After Migrating To Exchange 2013 All Outlook 2010 Users Constantly Prompted For Password (BUT OUTLOOK WORKS).

I have two servers. One is Exchange 2010 and the other is Exchange 2013.
Three of our users had mailboxes on Exchange 2013 for the last few weeks with no problems. They used Outlook 2013 and Outlook 2010. After moving the rest of our ~25 users to Exchange 2013 the users with Outlook 2010 began to be prompted for their
password constantly.
They try entering it and it immediately reappears.
The odd thing is it shows connected and they are able to send and receive emails correctly.
I've tested our exchange connectivity using www.testexchangeconnectivity.com and all is well there.
I'm not really sure what's going on.
Any help is appreciated.
Luke
Thanks, Luke Pickard

This can appear if Outlook clients are trying to connect to OAB virtual directory, and don't succeed for some reason. Mailbox and mailflow will work, but password prompt will appear when Outlook tries to contact OAB. Try to investigate in that direction.
Also, perform Outlook Configuration test (right click Outlook icon in task bar while holding CTRL and select Test email autoconfiguration.

After migration to Exchange 2013 the old outlook clients do not automatically reconfigure

After migration to Exchange 2013 the old outlook clients do not automatically reconfigure
we use outlook 2013

Hi ,
I hope you would be having exchange 2013 coexistence environment with exchange 2010 or 2007.
Autodiscover is the feature which will make the outlook profiles to configure automatically.So please make sure the following things are in place.
1.Autodiscover record on the internal dns need to be configured and it has to be resolved properly to the cas servers or else to the LB if you have.
2.Please check the autodiscover internal url.
get-clientaccessserver -identity "server name" | fl *internaluri*
3.Make sure the name used for the autodisocver and internal outlook anywhere are available on the SAN certificate installed in exchange.Same time we need to enable the installed SAN certificate for the exchange services like iis,pop,imap,smtp.
4.You need to have the autodicover name and internal outlook anywhere name on the internet explorer proxy exceptions when you have proxy servers available on your network for internet access.
Note : moreover we need an additional information's from your side about your environment.
Thanks & Regards S.Nithyanandham

Office 365 Outlook prompts for password whenever outlook is restarted.

Hello Folks,
We have recently deployed Office 365 (We had Kerio email system previously, But we did not do a migration).
The problem is
Office 365 Outlook prompts for password whenever outlook is restarted
Tried the following workarounds,
1) Logon network security under More
Settings on the Microsoft Exchange Security tab
is set to a value other than Anonymous Authentication
2) Tried removing the Generic Credentials from Credential manager.
The is issue is only for some users (Majority).
(OS Platform: Windows 7/Windows 8).
Thanks in Advance

The first thing I would recommend to do is to make sure that your install missing Outlook updates and try again.
I would also recommend asking them in this forum: https://social.technet.microsoft.com/Forums/en-US/home?forum=outlook

Users cannot access calenders from outlook after migration to exchange 2013

I have a strange situation after upgrading to exchange 2013 some users are reporting that they cannot open or create calender appointments for calenders they used to be able to manage. we currently are using outlook 2010. also when the users access the calenders
with the webmail they are reporting that they can access the calenders and are able to do all the things they need to do.
i have tried reinstalling office and adding their exchange accounts but this does not help.
another stange thing is that to be sure i had setup the correct access policy i have reset all the security entries on all the calendars with the help of powershell. this seemed to have helped but after a couple of hours some users started reporting that they
could not access calendar items again!

Hi,
Is there any error description when the problematic users cannot open or create calendar items? Since the issue only happens to some users instead of all users and all calendars can work well in OWA, I think the calendar in the mailbox
should be configured properly.
Please configure the problematic user’s Outlook account in a clean computer with new installed Outlook to check whether the issue persists.
Thanks,

Outlook 2007 on Terminal Server cannot manage Public Folder Favorites after Migration to Exchange 2013

Hi,
we are running a Server 2008 R2 as a Terminal Server with Outlook 2007 SP3 (incl Nov 2012 Update 12.0.6665.5000) which is known as fully supported with Exchange 2013.
With Exchange Server 2007 we did not have any issues. But after having successfully migrated to Exchange 2013 we cannot manage our public folders favorites from these clients anymore.
As we are running Outlook 2007 on a WTS we can not use Exchange Cache Mode and so we can also not download Public-Folders-Favorites as an option. Whenever we try to delete existing favorites or when we try to delete public folders with content or subfolders
there will be an error msg that says that it cannot be deleted and that there may be no sufficient permissions. But this IS NOT the issue NOR the solution as I have full admin rights and am owner of the public folders.
On single fat clients with Outlook 2007 with Exchange Cache Mode enabled we can manage the favorites and the public folders without problem.
We need to be able to manage the favorites of all users (circa 50-60 users) from the WTS with Outlookm 2007. I have no more ideas right now. Does anyone know how to get this settled?
Thanks, Paula

Hi,
Based on the description, users could access public folders successfully, but when they tried to manage public folder favorites or wanted to remove specified folders, they got error message of no sufficient permissions.
Is it right?
You mentioned on single fat clients with Outlook 2007 with Exchange Cache Mode enabled, user can operate normally. Is this a WTS with Outlook 2007 installed?
If possible, please switch this Outlook client from cached mode to online mode to check result.

Exchange 2013/2010 Co-existance Outlook Users Always Prompted for Password

Hello,
We are in the process of attempting to migrate to Exchange 2013, but during the migration time, we need to coexist with the two versions. Our outlook clients are a mix of Office 2007, 2010, and 2013. When a user is migrated from 2010 to 2013,
they start getting prompted for their password in Outlook every few minutes. They can click cancel and continue working, but they continue to get prompts for their password. If they click the update folder button in outlook, it updates fine, and
the password prompt goes away for awhile.
Most topics on this state that this is caused by a certificate issue. We have an internally deployed CA, with the Root certificate trusted by all clients. The exchange 2013 server has a certificate that was created by this CA.
I believe that this is caused by OAB (address book) still being hosted on the Exchange 2010 server (with a self signed cert), that is causing the connection to fail. Is there anyway to test this without breaking outlook connections for the users that
are on Exchange 2010? Or is there any other reason that this would occur?
Thanks for any assistance.

Sorry for taking so long to reply, other items came up that rank higher then this migration.
I ran the Test-OutlookWebServices CMD and got this result:
[PS] C:\Windows\system32> Test-OutlookWebServices
Source                              ServiceEndpoint

I
am currently thinking that this may be the error. Is there a way to
change the first failing result to the hostname of the
exchange13.company.local without breaking the current settings for the
exchange10.company.local autodiscover?

Mailbox sizes increase dramatically after migration to exchange 2013

After I migrate mailboxes from exchange 2010 mailbox to 2013, the size increases.
For example -
On exchange 2010 I run get-mailboxstatistics: TotalItemSize : 6.706 GB
On exchange 2013: TotalItemSize : 9.374 GB
Anand_N

Hi Anand,
Please note that the actual space used by the mailbox database will not increase. This only refers to the attribution of space used by each individual mailbox. Actually, this happens due to the inclusion of all item properties into quota calculations, providing
a more accurate computation of space consumed by items within their mailbox. However, you can adjust mailbox size and increase mailbox quota by 40% before moving.
You can follow below cmdlet in order to increase "ProhibitSendQuota" value for all users that are not using the database quota defaults:
Get-Mailbox -ResultSize Unlimited -Filter {UseDatabaseQuotaDefaults -eq $False} |
Where {$_.ProhibitSendQuota -ne "unlimited"} | ForEach {Set-Mailbox $_ -ProhibitSendQuota "$($($_.ProhibitSendQuota).Value.ToMB() * 1.4)MB" -WhatIf}
You can have a look on this link to prevent the cause :
Mailbox migration from 2010 to 2013
Hope, this will be helpful for you.

ActiveSync Failures After Migration to Exchange 2013

Hi all,
I am having an issue with ActiveSync a single mailbox that has been migrated from Exchange 2007 to 2013. After the mailbox was migrated to 2013 it continued to sync as normal for a week or so. After removing the exchange 2007 server (uninstalled exchange) from
the topology, the user could no longer sync.
This is not the inherit permissions in AD issue. I had a user with that issue but this one is different.
It appears to have something to do with the app pools. The following article provides a script to recycle the app pools, when I run this, the issue is resolved but only temporarily. Within 20 mins or so, the issue returns for the user. Running the script
again works but again, it is only temporary.
http://www.expta.com/2014/04/fix-for-exchange-activesync-failures.html
Can anyone tell me why this fix only works momentarily? Is there any way (besides running the script constantly) to make the fix stick?
Any help is much appreciated.
Thanks!

Instead of restarting App pool, I would suggest looking at the IIS logs on the Client Access Server and check for the entries for this user.
If you notice either throttling/something wrong with this user's connection, troubleshoot in that direction.
also look at Event logs to see if there are any problems with App pools creating Watson dumps. (event ID 4999, 1003 etc)

Outlook 2013 / Exchange 2010 constantly prompting for password

I as well as many users keep getting prompted for User/pass in outlook. This usually happens when I go from LAN to WIFI or from office to home. For example, If I close my laptop (not shut down) and head home then log back in and connect to my
VPN I usually get prompted for my user/pass for outlook. I type the correct user/pass but it does not accept and immeadiatly prompts for me to re enter. If I close down Outlook and re open the issue is fixed however this is not fixing this issue
and the owner of the company is receiving this error as well. I would like to find a solution so that either it does not prompt and automatically updates once it is reconnected with the network via VPN.
Any suggestions?
Thank you

Outlook is simply not good at that with the existing protocols in Exchange 2010. Exchange 2013 uses MAPI over HTTP which may make that experience better.
Switching networks with Outlook open is typically not a good user experience.

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.

After specifying the external host name under outlook anywhere, users pop up for password

Dear All,
I have installed and configured exchange 2013 as a fresh installation on server 2012 and it worked fine till i changed
specifying the external host name under outlook anywhere(in exchange ECP -> Server -> server -> W12R2-Email2013).
My internal domain is starnavigator.lk and we have several accepted domains listed. but all the staff checked web mail through
mail.leoburnett.lk internally and externally. even now web mail is working fine.
After i added external host name as mail.leoburnett.lk
all the internal PCs start to pop up for user name and password and its not connecting.
even if I reversed back the settings, still prompt for user name and password. also auto discover cant locate the settings. if i configure the settings manually, i t works for first time and after restarting outlook, again prompt for name and password.Any
any advice or solution please??
Thx,
Dulana

Run this tool and post the result (only errors)
https://testconnectivity.microsoft.com/
After configuring outlook manually, run Test E-Mail Autoconfiguration and Connection Status and post the result.
Editing just an URL for OA shouldn't cause any issue.
Did you restarted IIS Service?

Outlook Clients for Exchange 2013 Prompt for Password

I have a co-existence of versions 2007 and Exchange Server 2013 CU2 and currently have the following problem:
- Customers now where I performed the migration to the 2013 version, when starting Outlook is always asking for password. The settings for Outlook Anywhere are as follows:
RunspaceId : b43cd829-a81f-4b00-bb4d-73389c9df50d
ServerName : EXCH-HTCA13
SSLOffloading : False
ExternalHostname : webmail.first.pt
InternalHostname : exch-htca13.first.pt
ExternalClientAuthenticationMethod : Basic
InternalClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Basic, Ntlm, Negotiate}
XropUrl :
ExternalClientsRequireSsl : True
InternalClientsRequireSsl : True
Can anyone help me identify the problem?

Hi,
Agree with Andy,you can change the ExternalClientAuthenticationMethod to NTLM,
In addition, I recommend you refer to the following article:

Outlook 2010 prompting for password

Hi everybody. I ran into an issue yesterday morning where at one of our sites Outlook 2010 has started prompting for a username and password. If the user types in their username as "MYDOMAIN\myuser" and their password, it lets them in but the Exchange
status shows as "Disconnected". If the user sets their username to just "myuser" without the domain on the front it lets them in and works as expected until they close Outlook, at which point they have to enter their credentials again.
The strangest thing about this is that it's only affecting one of our sites and only Outlook 2010. Users running 2007 and 2003 do not have the problem and only users at this physical location have the problem. Does anybody know where I can look? I have tried
clearing stored credentials, created new Outlook profiles and reset passwords. None of these things seem to have had any effect.

After changing a ton of outlook settings, deleting the user's account profile on outlook, deleting their domain profile from the effected computer, trying to fix the registry, deleting stored credentials, etc.... almost everything else I found something
that FINALLY worked for me after over a year and about 12 different users being effected.
in the past I would just give up after much frustration and upgrade them to Office 2013 but that gets very expensive especially when I have 57 other users that could potentially run into the same issue.
Here is what I did.
- back up the user's data. log out and log into local admin
- delete the user from the local registry
- repair Office 2010 through control panel/programs, restart
- have user log back in with their credentials to make new local profile. recover their backed up documents. log out and log back in as local admin.
- install hotfix KB2597011
- restart computer
- install hotfix KB2583935
-restart computer
- log in, open outlook and setup user's account.
Some of these steps may be skipped as I didn't find the hot-fixes until after I repaired office, however I am just providing what I did in the process to end up with a working outlook again.
Some things unique to my situation that may or may not help.
- I noticed some of the computers have Office2010 32bit installed on 64 bit machines.
- Some of the users were swapped over using a profile mover program when we moved to a domain environment.
- For me this always happens when the user's passwords expire and they have to log in to the portal to change it. Then outlook starts with the repeated prompt for passwords. It is always computer specific and nothing but what I provided above has worked
other than re installing windows 7 and then office or upgrading to office 2013.

Outlook 2007 Clients Prompt For Password When Opening

I am running Exchange 2007 Standard. New outlook 07 clients prompt for password each time it is opened. Older clients do not prompt for password. Is there any way for outlook 07 to not prompt for password? Users already logged into domain, should their credentials not be recognized automatically like with outlook 03?

This fixed it for me.

Same problem here after restarting SBS 2008 for upgrades (annoying login box popping up after starting Outlook and also other times).
This solved the problem for me:
IIS Mgr on SBS 2008 / - / SBS Web Applications /
- SSL Settings / Client certificates - Stop / Start web server after changing settings:
Autodiscover: Ignore
EWS: Ignore
OAB: Accept *)
owa: Accept *)
Rpc: Accept *)
RpcWithCert: Accept *)
*) All these have to be Accept to get rid of login box
Best regards

I was having the same issue. SBS2008, Exchange 2007. Only being prompted in Outlook 2007 clients. Tried a lot of different things to fix it, but none worked. This started happening after a round of security updates but I could not find KB2412171 on the list.

Prompted for password after the PO is restarted

Hello everybody,
Some users are prompted for password on the device after the Post Office is restarted.
Killing the app "Mail" on the iDevice seems to resolve the problem. Do you have another solutions to avoid to kill the app.
Thx
