Online Archive Db Size

I have created an Online Archive and retention policy based around moving email that is a year old to the archive Db.
The one user I have enabled with this policy, had a mailbox which is 6Gb in total. I ran the Start-ManagedFolderAssistant CMDlet against this one user, and saw that his email was visibly moving to the archive.
My question is that although the user has a 6Gb mailbox, of which I can see that 3.43Gb is now assigned in the Archive db, the actual size of the archive EDB file is now 18.5GB!
What is the reason for the massive disparity in the amount of data residing in the archive, and the actual size of the database?
I ran the Start-ManagedFolderAssistant command several times during the day, as the process of moving mail appeared to have stopped, this caused the process to start again however by doing that is the users data being duplicated each time I run the command?

Hi,
Across the lifetime of an Exchange database, its size will grow as the number of items it contains grows, the database file (.edb) will increase in size as necessary. However if the number of items in the database decreases the edb file won’t shrink,
rather the freed space within the database is held as whitespace.
To recover the whitespace, one way is to do offline defrag, and another way is to move to the new mailbox database.
And I would like to explain that the EDB size = Size of Mailboxes + Size of Retention Mail Items + Size of Retention Mailboxes + White Space.
So we have to consider about the dumpster messages and disconnected mailboxes when it comes to the size of edb file. Therefore, it is possible that the edb file size is larger than the total size of the mailbox.
Hope this help.
Best regards,
Belinda

Winmail.dat attachments after importing PST into online archive

Hi, we enabled the online archive feature on one of our Office365 exchange account. Later, we used the PST capture tool to import a PST file into the archive. Now after importing, the user came back saying he sees winmail.dat files as attachments. Prior
to uploading the PST to the online archive the attachments were visible normally. The PST file belongs to the same user. Its an old PST file attached to his mailbox since a long time. We then subscribed to the online archive plan for his account and used the
PST capture tool for importing the emails. To isolate the cause of the issue we tried dragging an email with an attachment from themailbox to the online archive from within Outlook. The moved email appeared correctly with attachment in his archive. We have
not tried importing the whole PST from within outlook, as the size of the PST is too large (32 GB). Could someone please help resolve the issue.
Thanks in advance.

Exchange Online Archive and Single Item recovery

We are currently looking to implement online archiving in Exchange 2010.
From my perspective, we are doing it to relocate the older messages to some cheaper storage, while making primary mailbox sizes are little more manageable.
Management however, want to ensure that once an item is moved to the online archive that it cannot be permanently deleted until after a 7 year retention period (for discovery purposes).
Journaling isn't an option at this point..
We have an Archive RPT which moves the items to the users archive after 90 days.
We have another RPT which will Delete items from the Archive after 7 years (Delete no Recovery).
We then have "Keep deleted Items for", set to 30 Days on the Primary Mailbox Database.
and then have "Keep deleted Items for", set to 7 years (2555 Days) on the Archive Database(this is so that items are not immediately deleted if the user manually deletes from the archive).
Obviously with this setup, users will be able to purge items from the "Deletions" sub folder (Recover Deleted Items) if they want to remove it from the archive.
My understanding is that if I enable Single Item Recovery for everyone, then the items that the user might remove from the "Deletions" sub folder will be transparently moved to the "Purges" sub folder, and are therefore discoverable
if required, up until the retention period of each database (30 days for Primary mailbox, 7 years for archive).
This sounds like exactly what we are after.
Thus my questions;
Apart from the obvious storage implications of doing this (7 years is alot of email), are there any other issues\risks associated with going down this method for email retention?
Is there a better way of achieving what we are after? I dont suppose we could completely restrict deletion access to the users archive completely for example?
If a user was to drag an item back into their primary mailbox.. and then delete it before the Managed Folder Assistant moved it back to the archive.. Would that be a potential hole in the retention requirement?
Thanking you all in advance for your insight..

You may want to use Litigation Hold to have users unable to delete the item permanently.

I know it works on Active mailbox but not sure if the same attributes available for Archive Database. Just run the cmdlet and see if it can be done.

Search results for Online Archive Limited to 250 results

We are running Office 365 Pro Plus with Exchange 2013 CU4 on premise (nothing in the cloud). When searching the Online Archive (with instant search or Advanced Find) within Outlook the results are limited to 250 items. This is frustrating to
people because we have email going back to 2006 so they are expecting many more results. I understand the need to balance performance, but why is there not a way to override this limit? I have searched but have been unable find a way - please
let me know if one exists.
Thank you, Jeff

Hi,

Online Archive Warning Alerts not being sent to Users

We have exchange 2010 SP3 Rollup 7 and we utilized Online Archive of Mailbox. Each user has 2 GB of Archive Quota and 1.5 GB of Archive Warning Quota. Users don't receive any warning alert if they exceeds Archive Warning Quota. I suspect this is default
behavior in Exchange 2010.
Is there any change in this behavior in Exchange 2013 ?

Does user receive warning message via OWA?
Ans. - No
How do you set the Archive Quota and Warning Quota?
Ans. - It's
the same way you have mentioned, We have archivequota of 2 GB and ArchiveWarningQuota of 1.8 GB.
Generally, Warning Quota Alert works well, I find a blog on mailbox quota trouleshooting for your reference, hope it is helpful.
Ans. - Have you seen any archive warning quota email, I don't find any sample email
or reference for the same. Could you try to reproduce if you have any testing environment.

Online Archive only visible in Outlook 2010 after OWA logon

Dear.
We implemented Exchange 2010 native archiving. We created our own retention policies, applied them to the mailboxes and archiving started successfully exactly as we want it.
We’re using Outlook 2010 clients with both: cached and non-cached mode. The strange thing is that for the online archive to be visible in outlook, the user needs to logon to OWA
first and only once. Afterwards, online archive stills visible in Outlook 2010.
Is there any other way to make the online archive visible without forcing the user to do a one-time logon to OWA?
Thanks for the feedback.

Online Archives for Outlook 2013 do not appear in Outlook 2013 running on Terminal Server

Hello,
We are currently attempting to get our users away from using PST files and instead use the Personal Online Archive feature but have come across a problem
Environment
Windows 2008 R2 Remote Desktop Services (Terminal Server)
Office 2013
Citrix 6.5 XenApp
So on the Exchange side I went through the steps of setting up my PST use as a guinea pig for testing. I was able to setup the Archive database, enable archiving on my mailbox, and import my PST into the Archive database.
I then opened Outlook 2013 on my stand-alone PC and there was my Online Archive. Great!
I then double checked and also saw it on the OWA site on the Exchange server. Super!
I finally logged into our RDS (Terminal) server and opened Outlook 2013 there. But the Online archive was not there. Hmmm..
I did some researching and this article about Outlook 2010 suggested it was a permission issue:
http://social.technet.microsoft.com/Forums/office/en-US/1e8d5d4b-e26b-4be6-b646-eb6e796c6295/exchange-2010-mail-archive-missing-in-outlook-2010-shows-in-owa?forum=outlook
So I ran through those steps in Powershell but no change.
I also don't think it's a licensing issue because the license I have on my stand-alone PC is the same volume license keys (MAK) as on my Terminal Server.
Soo... I'm a bit stuck and was hoping for some help. I can't proceed with migrating other PST files to the online archive until I get this resolved.
Thanks

Hi,
In theory,
Outlook reads the
msExchDelegateLink attribute of the user in AD to display the additional mailbox (Online Archive folder).
Since the standalone client can display the archive mailbox properly, it seems this attribute is available in AD. I suspect the issue locates on the way that the terminal
clients access the server. I suggest we check whether the client has properly permission to connect to AD when accessing remotely.
Thanks,

Outlook 2013 - Online Archive folders do not remember expand / collapse

For our QA group, we have just upgraded them from Office 2010 to Office 2013 SP1. We have one user that noticed something. With Outlook 2010, the client would remember which folders he had expanded or collapsed under his "Archive" (the online archive
generated by the Archiving feature of Exchange server). However, once we upgraded him to Outlook 2013, this is no longer true. Now, the "Online Archive" header is fully collapsed when he open Outlook every time.
To test, I created a small folder structure with some items in my own "Online Archive" section and was able to reproduce this behavior. Outlook 2013 will remember which folders are expanded or collapsed for the folders in my Inbox but not for the
folders in my Archive. Is there a way to have Outlook 2013 remember the expand / collapse settings for the Archive?

Urgent: Huge diff in total redo log size and archive log size

Dear DBAs
I have a concern regarding size of redo log and archive log generated.
Is the equation below is correct?
total size of redo generated by all sessions = total size of archive log files generated
I am experiencing a situation where when I look at the total size of redo generated by all the sessions and the size of archive logs generated, there is huge difference.
My total all session redo log size is 780MB where my archive log directory size has consumed 23GB.
Before i start measuring i cleared up archive directory and started to monitor from a specific time.
Environment: Oracle 9i Release 2
How I tracked the sizing information is below
logon as SYS user and run the following statements
DROP TABLE REDOSTAT CASCADE CONSTRAINTS;
CREATE TABLE REDOSTAT
AUDSID NUMBER,
SID NUMBER,
SERIAL# NUMBER,
SESSION_ID CHAR(27 BYTE),
STATUS VARCHAR2(8 BYTE),
DB_USERNAME VARCHAR2(30 BYTE),
SCHEMANAME VARCHAR2(30 BYTE),
OSUSER VARCHAR2(30 BYTE),
PROCESS VARCHAR2(12 BYTE),
MACHINE VARCHAR2(64 BYTE),
TERMINAL VARCHAR2(16 BYTE),
PROGRAM VARCHAR2(64 BYTE),
DBCONN_TYPE VARCHAR2(10 BYTE),
LOGON_TIME DATE,
LOGOUT_TIME DATE,
REDO_SIZE NUMBER
TABLESPACE SYSTEM
NOLOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
GRANT SELECT ON REDOSTAT TO PUBLIC;
CREATE OR REPLACE TRIGGER TR_SESS_LOGOFF
BEFORE LOGOFF
ON DATABASE
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
INSERT INTO SYS.REDOSTAT
(AUDSID, SID, SERIAL#, SESSION_ID, STATUS, DB_USERNAME, SCHEMANAME, OSUSER, PROCESS, MACHINE, TERMINAL, PROGRAM, DBCONN_TYPE, LOGON_TIME, LOGOUT_TIME, REDO_SIZE)
SELECT A.AUDSID, A.SID, A.SERIAL#, SYS_CONTEXT ('USERENV', 'SESSIONID'), A.STATUS, USERNAME DB_USERNAME, SCHEMANAME, OSUSER, PROCESS, MACHINE, TERMINAL, PROGRAM, TYPE DBCONN_TYPE,
LOGON_TIME, SYSDATE LOGOUT_TIME, B.VALUE REDO_SIZE
FROM V$SESSION A, V$MYSTAT B, V$STATNAME C
WHERE
A.SID = B.SID
AND
B.STATISTIC# = C.STATISTIC#
AND
C.NAME = 'redo size'
AND
A.AUDSID = sys_context ('USERENV', 'SESSIONID');
COMMIT;
END TR_SESS_LOGOFF;
Now, total sum of REDO_SIZE (B.VALUE) this is far less than archive log size. This at time when no other user is logged in except myself.
Is there anything wrong with query for collecting redo information or there are some hidden process which doesnt provide redo information on session basis.
I have seen the similar implementation as above at many sites.
Kindly provide a mechanism where I can trace which user is generated how much redo (or archive log) on a session basis. I want to track which all user/process are causing high redo to generate.
If I didnt find a solution I would raise a SR with Oracle.
Thanks
[V]

You can query v$sess_io, column block_changes to find out which session generating how much redo.
The following query gives you the session redo statistics:
select a.sid,b.name,sum(a.value) from v$sesstat a,v$statname b
where a.statistic# = b.statistic#
and b.name like '%redo%'
and a.value > 0
group by a.sid,b.name
If you want, you can only look for redo size for all the current sessions.

Online Archiving and Mailbox sharing exchange 2010

Hi Guys
is it possible to share a mailbox without sharing the online archive attached to it, the issue I'm having is that one of my users is sharing his mailbox with his PA, he happens to have a very large amount of subfolders under all his folders and not just
the inbox, this also includes his sent items and deleted items that have subfolders in them too, his PA happens to need access to these folders too. but with the online archive attached, the amount of subfolders connected appear to be more than outlook can
handle, and it throws an out of memory error and the user then has to restart outlook before being able to send any mails again. alternatively is there a way to share all the subfolders without painstakingly setting the permissions on each folder one by one.
Cheers

You can open the database where user mailbox is located in ExFolders and then add permission for Inbox folder and then propagate that permission to all subfolders.
This article is using PFDavAdmin but will help you to understand what you need to do via ExFolders on Exchange 2010...

Online Archive Search Does Not Search Folders

Outlook 2010 (14.0.7113.5000) SP2 MSO (14.0.7140.5002). We have multiple user that can search the archive and get results, but if the mail item is in a folder in the online archive it will not find it. Seems to be the same situation on OWA. Any guidance
or help would be appreciated.

Hi,
What’s you Exchange server version? Please confirm if the issue happens to all users when searching the Online Archive folder in both OWA and Outlook client.
If that is the case, the issue may be related to the Search feature in Exchange server. Please restart
the Microsoft Exchange Search Service or rebuild the Full-Text Index Catalog to have a try:
http://technet.microsoft.com/en-us/library/aa995966(v=exchg.80).aspx
If it doesn’t work, please collect more event log and ask a question in Exchange forum for further troubleshooting.

Outlook Online Archive Requesting for Authentication

I am currently performing a migration from Exchange 2010 to Exchange 2013. For the new Exchange 2013 environment I have 3 servers. Two servers are in the main site and one in the disaster site. The first server in the main site and the one in the
disaster site have both the mailbox and client access role and a set up in a DAG. The second server at the main site is to be used to host archive mailboxes for users and has only the mailbox role installed. The 2010 setup is also similar just that all the
servers are located at the main site. I migrated a couple of users from the 2010 server to the new 2013 server. I realize that when a user on the Exchange 2013 server uses Outlook(both 2010 and 2013) and tries to expand his online archive it requests for authentication
and after entering the credentials is still unable to access it. However, the same user can access the online archive when they use OWA.

Hi Mavis,
It keeps prompting the password again and again.
The Test E-mail AutoConfiguration looks normal. Proxy authentication is also set to NTLM like in the screenshot above. The only observation is when I try to expand the Online Archive and i look at the Connection Status I see the guid of the user's archive mailbox
with a Status of Connecting like shown below:
When I cancel the authentication prompt i get the error below:

Online Archive folder can't be opened after migration into Exchang2013

Online Archive folder can't be opened after migration from Exchaneg 2010 to Exchange 2013.
Windows8.1 MS office 2013, Exchange 2013, Online mode
error: Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance.
Is there any solution about this issue?

Select it and open the Info dialog. In the Sharing & Permissions section, you should have read & write access, and everyone (else) should have read access. If that's not the case, click the lock icon, authenticate, and make the necessary changes. Close the window and try again.

Read only online archive

Hello
Is it possible to make an online archive read only with Exchange 2010?
Maybe making the message store read only ?
The idea is to make some PST online... but read only.
Regards,
Stephane

then add the data to an existing mailbox, in a specific folder and restrict the access/visibility to that folder only.
However, that mailbox owner will have full access...

Exchange 2010's "Online Archive" doesn't appear in Outlook 2010

Hi,
I recently installed Exchange 2010, and all is working fine but the online archive feature.
I activated it for 2 of my users, it appears correctly in OWA, but doesn't appear in Outlook 2010 (Tech Preview).
What I am missing ? The only howtos I found state that you only have to setup Outlook, and the main mailbox + the online archive will appear... But I just have the main mailbox.
If you've an idea... :)

I did some testing on this whole Personal Archive thing as even when using a new version and new license key the archive wasn’t showing in Outlook 2010 (yet was showing in OWA).
So I setup two machines (VMs) running Windows 7 Ultimate.
One was x64 and the other x86 but vanilla installs.
Installed Office 2010 Professional Plus download from TechNet (the iso image with both x86 and x64 versions on it).
Installed the lastest Office updates published via MS Update.
Used the same license key for both installs of Office.
Exchange 2010 backend running SP1.
When the machines are not in a domain the archive doesn’t show in Outlook (both x86 and x64).
Pop the machines into the same AD domain as the Exchange server and hey presto the archive shows on both Outlook versions (x86 and x64).
Just to check things I removed them from the domain - archive folder missing again.
Re-added back to domain - archive folder shows.
It seems for the TechNet version anyhow the machine should be in a domain.
I can’t comment on other versions/license keys.
Regards
