We are using Exchange 2007 on our Outlook 2007 uses a .ost file.  Yesterday I seem to have deleted a "Task" from my Outlook. That Task has a ton of important info.  Would that Task be backed up in our Backup on the server that backs up Exchange?  Or, is that Task just gone and not retrievable?

Dear Experts

I am hoping someone can assist me with the following issue. I have SPF and DKIM configured on my domain, which appear to be setup correctly but when I examine the message header of an email I sent I see the following entry "None (protection.outlook.com: za.cfao.com does not designate permitted sender hosts)"

Just to add I am using Exclaimer for signature management.

Please can someone examine the header below and advised if I configured something incorrectly.

I created a E-discovery search and selected ALL mailboxes via EMC. When I run the search it says I have too many mailboxes. i know the default limit is 5000 for on-prem, we only have 1500 mailboxes.

Any ideas?

Exchange 2010 times out (Primary Target IP responded with:"421 4.4.1 Connection timed out.") when sending to military emails. Restarting these directly through the Exchange Admin Console eventually works, but I can't babysit the server.

some stuff:
Send connector address space is just * with cost set to zero so all mail gets the same priority. Have tried creating a custom send connector with same result.
Set inactivity timeout on connector to 15 mins.
Restarted Exchange Transport and other relevant services as expected after any config changes.
nslookup from server resolves DNS (MX records) for recipient(s)
flushed dns
Talked with someone inside a military base. His suggestion was to try and send through OWA. Sent him an email through Outlook/Exchange and another through OWA. Both are sitting in the outgoing queue waiting to try, then timeout again.

These are set to retry every 10 minutes. If left alone, they hang in the queue, send NDRs to my boss and usually fail in 48 hours. Once she gets an NDR, I get a message to do something and restarting (just right-click "Retry") eventually gets them sent though it may take one or ten tries. I welcome another set of eyes. This has been the norm for about 6 weeks and nothing I can think of changed on our end. Thanks! :)

I'm on Office 365 Outlook and my domain hosted by GoDaddy.  Not sure that comes into play though.

I have multiple accounts in my Outlook email client.  All of a sudden out of nowhere about a week ago, when I delete an email in one of the mailboxes, nothing happens.  It just stays there.   If I click out of the mailbox and back into the mailbox it's gone.  It used to just delete right on the spot.

All my other accounts - Comcast, Hotmail etc. are deleting just fine as I click the delete button.  If I use the 'delete' key on keyboard nothing happens as well.

So something happened to this one account and I can't figure out how to fix it.

Any help is much appreciated!!!

We have a single windows 2012 R2 Host server running 2 Hyperv servers. One is our file server / domain controller running AD and DNS, the other is an Exchange server 2016.

We have a single remote worker that requires access to a shared folder on our file server. He is fully remote working from different sites using many different wifi connections.

What is the easiest way to provide access for this remote connection to the required shared folder, baring in mind he does not have a workstation to remote into on the local network.

He does use Outlook 2016 and has full access to all of his emails, so does have a local account in AD.

Any advice very much appreciated.

Many thanks

Hi expert,

I was wondering how to create alias email for exchange 2016 server?

Existing we have alias email support@company.com (an email address that doesn't have mailbox), and it ties to primary mailbox c@company.com.

All email send to this alias email support@company.com will redirect the email to the primary mailbox c@company.com and then duplicate to other user mailbox.

How to do the same in exchange 2016 server?

Is creating mail contact plus adding mail flow rule in EMC is the only way?

Please advise.

Thanks.

I have an Exchange 2016 DAG setup with 2 servers having the "Content index state" failed and suspended.
Actually on server1 it is failed, and on server2 it is suspended.
Using Exchange powershell commands to catalog the DB did not work most likely because no valid index is available.

What should I do to fix this?

We got quite a bit of phishing/spamming lately so my IT support colleague has recommendation below:
for your inputs/views if the recommendation below is good or any other alternative best practices out there:
We don't have Proofpoint or email security gateway.

"Note that we should keep the Exchange Online rule/filter as empty as possible as rules filtering affects performance on the Exchange Online; every rule/filter is processed on every single email individually, delaying email delivery eventually.

Recommendation is to perform the blocking at our Exchange Online first (for faster turnaround) and highlight the phishing/spamming source to our host (ie MS team supporting O365) and allow them to take the appropriate actions at their end as ultimately, the RBL/DNSBL relies on the origin/host backend infrastructure.

After acknowledgement from the origin/host on the actions taken, we then remove the rule/filter from our Exchange Online"

Hi - Spammed user in our system is being trapped frequently. by external email systems flagged as junk
Here is the rub - The user has a display name with a special character umlaut double dot..

https://stackoverflow.com/questions/15121359/are-international-characters-e-g-umlaut-characters-valid-in-the-local-part-of

the display name has this character  in one letter. - Id like to understand where the display name is analyzed by an email system if at all. using what mechanism - her email address does not contain the special character. so her display name is different than her email address - hos does email system work to check this - Is the only option to remove it from her display name - its a o365 exchange online user.

thanks

I'm trying to install a Custom add-in in Outlook 2016.  I've set up the add-in under Office 365 Exchange Admin, no problem there, but I'm not getting the option for Custom Add-ins under Outlook Store, I only get Store Add-ins & Admin-managed Add-ins.  I'm thinking its some kind of permissions issue but that's as far as I get.  Any suggestions?

Server 2016 running Exchange 2016 CU9 currently. CU12 update is scheduled for this week.

We have IBM Maas360 for our mobile device, MDM. To get email notifications to work in a sandboxed email environment with Maas360, you have to run their Cloud Extender software. This software requires access to Exchange Server/Powershell. Of course, to give the service account access to that, I had to add the account to Organization Management group on exchange. It fails to detect the URL https://mail.exchangeserver.com/Powershell, nor can it pull mailboxes.

If I run this to test auth:  $session = New-PSSession -Configuration Microsoft.Exchange -ConnectionUri Https://mail.exchangeserver.com/PowerShell -Credential $UserCredential

New-PSSession : [mail.exchangeserver.com] Connecting to remote server mail.exchangeserver.com failed with the following error

My office has been using Exchange to run our email system but a month ago we switched to our own domain and moved our email system to that domain.

We're using Outlook as a client.

Meanwhile I had not cancelled the Exchange subscription and now we're getting 2 separate and unique sets of emails to the same single email address.

It seems that anyone who replies to the "mail on the old server" will have their messages routed to the "old mail server" inbox. And anyone who replies to the "mail on the new server" will go to the "new mail server" inbox.

1. If I cancel the (old) Exchange subscription, will "all NEW replies to the mail on the old server" be automatically routed to the "new mail server"?

2. What is the most efficient method to combine the two sets of mail? Is there a software or specific way to bring the "original server mail" to combine with the "new server".  I don't want to risk deleting or overwriting a bunch of old mail.

Thanks in advance for any advice!
