The mail server is Exchange 2016 on Win 2012R2, AV is Kaspersky.

We tried:
- Disable this email account
- Reinstall app, format all devices of users which installed email
- Create a rule in Transport settings in ECP to block email from this account

BUT we still receive this notification each 15 mins from the Sonicwall. Can you please suggest?
Exchange 2016 CU10 DAG 2 Nodes.

After upgrading to CU10 my exchange servers are having very high memory usage

When I was on CU9 never saw this.

I know exchange use all the memory then releases it but I thing they need to be able to throttle the memory requirements  

Both servers are VM's on VMware ESXI hosts.

Both servers have 32 GB of memory Node1 has 12 CPU's Node 2 has 4 CPU's

What I see is the Microsoft Exchange Diagnostics Service spikes

Microsoft Exchange Store Worker service   is listed many times

Also a service noderunner  

they ae using up most of the memory

Any ideas?  

Thank you,

Have a Exchange 2010 DAG environment with Office 365 Hybird Setup.

We also have a new single exchange 2016 box all setup and ready.

All mailboxes have been moved to office 365, system mailboxes moved to the new 2016 box.

Everything is all working, we want to start retiring the old exchange 2010 environment.

Has anyone done this?

User have full access on shared mailbox. now when sending emails through that shared mail box, sent emails are shown under their personal mailbox sent folder and not under shared mailbox sent folder. I have tried below fix but this keeps the mails in outbox instead, however receiver receives the email.

On the Edit menu, point to New, and then click DWORD Value.
Type DelegateSentItemsStyle, and then press Enter.
Right-click DelegateSentItemsStyle, and then click Modify.
In the Value data box, type 1, and then click OK.
Exit Registry Editor.

We have outlook 2013 in environment.

Please advise!
I'm having a weird issue with the Exchange Resource booking Attendant for Equipment mailboxes in Exchange 2010.

When I send the meeting request with the equipment it creates a duplicate entry in the calendar. One of the entry has the person's name who sent the request. The other has the subject of the meeting as the screen shot shows and all information that was supposed to be stripped out. Further the second entry also has things that should of been removed such as Reminders enabled. Allow repeating meetings is disabled. When we cancel the meeting the first entry is removed and the second stays.

So it looks like it's making the correct entry, and also making another entry with all the information it was supposed to strip out. Then we you cancel the meeting it's only removing the correct entry.

Get-CalendarProcessing shows the following for the resource mailbox.

Exchange 2016: Fresh install, but cannot connect to EMS (or to localhost/ecp), cannot uninstall. What can I do?

The organization have a Exchange 2010 installation working fine. We want to upgrade to Exchange 2016, so we installed a new Windows Server 2016 with all updates, and then we installed the Exchange 2016. Everything looked fine, created a new database on D drive. Created a certificate request, but have not implemented the new certificate yet. All users are still on the old 2010 server. At the same time there was a couple of new 2016 Active Directory server installed without any problems, and the old AD servers that they will replace are still running AD.

We have restarted the new Exchange 2016 server a couple of times, without any changes. When we start EMS we get this error message:

VERBOSE: Connecting to SRF-EX02.srfosl.local.

Setup Office 365 tenant. Got AD Sync working. Setup myemaildomain.co.uk.

Email in and out works.

Have used ADSIEdit to add proxyaddresses. Set my PRIMARY in capitals and this is reflected in the O365 user properties.

However, everytime we send an email.. it is xxx@xxx.onmicrosoft.com

I cannot seem to change it as it is reflected as xxx@myemaildomain.co.uk is the primary reply email address. And of course I can only amend local domain as this is an AD Connect setup.

scenario. Username AA, BB, CC. Domain @sausages.co,uk

UPN AA@sausages.onmicrosoft.com
I want AANAME@sausages.co.uk to be my reply.

No matter what I do, I get aa@sausages.onmicrosoft.com Even tried adding new UPN suffixes in Domains and Trusts.

Can you please advise?

Many thanks in advance

We have Exchange 2013 in place, i recently had to upgrade the servers to Cu20.  Since doing so we are no longer receiving an email notification when mail databases fail over from one server to the other.  We used to receive notifications for this, regardless of if the failover was automatic due to issue or if we did it manual (i.e. to perform maintenance).  I see a lot of references to powershell script "collectovermetrics.ps1" being able to report on this but i am not clear on how this is triggered.  
As I've recently taken over exchange administration, any help in getting the notifications going again would be appreciated.
I am trying to add an exchange profile to Microsoft Office 2016 (windows 10). It picks up the email address, however, when it is authenticating it asks for the credentials, but does not accept them and pops straight back up.

So far i have tried; both repairs for office, autodiscover reg keys, checking autodiscover on dns host, Adding a Disable WAM keys, uninstalling office, removing from domain, windows updates.

I have managed to add the profile to Windows 10 Mail and it works.
Why exchange server 2016 goes down too often

We are migrating from Exchange to O365, we are also using ADFS 3.0.

I have been asked to prevent Outlook 2010 and 2016 clients from accessing mail when off the corporate network. Users must be able to still access their email externally via Office.com and via Active Sync for BB.

I'm not sure where to start and have to produce a matrix of what is achievable without Conditional Access as we do not have licenses.

One of our customers is having an issue with Threat Management Gateway 2010, realise this is now out of support and appears completely forgotten by MS

I have yet to find out build version, whether service pack 1 or 2 is installed

In the Web Proxy (Reverse) logs

Getting 12202 Forefront TMG denied the specified URL

Gives source and destination address

Theres an issue with Exchange EWS clients connecting from MAC Air

Looks to be a request which mentions the autodiscover.xml of client

Any good background on this and best way to troubleshoot appreciated
On prem AD synced to O365. One user out of hundreds has issue where they can’t access OneDrive nor Skype. Gets “user not found in directory”. Tried unassigning and re-assigning licenses no luck. O364 support is unresponsive.
User has never got to use OneDrive or DharePoint so not worried about losing data there, but they do have email in Exchange Online.
Should I remove them from an OU being synced with AAd Connect, let it sync removal of the user in cloud, and then add back to OU? I’m guessing that could re-trigger the SharePoint profile creation which appears to have never happened. But will that wipe out, or restore/reconcile their now-previous mailbox?
We host DL’s that contain contacts that are outside our firm. Usually an email would come into that DL, then that DL would resend to all the members including those of that are outside the firm. This would pass SPF or spoofing checks because Exchange 2013 would use a command called resend-from.

Now some of the recipients systems are blocking it due to SPF and spoofing checks. Microsoft said this was because Exchange 2016, which we now have in the environment, no longer uses that resend-from command and there’s no option.
I have to think other firms use DL’s hosting members from outside, and use Exchange 2016 but I have not heard anything.

If you have any ideas on this that would be great.

Hello Experts.

I am office 365 illiterate, and not sure if this can be done.
We have an on-prem, 2010 Exchange server setup in a domain. We use Office 2013 on each user’s PC (not office 365). So everyone uses Outlook 2013 from there PC’s.
Some of our staff users have their Outlook 2013 setup to access from home using Outlook Anywhere (connecting to Exchange server using HTTP). All is good…….

My boss brings in his brand new laptop with “Office 365 Business” on it (says he got a monthly subscription), and want me to hook it up to our exchange server so he can get his email from home….

I’m thinking no problem, I will just setup like with Outlook Anywhere and we will be good!

I have tried using the options for exchange, Outlook…..none let me use the Exchange server  (mail.yourdomaion.com), just get email address, and password, then it tries and tells me wrong username or password.

So here is my question….
Can you connect up Outlook 365 to our Exchange server (like Outlook Anywhere) or is there some special way you have to do it online?

If you can setup like “Outlook Anywhere” How is this process?

Thanks in Advance

Hello everyone,

I am attempting to perform a targeted search in Exchange 2013 CU21 using Search-Mailbox. My goal is to search only the Deleted Items folder in a user's mailbox for all items older than 90 days and delete the items found. I've tried using folderid, in, and foldername in the search query and all failed. Has anyone been successful using Search-Mailbox is such a way?
We're noticing that more and more of our users are having problems with appointments actively syncing between each other when using Outlook. We need a scheduled appointment to show up immediately, so duplicates are not created. We've taken it to disabling Outlook email caching on each computer so they are all actively syncing updates with the server. Since we've started this there hasn't been any issues until now, but now more and more users are starting to complain about things not showing up fast enough or right away.

We need to find a way to solve or implement a change to fix this problem. It’s odd that it is all of a sudden happening to numerous people. Is the only solution really for me to go to all computers and turn off cache mode? Or is there a bigger issue that could solve this?

I have question for exchange  experts  on exchange 2010 SP3  i have user VIP user a and his calendar is open to view for every one.  I have checked the Ca lander----Permission Default is none But still  people can view his calendar. how i can block every one to view his calendar expect permitted people.
Second  how I can audit that User B  when he viewed  VIP user A Ca lander.

any power shell command to achieve this.

please assist as I need to prevent every one to view VIP User  calendar view.

Ive create this exchange 2016 rule but it's not working if we are sending an email only to one person in the group "Support TI"  
If we are sending an email to the group "Support TI" the rule work but that's not what we want

How can i create a rule that check if a user is part of a distribution group without sending an email to the distribution group but to one user IN the distribution group

Thanks for your help
we have a single exchange server with clients running outlook 2016 locally.

everything has been working fine, but now we have one of users who is asked for credentials each time he runs outlook. when we enter the credentials name@domain.local with the correct password, this is not accepted.

if we cancel the windows security window we get the “need password” notice displayed in the bottom right task bar.

mail still seems to flow though??

we can connect using owa using the same credentials.

the option to prompt for credentials is not enabled.

if i try to add another profile the credentials are again refused.

as this does not affect anyone else, i suspect it may not be a server issue, but i am struggling to identify where the problem is.

can anyone help trap this problem?

many thanks
