Outlook 2013, intermittent "exchange server not avaliable"

I have a virtualised environment.
----The setup:-----
two vHosts, vmware 5.5, 4 CPU, 196 GB RAM, Storewize v3700, 20 10K disks in RAID10
two win 2012 exchange 2013 servers
two win2012 DCs
five (5) Win2008R2 RDS hosts + 1 2008R2 Connection broker
60 users on the RDS server in outlook online-mode. no cache
Office 2013 on the servers
-----the problem:---
Some random users have random problems opening outlook.
A user tries to open outlook and gets the message "exchange server not avaliable".. he says OK, and outlook closes. - opens outlook again, and everything works..
This happens at random times for random users
CPU, disk and network activity are very low on both vhosts and there is a lot of avaliable RAM on all guests
I don't know if its related, but the larger the mailbox is, the longer it takes to open outlook.. some times up to 6-10 seconds.. At idle times, outlook opens in less than a second..
Any ideas?

Hi,
According to your description, the issue randomly happens on random users and all users use online mode. Thus, I recommend you use performance monitor to double check if the issue is caused by performance and we can also check if there is any 9646 error
code in the event log.
http://technet.microsoft.com/en-us/library/dd335215(v=exchg.141).aspx
We can use performance monitor to check the change of the counters: RPC request, RPC average latency and RPC operation/sec
Referring to others’ suggestions, the issue may be caused by E1000 vNICs. Maybe we can temporarily try to update to E1000e. Alternatively, you can ask for help from the VMAS support.
If you have any question, please feel free to let me know.
Thanks,

Thanks for your reply Angela.
The vNICs are already E1000e. The next step for me is to try upgrading them to VMXNET3. There are no errors in the event log related to this. I have not yet gone the perfmon-way, because I figured that when disk activity and CPU / RAM consumption is
so low, it wouldn't be an issue.
I was connected to the system yesterday evening where I experienced this error. There were a total of 8 users connected to the system, having only the ERP system running. I was the only user on that particular RDS host, and vmware performance metrics say
the servers are under very low load-level..

Problems using Outlook 2013 with Exchange Server Small Business Server 2003

Hello,
We have just upgraded our Office suite from Office 2007 Pro to Office 2013 Pro. When I try to configure Outlook 2013 to connect to Exchange Server 6.5 (SMS 2003) I get an error "Outlook 2013 being blocked by current version of Exchange Server".
Outlook 2013 at present is not communicating with Exchange server 6.5
Are there any fixes I have to install on our SMS 2003 server to allow Outlook 2013 to work with SMS 2003 Exchange Server?
Any configuration changes I need to make? Any help is appreciated.
Thx

Outlook 2013 with Exchange Server - Changed custom form for contacts is not shown

Hello,
Our infrastructure:
Exchange Server 2010
Outlook 2010
Outlook 2013
Windows 7 Pro, Windows 8 Pro and Windows 8.1 Pro
The situation:
We've used an old custom form for contacts, worked perfectly fine
I've updated the form (adding some new custom fields and checkboxes) using Outlook 2013 and publishing the form (with a new name) to the Exchange folder
I've set the form as default form in our contacts folder
I've used this Script to set the new form for the existing contacts and the name of the new form is saved correctly
BUT if I open a contact in our Exchange contacts folder, Outlook 2013 (Outlook 2010) still shows the old form
Steps I've taken so far:
Cleared Outlook forms cache
Repeated the above steps 1-4 in Outlook 2010
Switched Cached Exchange Mode off and back on
Allowed Scripts in Trust Center Settings
Used a new clean Windows installation with a new Outlook 2013 installation
Used different Exchange users on different systems, but some behavior when opening contacts
I'm out of options I can think of, so maybe somebody else has some new view on this problem.
Thank you very much in advance!
Greetings,
Karl

Hi,
Is the Exchange folder in which the custom form is published available to all users?
From the description, the script used to work for the old custom form, correct? Which version of Outlook did you use with the old custom contact form? Outlook 2010/Outlook 2013 or an earlier version? If you used the script with an earlier version of Outlook,
we can't make sure it will still work with Outlook 2010/Outlook 2013.
In addition we may also try creating a new contact form and test the steps to see if it will work.
Please let me know the result.

Problem connecting outlook 2013 to exchange server

Hello,
I recently bought a new windows laptop for emailing (our company is otherwise only using Mac).
Setting up Outlook with the intended email address failed, and at this point, when clicking Outlook, I get the following message:
"The connection to Microsoft Exchange is unavailable. Outlook must be be online or connected to complete this action."
The only option is to click "ok".
The following window is then opened:
"Microsoft Exchange"
It has only one tab, containing:
"Microsoft Exchange server" window, in which I've entered the server address.
"Mailbox" window, in which I've entered the email address. There is a button called "Check Name".
If clicked, the following message shows up:
"The name can not be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
By clicking "ok" anyway, the following message appears:
"Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The file C:\xxxxxxxxxxx.ost is not an Outlook datafile (.ost)."
The problem seems to be that there is nothing I can do to change these messages. I have access to the correct server name, address etc.
What to do?
Thank you for your help!

Hi Scout,
Thank you for your question.
As Ronomatic said, we could clear the present profile and re-build profile by the following link:

Ping or Nslookup；
Waiting your reply.

Outlook 2013 and Exchange 2007 not always syncing read status of a message

Out users are experiencing this issue from time to time. Outlook 2013 is using Exchange mailbox as default storage (Exchange 2007 SP3). Sometimes it shows that Inbox has one or few unread messages (Inbox name is bolded and there is a number near it). But
a user can't find any unread messages in the inbox. If he logs to his mailbox via OWA, then he can find those unread messages. But they are marked as read in the Outlook. So it seems Outlook 2013 has issues syncing with Exchange 2007 as we have never experienced
such issues when using Outlook 2007 with the same server.
Any hints on how to make this thing go away, other than instructing users to log via OWA and mark unread messages as read?

Hi,
Switch to Exchange Online Mode, does the issue persist?
It seems to be a sync issue between Outlook and Exchange, make sure the Internet connection is good. Let me know if the issue persist after clicking
Send/Receive All Folders button.
Try to run Scanpst.exe to repair the local data file in case the data file has been corrupted:

Strange Exchange name when connecting with Outlook 2013 to Exchange server 2013 SP1

I've setup a test environment with Windows Server standard 2012 R2 and Exchange Server 2013 SP1...
In- and outbound SMTP works fine, as well as connecting with OWA and Mac Outlook client...
Oddly though when setting up an Outlook 2013 connection....it recognizes the email address correctly, but later on can't connect and shows a dialog to enter the server and email account manually....though the profiled fields show something like:
Exchange Server: [email protected]
Mailbox: =SMTP:[email protected]
When I fill in the right fields....it won't connect and falls back to the values above...
Something wrong in the Exchange setup?

Hmm...found aguide here:
http://enterpriseit.co/microsoft-exchange/2013/ssl-certificate-request/
Though it doesn't mention anything that with the self-signed certs it won't allow Outlook 2013 to connect...
So from my point of view Outlook 2013 should be able to connect anyway...as during the connect process you can install the self-signed cert.....so must be something else then...

Outlook 2013 people pane is not showing any items for internal domain users. External contacts works fine

I have recently purchase a new PC which has Windows 8.1, and Outlook 2013, connected to an exchange 2010 SP3 RU4 server.
In the People pane, the for External clients, then this box populates correctly, but for internal domain users, it shows "There are no items to show in this view"
On my OLD PC using XP, and Outlook 2010, connected to the SAME account, then people pane shows correctly for all users.
Any help appreciated
regards
Chris

Hi Chris,
I have checked in my Windows 8 and Outlook 2013 with Exchange 2010 SP3 RU4 environment. There are three folders listed under My Contact in my People pane:
Contacts: The contacts which we added and saved
manually before.
Lync Contacts: The contacts we added in Lync.
Suggested contacts folder: Automatically
keeps track of everyone you send a message to, but isn’t in your Outlook contacts. Please note that it is different from Auto-Complete List.
Therefore, I suppose that the meaning of “but for internal domain users, it shows ‘There are no items to show in this view’ ” is that there is no contacts in the
Contacts folder. Is it right? If I misunderstand, please point it out. And we need to add and save users manually in this folder.
Thanks,

Notes are blank in Outlook 2013 after updating the note in IOS 8

The setup:
On my computer, Windows 7 and Outlook 2013 (Exchange 2013 on the server side).
I create a new note and close it. I can open it, modify it, and everything works as expected.
On my iPhone 6 with IOS 8.0.2, I go into the same note. Everything looks fine. If I modify it and close it, I can open it and everything looks fine.
Now the issue...When I go back to Outlook on my PC and open the same note (subject/title shows in the list view), the note is completely blank.
So, I go back to my phone and everything still looks ok. If I type in the now blank note on the PC, it overwrites the old note contents.
To make all this even stranger, if I log into OWA, the note is there and works fine through this entire process (well, until I overwrite the contents). But, in OWA, it seems to strip out the subject on certain saves.
I tried all this on another laptop I have lying around and get the same results. I tried a new profile. I tried safe mode. All the same.
This leads me to believe that Outlook 2013 has issues displaying notes. If OWA has the correct info, then the server has the correct info.
Does anyone else have this issue or can try to replicate the issue? Any suggestions on fixing it?

here)

See if you are hitting the issue mentioned in the article -> http://support2.microsoft.com/kb/2980834/en-us?sd=rss&spid=16662&wa=wsignin1.0
If yes, the fix is with Exchange Server 2013 CU6.

Outlook no resolving Exchange Server name , resolving another name like SID Object

Hello All ,
I Have Exchange 2013 installed on windows server 2012 , Outlook no resolving Exchange Server name , resolving another name like SID Object . Please see the attached file below .
how can fix the issue ?
Thank you

Hi,
Please run following command to verify whether the Outlook resolved the correct Exchange Server GUID:
Get-Mailbox MailboxName | FL name, ExchangeGUID
Following Screenshot is the test result in my lab, for your reference:
If we get the correct GUID, it means we have already connected to Exchange Server successfully.
The GUID format for the server name in Exchange 2013 is an expected behavior.
Found a similar thread for your reference:

Outlook 2013 with Exchange 2010

we upgraded from Outlook 2010 to 2013 x64it and the exchange server is the same 2010
when trying to cleanup public folders the Clean Up tool is grayed our and it says "outlook 2013 this feature is not available because you are running in online mode and connected to microsoft exchange server 2007 or earlier" none of this is true.
It works fine when you are in your own inbox, only grays out in Public folders, this worked fine with Outlook 2010
David

Hi David,
Sorry for the late reply.
Since Outlook 2010 works well, just Outlook 2013 has this issue, I still believe this issue related to the Outlook 2013 Client side.
I suggest also create a thread on Outlook Forum so that we can get more professional suggestions.
For your convenience:
https://social.technet.microsoft.com/Forums/office/en-US/home?forum=outlook
If this issue really related to the Exchange 2010 server side, I suggest re-setting the default public folder database for testing.
Please make a back up for the current setting in case of some crash. If it doesn't work, please back to the current setting.
Then please follow following article to change the default public folder database:
Change the Default Public Folder Database for a Mailbox Database

Outlook 2013 with Exchange 2013 keeps giving read receipts

Hello experts,
We have an Exchange 2013 server. All users are joint to the domain, except one user (Windows 8.1) which is in a Workgroup, and using Outlook 2013 with IMAP protocol.
This particular user is having a problem. When he send's any email from Outlook and requests a read receipt, after that he keeps getting hundreds of read receipts in his inbox. I have tried disabling (for temporarily) the Windows server 2012 firewall, but
still having the same issue.
Is this a known bug in Outlook 2013 with Exchange 2013? Any help troubleshooting this?

Hi,
According to your description, I understand that IMPA account get hundreds of read receipts while he requests a read receipt.
If I misunderstand you concern, please do not hesitate to let me know.
Whether are all account or some special user experience this question? Please do a test in external with IMAP account to double confirm.
How about the “Request a Delivery Receipt”?
Also, please run message tracking log to get more details about message mail flow:
Get-MessageTrackingLog –Server “mailbox server” –Sender “[email protected]” –Recipient “[email protected]” –MessageSubject “Read: message subject” | Select Timestamp, ClientHostname,ServerHostname,Source,EventID,Recipients,RecipientStatus,Sender | ConvertTo-Html > “C:\Test\Test.xml”

Outlook 2013 Free/Busy can not retrieve information

Currently have a problem with Outlook 2013 Free/Busy can not retrieve information.
All windows updates are installed.
Exchange 2007 is being used.
Problem started last week.
Already Tried without any progress:
1) Recreated profile (Fixed the issue for 1 week)
2) Cleanfreebusy ( No longer works for outlook 2013)
3) /Cleanreminders
4) Removed latest updates for outlook 10/02( As requested by Microsoft support, however we found users without this update installed, suffering from the problem)
5) Repaired OST file
6) Repaired Office 2013
Can anyone help it would be much appreciated?

Hi
As per the information and details provided by you, Outlook 2013 free/busy cannot retrieve information, please follow these steps: -
The user has never logged in
Before any free/busy information is available, the user must have at least a calendar. A calendar will not be created until a user logs into their account.
The option to publish at some location has been enabled in Calendar options
In all Outlook versions, the option to publish free/busy information must be unchecked. By default, this option is already unchecked.
This option is located under
Tools > Options > Preferences > Calendar Options > Free/busy Options.
Outlook is using cached browser information
Outlook Free/busy user HTTP, and therefore borrows information cached by Internet Explorer. It is required to clear the offline cache. This is located under
Tools > Internet Options > General. In the “Temporary Internet Files” section, choose the
“ Delete files” button.
Internet Explorer settings is not correct
AN Internet Explorer setting may prevent the .ics file from downloading via HTTPS. In Internet Exporer on the Outlook computer, go to
Tools > Internet Options > Advanced. In the Security section, the checkbox for “Do not save encrypted pages to disk” should be unchecked.
I hope this information will be helpful for you.

Exchange Server not responding - please try later

Hi there
Can anyone please help with my E75.
I have had the phone over a year and since day 1 it has syncd perfectly well with my Outlook at work.
Until a couple of days ago!!!
Since then, it has refused to sync my calendar and contacts. It is still syncing e mail but about half way through the syncing process (once it has synced the e mails) I get the error message “exchange server not responding – please try later”.
I have asked my work IT helpdesk but they have said speak to the mobile provider. They also said there’s nothing wrong with their servers but I got the feeling they hadn’t really checked.
My problem is that I don’t know where to start.
Is the problem to do with:-
My phone?
Its settings?
Orange’s servers?
My work’s servers?
Nokia’s servers?
I’m confused – please help.
Ps I can’t believe it is my phone's settings as I haven’t changed these and it worked fine for a year. And, anyway, my credentials must be ok because it is still syncing my e mails.
Thanks in advance
Ian

Problem appearing olders emails outlook 2013 with Exchange 2007 SP2

hi everyone,
recently i have problem with user mailbox OST more than 20 Gb (configured with outlook 2013 and exchange 2007 SP2 ) and if i scroll down in the olders mails in the Inbox Folder it's stoped in 2011 but i have more than this year ! i tried to add regedit keys
such as Maxlargesize... and no changes and tried also with exporting this ost to PST File (i proceed with computer 32 bits ....) and always stop in 2011
Please if you have ideas to resolve this
best regards
vote if you think useful

Hi,
OST file is a local copy of your email messages, calendar, and other items that are on the Exchange server, it is always synchronized with the items on the server. So, the first thing we need to check is to login to OWA and check if you can see older
emails from there.
If you can't see the old email from OWA, it means the emails are removed from the server. In this case, you'll need to contact your Exchange admin to see if your old emails are archived. We can also check if you have enabled AutoArchive feature in your Outlook,
which may move your emails from your OST file to a local PST file. See:
https://support.microsoft.com/kb/830119?wa=wsignin1.0
If you can see the old emails from OWA, your OST file may be corrupt. We can exit Outlook, find the .OST file and rename it to .old, and then restart Outlook to let it sync a new one. By default, the OST file are save in:
drive:\Users\%username%\AppData\Local\Microsoft\Outlook
Please let me know the result.

Outlook 2013 with Exchange 2007 - out of office problem

We are using outlook 2013 with Exchange 2007. When users select their out of office it will work fine for the first day, however there after the Out of Office replies stop working. Out of Office is set correctly within Outlook, but what we have found
is that if the user opens Outlook the Out of Office starts to work again. Also when the user opens Outlook it takes around two minutes before it registers that Out of Office is on.
Any Ideas?

Hi,
How do you configure your OOF? From standard OOF wizard or define an automatic reply template from Rule wizard?
If you are using a template, Outlook must be running for the Rules Wizard to automatically reply. Please refer to the Note in the following KB:
http://support.microsoft.com/kb/311107
If it is configured by using standard Out of Office assistance in File > Automatic Replies, please remove OOF settings in Outlook and set it from OWA 2007, then check whether the issue can be reproduced.
