Exchange 2010: Autodiscover Problem After Public IP Address Change

$
0
0

We recently changed our public IP addresses, and now mobile email apps no longer work while away from the network. I updated our external DNS host to include two new A records for mail and autodiscover, so outgoing and incoming emails are coming through fine within the network. 

We use Exchange 2010 and Windows Server 2012; both are behind a SonicWall firewall. I have updated the local DNS records and the firewall accordingly. The X1 (primary) and X2 (backup) interfaces reflect the new IP address info. I also created new public_mail and private_mail address objects. 

I used the Microsoft Remote Connectivity Analyzer and found that autodiscover is not working (pasted below). It looks like port 443 is not listening/opening. However, I am not sure why. It is configured to open. Any help is much appreciated. Please let me know if you need more information regarding the problem.

Thanks,

Kevin

Tls 1.2 on Exchange 2010

Hello,

I have a server with Exchange 2010 SP 3 Rollup 29 with all the roles. I have added a wildcard certificate and IIS-OWA works for me; but I don't get him to send the emails with TLS1.2. I have disabled TLS 1.0 and TLS 1.1; but send me all emails with TLS 1.0; Is it because I send it from the OWA? Thank you

Logging file size estimation for Exchange 2016

$
0
0

Hello all,

I was wondering what the logging file size estimation for a year would be for a 2016 Exchange server with 300 Mailboxes and around maybe 50 Messages per user a day. With high times being 8-4 With maybe 70 or so users being very active, I wouldn't say all 300 users send the 50 per day maybe just the 70 highly active. We have some users that may send twice a week, any who I am moving from Exchange 2010 fairly soon. With two servers in the DAG and 5 DB's in the server, my CIO wants to know if we could supply the server with the storage to hold our log files for a year. While the excel sheet that calculates is useful it only shows storage of logs per Server, DAG, Environment not per day, week, month, year total unless there is a field I am overlooking.

Thanks!  

Exchange 2010 to O365 changing from Cut-over to Hybrid

I have one site that I started with a cut-over migration but now I am thinking that I need more time since I am migrating 70 users. Is there going to be some issues changing from one to the other? About 75% of the mailboxes are confirmed copied but we can't make that cut-over in one or two days. If it can be switched without issues, then great. I didn't want to do anything until I heard back from someone that has done this before.

I already those soltutions:

1. Go into IIS manager
2. go to the servername (Global configuration)
3. Go into Modules
4. Lookfor exppw - it might exist, just remove it :-)
5. Select "Configure NAtive Module"
6. In the dialog - select Register, type "exppw" as Name
7. Click the browse button for Path, and browse to f.ek. "c:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\Auth\" and Select exppw.dll
8. Press okey and okey - the exppw should be in the list Again, for Exchange Setup to remove :-)
9. re-run setup to uninstall Exchange 2010, and it should now run without problems.

And tried with another  file :C:\Windows\System32\inetsrv\config\applicationHost.config

Could you please give me some help?

Exchange 2010 Hybrid Public Folders 365 confused about what the (Configure directory synchronization) actually does

$
0
0
Can someone please better summarize what this step actually does?

I ran the powershell script with -WhatIf and I can see it is checking/pulling from Objects that are in AD under 'Microsoft Exchange System Objects'

But I don't understand what these scripts are actually doing and when/why they need to be run daily, what changes are they trying to Sync?

-------
Configure Exchange Server public folders for a hybrid deployment
Step 2: Configure directory synchronization

The Directory Synchronization service doesn't synchronize mail-enabled public folders. Running the following script will synchronize the mail-enabled public folders across premises and Office 365. Special permissions assigned to mail-enabled public folders will need to be recreated in the cloud since cross-premise permission are not supported in Hybrid Deployment scenarios. For more information, see Exchange Server Hybrid Deployment.

 Note

Synchronized mail-enabled public folders will appear as mail contact objects for mail flow purposes and will not be viewable in the Exchange admin center. See the Get-MailPublicFolder command. To recreate the SendAs permissions in the cloud, use the Add-RecipientPermission command.

On Exchange Server, run the following command to synchronize mail-enabled public folders from your local on-premises Active Directory to O365.

Sync-MailPublicFolders.ps1 -Credential (Get-Credential) -CsvSummaryFile:sync_summary.csv
Where Credential is your Office 365 username and password, and CsvSummaryFile is the path to where you would like to log synchronization operations and errors, in .csv format.

 Note

Before running the script, we recommend that you first simulate the actions that the script would take in your environment by running it as described above with the -WhatIf parameter. > We also recommend that you run this script daily to synchronize your mail-enabled public folders.






CAS Proxying on Exchange 2010 for some users while migrating mailboxes

$
0
0

Hi,

We're moving mailboxes from an AD site to mailbox servers on another site and this will take about weeks of time.

OAW and OWA are published via TMG and point to a cas server in current site to all work well.

Normally when some users are moved to mailbox on new site with a new Non-Internet facing (better to say not published by TMG) they cannot connect from outside. As I said this will take about a month to move all the mailboxes so I'd like this:

When a user tries to connect from outside it will go to current CAS and mailbox server whose mailbox may be or may not be there. If there so .. serve and have fun but if his/her mailbox was not found on mailbox servers on that site (It may be moved) then I want the fallback from exchange side to proxy the OWA/OAW and ActiveSync requests to the CAS on the other site.

Is this possible?

Thanks in advance.

Exchange 2010 - Add Forest in 2010 consol with MFA enabled

Hi, 

Issue with adding forest to 2010 consol after MFA is enabled. 

Sorry for posting this in a Exchange 2013 forum, but i couldn't find anything related to 2010 :) Please do delete or move if this is the wrong place. 

After MFA was enabled the forest disappeared from the 2010 consol. Adding it give error message with authentication failure. 

I found that the Microsoft Exchange Online Powershell Module should solve this (In Exchange 2013 the module is downloaded from the server - hybrid page) 

Since this is an older Exchange version and older Powershell i am afraid that the Exchange Management Shell will stop working due to changing the authentication. 

Does anyone have any inputs or can advise ?

I have been told by one of our program suppliers that my exchange server is not configured correctly to accept mail from their program. I have no ideal what is wrong. I have sent a e-mail from the iseries to myself and this is what I see in the receive connector log  called iseries. I also send to a gmail account and they accept the mail. So i have tested it both externally and internally I say it works.

195-minute delay?

Exchange 2010 SP3 UR4 (yes, SP3 UR4!) single-server using EOP as its smarthost.

This server has a problem...it fails to install UR's, which is why it's still on UR4. So we're in the process of migrating to a new single-server EX2010 SP3 UR29 so we can then set up hybrid Exchange and migrate to Office 365 before end-of-support.

There's no EX2010-to-EX2010 migration guidance that I could find. I was referred on another thread here to https://docs.microsoft.com/en-us/exchange/checklist-upgrade-from-exchange-2010-exchange-2013-help, and instructed to do the EX2013-side tasks using EX2010 MMC/PowerShell equivalents and I'd be fine.

So I got as far as step 14, Configure service connection point, which sends youhere--

https://docs.microsoft.com/en-us/exchange/exchange-2013-client-access-server-configuration-exchange-2013-help

--matching config of the old EX2010 throughout, and users started reporting that outbound emails sent in the last 2 hours (a bit after I started configuring the new EX2010) were not being received.

I remembered then that the perimeter firewall blocks outbound SMTP for all internal IPs except that of the mail server. So I modified that rule to add the IP of the new EX2010 to the allow list, thinking it would solve the problem. I'm not sure that it didn't, honestly, but it was late in the day and I couldn't take any chances because I wouldn't be there next day, so I shut down the new EX2010. A test message sent after the shutdown was delivered timely. I expected a flood of outbound messages queued during the outage to be delivered, possibly after a short delay...but they were not. They all arrived in a rush almost 3.5 hours later, and 5.5 hours after they were sent.

Message Tracking Logs on the old EX2010 show they were sent off to EOP as they were received by the server (i.e, up to 5.5 hours after they were sent) and all about the same time that I received them, so that starts to sound like a CAS problem. EOP message traces show "There was a delay of 195 minutes prior to being received by Office 365," but shows no delays after receipt and before sending on to my server (on O365, and also no delay in the O365 trace). The delay for the particular message was actually longer than 195 seconds/3.6 hours...it was about 5.5 hours. So I don't understand that, either.

The new EX2010 has been shut down ever since, and there have been no further mail flow problems during that time.

But I don't really understand what happened, or if the firewall rule blocking outbound SMTP explains all the symptoms--

  • The firewall blocked outbound SMTP for about 2 hours.
  • There might have been outbound emails numbering in the low 100s queued--I should have looked at the queues at the time but I didn't--but with a 30Mbps upstream, the queues should have cleared fairly quickly...minutes, not hours. As it was, 8 or 10 queued emails for my external mailbox were delivered within 2 minutes of each other.
  • Nothing I know of would have prevented the old mail server from sending messages at any time, but nothing went out. App logs on the old EX2010 showed nothing unusual.

Ultimately, I'll boot up the new server after hours and do some mail flow tests. Before doing that though, if possible, I'd like to understand what happened so I have some idea if this was just caused by the outbound firewall rule, and therefore likely to be resolved at this time.


Refresh newly-managed mailbox

Is there a way to speed the process of having "Manage Full Access Permission" take effect? That is, when I add an Exchange user to the "Manage Full Access Permission" list on the Exchange 2010 server, it can take five to 10 minutes before the newly-managed mailbox appears in the folder list for the user granted the full access permission to the mailbox.

I am not sure if this is even primarily an Outlook question or an Exchange question.

Change RPCClientAccess Server automatically after changind databases CAS servers

Hi,

while setting up outlook for some clients, their mailboxes had been in a Database Say DB1

So outlook has set this as the exchange server

Now they are moved to another Database in another site with another CAS server, So, the CAS server for the databases was updated using set-mailboxdatabase -rpcclientaccessarray to the new CAS.

But thus setting is not reflected (changed, updated anything ) in clients outlook. How this should be handled?

Recreating outlook profile is a baaad idea cause there are too many of them.

And BTW, how and where in outlook 2016 we can see or change exchange server settings?

In outlook 2010 it can be seen in email accounts and can be changed there. In 2013 seen there but no change possible and in 2016 I cannot even find where and what is the server set let alone changing it. It just displays username.

Regards
