabling cached mode? Where do these meetings actually save when in Cached mode on a shared calendar?
Thanks in advanced

Hi,
Please check this following setting on her account first.
In Outlook, click File, click Account Settings, and then click Account Settings (again).
Select the Microsoft Exchange account, and then click Change.
Click More Settings.
Click the Advanced tab.
Select the Download Shared Folders option.
Click OK, click Next, click Finish, and then click Close in the Account Settings window.
If this doesn’t work, please try to repair or re-create outlook profile to check this issue.
Exit Outlook.
In Control Panel, double-click Mail.
Click Show Profiles.
Select a profile.
Click Remove.
Click Add to create a new Profile.

Exclaimer manager signature does not update sent items for outlook 2013 clients when using cached mode

Hi
I have Signature Manager Exchange Edition 2.0.3.0 installed on the hub servers.
I have enabled Sent Items update.
some clients are not getting signature update in the sent items of outlook while using cached mode.
from OWA, and MS Outlook when connected online, the signature is updated in the sent items.
I have two CAS servers and two mailbox servers. all with Exchange 2013 SP1
I tested each CAS server for the URLs of Autodiscover and EWS, with no errors or warnings.
I also test Autodiscover through
https://testconnectivity.microsoft.com . I go successful result.
Outlook clients are updated to the latest version 15.0.4701.1000
for outlook clients; I deleted outlook profile, deleted outlook folder in the user profile, re-created the outlook profile, with no luck.
from Exclaimer event logs on the Hub servers. the sent items update is successfully updating clients. below is the screenshot of an event for one email message which is successfully updated from exclaimer but it did not update on the client outlook while
using cached mode.
Since the issue is with multiple users, I am searching for a centralized solution
Mashhour Faraj

Dear Mashhour
Here you go
Employees can see their email signatures and disclaimers
With Exchange 2013, a Microsoft Outlook user can’t see any added email signatures or disclaimers as they are added to an email when it passes through the Exchange server.
Signature Manager Exchange Edition lets email users see their email signature and corporate disclaimer within the Sent Items of their inbox, giving them visual confirmation of the processed email
Source -
http://blog.exclaimer.com/exclaimer-signature-manager-vs-microsoft-exchange-2013/
Updating to the latest version of signature manager exchange edition will help you to resolve this problem for sure
Or you need to contact them to find a solution on this .
I'm pretty much sure that this problem is related with some version mismatch on their s/w on exchange 2013 which is causing this issue.

Outlook 2010 stops receving new emails when in cached mode

User has an Outlook 2010 issue that has been called in on NUMEROUS internal helpdesk tickets and has never been resolved. What happens is several times a week his Outlook 2010 client on his Windows 7 SP1 laptop will stop synchronizing
new messages from Exchange 2010 (not sure exact build/version). His admin assistant still gets his new messages in her Outlook 2007 SP3 client (as his delegate) and he still gets new messages on his iPhone via Good GMM. If he logs in to Outlook
Web Access all his messages are there.
We already tried toggling Cached Exchange mode off and back on several times, the problem still returns whenever in cached mode.
We already tried deleting the outlook.ost file and letting it rebuild several times, the problem still returns.
We already tried deleting the entire Outlook profile and letting it rebuild several times, the problem still returns.
We already tried deleting the entire Windows user profile and letting it rebuild several times, the problem still returns.
We even gave him a whole new laptop, the problem still returned.
Problem started with Outlook 2007, upgraded to 2010, problem returned.
Seems to happen more often when the laptop resumes from sleep, but not always.
Most add-ins are disabled except for McAfee and a few other essential Microsoft ones.
He does not have ANY rules or alerts set, none at all.
He does not have any other mailboxes or shared calendars in Outlook and RSS feeds are off.
He does have 8 PST files and several of them are quite large (three are 2GB each, one is 4 GB).

Hi Smitty,
If change other user account on his laptop, and use outlook cache mode, is there the same issue?
If not, I recommend you try to move this mailbox to another database, and check the result.

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,
Rob

Hi,
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.

Exchange 2013 - Attachments in *.EML files missing in non-cached mode

Hello
Our client recently upgraded from Exchange 2010 to Exchange 2013. Since the migration they have had issues with an archiving system they use. Bascially the archiving system creates .eml files of journaled emails.
The issue our client has is when Outlook is running in non-cached exchange mode any attachments within these .eml files are missing when the eml file is opened. If they change to cached mode the attachments show up fine.
It's almost identical to the following issue I found while browsing the net:
http://social.technet.microsoft.com/Forums/office/en-US/b9a390a9-e014-4098-ad6e-dd377a53422a/office-2010-exchange-2010-attachments-in-emlemails-are-invisible?forum=outlook
Aside from the Exchange version this is exactly what is happening for our client. Is anyone aware of whether the same issue fixed in Rollup update 5 for Exch 2010 SP1 is still present in Exchange 2013?
Our client has already said they don't want everyone using cached exchange so I can't tell them that. Is there a way to manually fix the issue or are we going to have to move back to Exchange 2010 while a patch is sent out? Does anyone know exactly what
the issue is?
Many thanks in advance.

Hi,
I know there was this issue with Exchange 2010, but haven't noticed the same issue in Exchange 2013. The suggestion would be to keep Exchange fully updated - It seems you have done so.
I'm not sure when SP1 will be released, you may post this question to Exchange forum since it may be more related:

Outlook 2010 -Mailbox Cleanup wizard does not start when using cached mode

We are using Outlook 2010 with Exchange 2003 server.
Currently all users are using online mode, but for some problem, I need to persuade the users to change to use cached mode.
Recently we find that when user
mailbox reaches its size limit and try to send an email message in Outlook 2010 that is in cached mode, the email message stays in the
Outbox and the Mailbox Cleanup wizard does not start. It just prompts
for "send and receive error". As most of the user would not look for what the error is referring and just call IT to fix. Even worst is, they didn't realize that the mail is still in outbox.
I find the KB2544027 describing this issue but was not available and suggest to install 2596485.
http://support.microsoft.com/kb/2544027/en-us
I've try to install the hotfix and install Office 2010 SP2 but just doesn't work.
Does anyone know how can I fix it?
Thanks!

Hi,
Based on my research from the internal resource, this issue has been fixed in build 14.0.6126.5000 or less. I suppose that the hotfix not available because it has been involved in the release.
I’d like to confirm your Office 2010 build number so that we can conduct a deeper analysis on this issue.
In addition, make sure you have installed the latest update for Office 2010.
