Before I answer your question a few important bits of info. There are many factors that would cause a exchange email account to run slow. The first step you can take to improve outlook performance locally is to take the users with the extremely large mailboxes and disable Cached Exchange Mode from outlook account settings on there PC. OST file can slow ...

Works perfectly. I would recommend this if you're using different URL's so you can keep using them instead of redirecting to one specific URL. We have about 10 different URLs for different companies (mail.company.com, mail.companyb.com, mail.companyc.com, etc.) and this works perfectly to preserve the URL.

When you relearn SpamAssassin that a message should be spam it should flip the message over from ham to spam or spam to ham. The problem is that SpamAssassin learns about the message on your relay host, but when it is forwarded to your Exchange server the headers have changes since an addition Received line was added. You could give it a try by adding the ...

You just have to add a Where-Object (abbreviated to ?) after Get-Message to select the messages you want to remove. Get-ExchangeServer | ` ?{$_.IsHubTransportServer -eq $true} | ` Get-Queue | ` get-message | ` ? {$_.sender -eq 'Vinc@somedomain.uhoh'} | ` Remove-Message -withNDR $false

We ended up contacting a 3rd party to help with our problem as my research was getting nowhere. The technician started off retrying everything that was mentioned in the question, and the comments. Turns out the build information wasn't 100% accurate, as I pulled it from the wrong source. The real build information revealed we were on Rollup 8. The ...

Yes you can have multiple A Records that point to the same Public IP address and internal server. That is quite normal. The way to look at it is: Your exchange server runs both the autodiscover & the mail service so you can indeed have both pointing to the same exchange server.

Technet has all the information you could want: Reference Depending on your preference for a GUI or PowerShell you can follow the instructions to create a new discovery search against a mailbox or against the entire organization. You can put the items on in-place hold if needed. With your search results in hand, you can then export the items to a PST or ...

Our problem was rather specific to our setup. We have more than one Exchange Server running in parallel with a load balancer acting as AP. The LB was malconfigured which caused it to neglect to offer any authentication method bar NTLM and GSSAPI even after successful STARTTLS handshake. In-depth testing via swaks jetmore.org (can highly recommend this ...

The reason for the problem was the "DelayedAck" setting on the Exchange transport. The receiving server on the "other side" of the relay was taking too long to respond (more than 30 secs) and so the connection we were making timed out and SMTP conversation never completed. (se url I added in the question). The Exchange admin turned off DelayedAck on the ...

Okay, so you're saying that your mail exchange server is doing a reverse DNS check and rejecting the email because that fails, right? I recently had a problem where I was sending emails out via PHP and sendmail and the emails were going in the spambox due to reverse DNS failure as well. For me, the solution was setting a SPF (Sender Policy Framework) record ...

Does your organisation operate its own certificate authority for internal servers? Perhaps you need to add the CA certificates for the Exchange server into the certificate trust store for Exim? A lot of products don't report this error very well (I don't know if Exim does or not). Wireshark (capture first on the server with tcpdump -p -s0 -w /tmp/foo.pcap ...

It seems that sometimes your application sends QUIT command before receiving reply for the "the final dot" of the message (250 for OK). It seems that the MTA (MS Exchange) ignores commands received before it sends the reply. Suggested Fixes: 1) Increase timeout for waiting for the reply, do not send QUIT before receiving it (even when PIPELINING extension ...

If you enable Moderation on the DL, users will not be able to click the "+" sign to expand the group. Attempting to do so in Outlook will result in the following message: Of course, this means someone (or a group of people, if desired) will then have to moderate all messages that are sent to that DL. In our case, we wanted moderation anyway, so this ...

You can do this centrally by creating Contacts for the external recipients in AD and then configuring the forwarding to these Contacts on the relevant user objects in AD.

The Set-MailboxAutoReplyConfiguration cmdlet is probably what you're after: Set-MailboxAutoReplyConfiguration -Identity "Mr. Leaver" -AutoReplyState Disabled In an automation scenario, use the -Confirm:$false switch to circumvent manual confirmation

PDFs == virus. I for one wouldn't allow it. docx is a different story because, while there are macros, by default Word (therefore Outlook's editor) doesn't allow them, but then again you may never know. Even when you want to preview an attachment in Outlook you get a warning, because it essentially executes the file, for all intents and purposes.

Are you looking for Exchange server settings, contacts, mail to follow you. Are you are talking about personal dictionary, client side only rules, etc.? Are you using Outlook 2013 with on premise Exchange, Office 365, etc.?

I don't believe you can install the Windows 7/2008 R2 RSAT on 2012, but if you're using an account that has access to an endpoint on a domain controller (or really any other server with the AD management/RSAT installed), and PowerShell remoting is enabled, you could use implicit remoting to pull those cmdlets into your own session: $SessionParameters = @{ ...

You can use a proxy SMTP address if the message is sent to Exchange through SMTP - in that case Exchange will not change the sender address and will let one of the proxy addresses to be used (you still cannot use an arbitrary address of course). Proxy Manager (http://www.dimastr.com/proxyman/) does that - it is implemented as an Outlook addin, so to an end ...

You cannot replicate mailboxes between an on-premise database and Office 365, so even if you had an appropriate load-balancer, you won't have the actual data you want in both places. Professional advice - ensure that you can do the foundational elements of your planned design before investigating the things that depend on those elements. You cannot assume a ...

Starting from the default configuration of MDaemon "POP before SMTP" you will be unable to receive mails from Office 365 disabling Account Verification settings. The best way (more secure) is to add all EOP IPs to the Trusted IPs list on MDaemon and then flag the options to disable account verification for trusted IPs only: EOP IPs are available at ...

I did some research for a similar question on Stack Overflow. It wasn't around the DevicePhoneNumber, but instead EASDeviceIdentifier, which prior to iOS 7 contained device serial. It is up to the implementer of the ActiveSync protocol to decide what information is given to Exchange when a device is enrolled. It seems all the mobile systems are moving ...

In my opinion, GAL sync and Calendar sharing should be accomplished via Exchange federation. I think this best nails down your 2nd question from both the "ease of setup" and "ease of teardown" requirements. I'm afraid I am ill equipped to answer on the SharePoint Online side. SPO-SPO should be doable, but interacting with a on-premise environment and ...

Check your MX records; verify that they point to the public IP that your Exchange servers use to listen on port 25. Verify that you can connect to port 25 from an external IP. If that fails, verify that you can connect to port 25 from an internal IP. Read the logs for your SMTP connector that receives mail from the internet. (If you've not already enabled ...

You might have an outage on your Exchange Web Services (Free/busy, address book) or Public Folders - or possibly even the RPC VirDir. If you're using MAPI, the connection will fail and it will fallback to trying OA (RPC over HTTP) - but if a service is down, that will also fail, but in the meantime, it keeps asking for your creds as it tries to connect. You ...

Powershell. Use Powershell. If you have the data in an external file already, you can put in a CSV, import that, and loop through it line-by-line to update in bulk.
