ok, so I'm brand spankin' new to EOP. we have a few services run by our security team that send emails from outside using internal email addresses. with our Barracuda, it was easy enough to allow them through and not be tagged. EOP is tagging these messages with "This sender failed our fraud detection checks......". I added the ip for the server issuing these to the connection filter ip allow lst in o365 admin center (EAC/protection/connection filter/default/connection filtering/ip allow list). should I be doing this elsewhere?

any pointers would be appreciated.

I tried re-adding database but it is showing already member of that server and "Database" and "Context state" State is UNKNOWN.

Good morning,

I set up a new Exchange 2016 server and I move all my mailbox from my Exchange 2010 server to the Exchange 2016 server.
All work fine but I have a lot of log for the Database (E010000685A.log, ...) and it use all the space :-( How can I remove them or do something so that that uses less space?

Thank you so much for your help.
Best Regards

About a year ago I decided to move us from Exchange 2010 On-Prem to Exchange Online.  Due to some peculiar circumstances, I had to go to Exchange Hybrid first (keeping my Exchange 2010 On-Prem) until I could wrap up a few user accounts.  I'm now ready to go ahead and finish migrating to Exchange Hybrid, fully getting rid of Exchange On-Prem.

However, the last MS rep I spoke with stated that due to having a local AD, I need to keep the On-Prem Exchange server but couldn't give me a good reason.  

I really would like to be fully Exchange On-Line and am looking for opinions/thoughts from others.  Do I need to retain the On-Prem Exchange server?  Can I decom it with minimal issues?  If so, any recommendations for the best path to do this?

TIA.

I've got my primary Email for work, then I've added a shared mailbox to outlook.  I can only Sign / Encrypt from my Primary email using my CAC, I've disabled cert mismatch in the registry not sure what else to try.  When sending a message how do I make a selection, to send from one email address instead of the other. We use Outlook 2013,  I've been granted Full Access to this mailbox.

We have exchange 2010 expiring and I Just renewed it on Certificate for Exchange website and they regenerated new certificate with updated dates.
 I was able to import intermediate certificate, but I can’t import or renew certificate in Exchange management   console with CRT file supplied.
If I do import it ask me for a private key which I don’t have and if I create new CSR request and try to complete pending request its giving me an error “cannot import certificate as certificate with current thumbprint already exists.
What is the easiest and safest way to update certificate without any down time?
PS I do have many protocols and autodiscover and few other items listed on my current one I and don’t remember all the details of my current one

Syncing on prem to office 365 via adconnect and migrating mailboxes to exchange online in the cloud.  I have a couple of questions:

1.  If I migrate a users mailbox, and the user does not have a license in Office 365, will the user still migrate and have full functionality with the migrated mailbox for 30 days?  After 30 days, would this go to the recycle bin and need to be restored?

2.  I am assigning licenses through msol by using a on premises group, then have a script that reads the group and if a member set's license sku's in O365.  On some occasions (small amount), the license is added to the group, and the script goes to set a license sku but this fails.  I think this is due to giving a license to the user at some point, then taking it away.  Does giving a license set any attributes in msol which would cause this?

3.  I set a SIP address for skype for business for on prem mailboxes and accounts that are syncing to O365.  I've noticed when some accounts were migrated, that skype connection was lost and I had to re-license the user.  Any explanation why this would happen.

Really appreciate any knowledge on this.

Thanks

I have a scenario where organization was setup in O365 and Azure AD and now wants to have onprem AD and file services, what is the best way to migrate Azure AD  to onpremise AD. Once complete, i would expect to have some form of sync between onprem and O365, they will still use exchange online.

The can onprem AD ( Server 2016) be populated from Azure using AADconnect writeback, has anyone done this? please share

I have an Exchange Server 2010 that is currently running activesync and 3 phones are syncing with it.  The server name and the SSL certificate all references the firms old domain name.  I set this up 4 years ago with the assistance of paid for technical support and have forgotten most of what we had to do.  I have googled articles about it but have not found anything that goes into details.  Does anyone have a link to a good set of instructions for modifying or setting it up?

Greetings,

I'm not sure if this is possible but here's my situation:
We have several external users, that have Active Directory accounts set up on our domain to access an internal web app:  For the purpose of the posting I'll call our domain:  domain.com.  
Their primary email accounts reside on another domain:  (i.e.  consultants.com)    I set them up with Active Directory accounts on our domain and associated their external email address to their AD account, 'MailUser' accounts.

My question is, when accessing owa with their AD account, they see a message: (and I believe this is expected behavior being the user is a MailUser and not a Mailbox User):

    "The Outlook Web App address https://owa.domain.com/owa is out of date."

Is there a way for me to set this MailUser account up to access the "domain.com" email address using outlook web app?  I'm thinking I already know the answer, which is No, because it's not a Mailbox user, but a MailUser and the 'Mailbox Features' such as Outlook Web App are not available to MailUser accounts.

Unless, someone has come up with a work-around, which is the reason for my post.

Thank you,

I am creating a mail enabled list in sharepoint which creates a contact in exchange. I have done this for several lists without issue.
Today I have created a new contact via sharepoint and when I trying to send an email from external to the list my emails are failing on routing with the error message
"Fail"
LED=550 5.7.136 RESOLVER.RST.SenderNotAuthenticatedForRecipient; authentication required; Delivery restriction check failed because the sender was not authenticated when sending to this recipient
Now I know I need to set permissions for distribution groups but there is no such option for contacts that I can see.
Internal users can send emails without issue.
I have tried looking through a working contact and this one but I cant see anything. Hopefully its something with me being stupid and missing something obvious. Does anyone have any ideas what could cause this?

Windows 10, Microsoft Office 2016 - Outlook 2016

problem
I need to easily insert emoticons into email messages with just a couple of clicks.

attempted solutions
  • Just typing :-) or :-( etc. works and turns into tiny icons, but that's only a small set of emoticons. I need more.
  • Using Add-ins from the Store is not available. I don't have an Exchange server, just IMAP, so I can't use the Store. The Store button is grayed-out.

suggestions
  • I see there is a way to add add-ins from File > Options > Add-ins, but I have to have a file. Where can I find add-ins that work this way?
  • I might be OK with some third party software that just lets me put emoticons into the clipboard and paste them from there, but I can't find anything of this sort that would allow me to get this done in just a couple of clicks.

Please, help. Thank you.

Hi all,

Attempting an on-premise (Exchange 2013 CU 17) to Office 365 hybrid migration. Here are the particulars:

* on-premise uses Barracuda cloud email security. MX records all pointed to Barracuda
* Firewall rules updated to allow on-premise Exchange to communicate with 365 Worldwide IP blocks
* 200 +/- email boxes
* ran hybrid config wizard on on-premise Exchange. Finished successfully
* Azure AD connect working as expected (created duplicate accounts in existing Office 365 environment, but can deal with that later)
* migrated my personal mailbox to 365, finished successfully. Shows as type "Office 365" in on-premise recipients section
*authentication working as expected across both systems

My migrated mailbox can receive internal-originated mail. Cannot receive external mail.

I'm leaning in the direction of connector problem. Considered Barracuda, but not sure if on-premise to 365 mail relay would even go through Barracuda.

Fortunately, I only have one bad mailbox (mine), but completely stalled now. Any help appreciated.

Disaster Recovery as a Service is one go-to solution that revolutionizes DR planning. Implementing DRaaS could be an efficient process, easily accessible to non-DR experts. Learn about monitoring, testing, executing failovers and failbacks to ensure a "healthy" DR environment.

ONe of my Exchange 2010  Databases -say named  "SAles"  is 160gb and I moved all mailboxes out from "Sales" to Sales2" database and I ran esseutil /d sales.edb  /p on it I thought it this will significantly reduce Database "sales" size however size did n't change much from 160gb down to 145gb???

can ESEUTIL dramatically reduce DB size ?

Hi All,

Attached are two pictures showing the storage quotas that we use in Exchange 2010 so that users get a maximum mailbox size of exactly 2GB and 3GB reported in their Outlook client. Could someone tell me what I need to enter so that the user gets the following:

Issue warning at 3.75gb
prohibit send at 3.9gb
prohibit send / receive at 4.0gb

Also, does anyone know why the "Prohibit send and receive" limit shown in my screenshots aren't exactly 2GB or 3GB yet the Outlook client shows them as Exactly 2GB or 3GB to users? (screenshot attached).

We've tried setting exactly 2GB (2000mb or 2048mb) but this then shows users they have a maximum size of 1.7GB?


Thanks!

Hi Guys,

does anyone have a solution for Campaign monitor to work alongside office 365/exchangeonline

i have found this but it is still in dev: http://www.piesync.com/exchange/campaign-monitor/

is there an alternative or better solution?

the reason we are looking to integrate is so we dont have to manually update the list of email address on campaign monitor, we want this to be automated to some extent.

Thanks,

People,

I've got multiple Exchange Server 2013 running CAS role in my company domain.

AD Sites: Default-First-Site-Name
PRODMBX14.domain.com [MBX & CAS role] --> To be decommissioned, no more mailbox running.
PRODMBX20-VM.domain.com [MBX & CAS role] --> newly built and operational.

AD Sites: Head Office
PRODMBX30-VM.domain.com [MBX role] --> Production.
PRODMBX42-VM.domain.com [MBX & CAS role] --> Production.


But when I browse to the Send Connectors section My domain Internet Email Connector click on Edit then Scoping:

Address Space:
Type SMTP
Domain *
Cost 1

What is source server ? Do I need to add the other CAS server role here to send out email or all Exchange Server in my domain ?
Source Server:
PRODMBX14.domain.com

Get-SendConnector -Identity "My domain Internet Email Connector" | fl

AddressSpaces                : {SMTP:*;1}

Is it really necessary to take all the following steps to put the Exchange 2016 Server into maintenance mode in order to run windows patches and updates. If you were performing an Exchange CU like from CU 4 to CU 5 I could see performing all the steps but just doing windows updates are the following steps needed:

Set the HubTransport component to “Draining”
Suspend-ClusterNode (DAG only)
Disable database copy auto-activation
Set database copy auto-activation policy to "Blocked"
Put server in maintenance mode (Set-ServerComponentState)

This seem to be take alot of time and once you are complete with your maintenance you have to go back an undo all this.

Can't you just move all the active DBs off the servers needing the maintenance and then start your maintenance on those servers.
This is too cumbersome, but if this is necessary I understand but it seems that once all the active DBs are off the servers requiring maintenance, you can state your updates and Exchange will prepare itself to reboot clean.

Exchange 2010 didn't require all this, just move the active DBs and run the StartDagServerMaintenance.ps1 and you were good. I understand that the architecture between 2010 and 2016 are different, so it makes sense on 2016 why you drain the HubTransport component, but is all this truly necessary.

Is my proposal a safe option:

Do this to all the servers requiring maintenance.
Move-ActiveMailboxDatabase -Server <currentserver (this server will require maint.)>…

People,

Further on this question: https://www.experts-exchange.com/questions/29042654/Configuring-Exchange-Server-IP-Less-DAG-with-PowerShell-script.html

Can anyone here please share some best practice and also recommendations or what's the best way of deploying 5x nodes IP-less DAG on Exchange server 2013 Standard Edition ?

Because from what I can see here: http://msexchangeguru.com/2014/03/21/e2013sp1-ip-less-dag/ and most of the blogs, just consist of 2 node DAG with File Share Witness.

Any help and suggestion would be greatly appreciated.

Thanks
