The remote computer It is Outlook 2013. The account is a Exchange account. An on premise Exchange Server 2007 at and the certificate for on that Exchange Server is valid. People can hit OWA at that address and the certificate is good.

   But on this copy of Outlook the first thing that pops up is a Security Alert titled saying the site does not match the certificate. Which is correct. The certificate is for and for some reason Outlook is going to

   So how do you get Outlook to quit using and start using so this error goes away?

Exchange - Outlook Autoreply for each incoming message. I read some sites that say use Out Of Office but that would only generate a response to each unique sender once.

Exchange 2013 On Premise
We have a client with an internal Exchange 2010 server, single server in a single domain with about 40 users, fully patched.  Everything appears to be working perfectly fine with the exception of hub transport rules.

We just started implementing these for this client and only have one two rules to test with - which are identical to another working exchange 2010 setup unrelated to this one

It seems that no matter what i put in for a rule, it's completely ignored and not acted on.

for example:
1. When a message is sent, from [chosen an exact user from the list, call it user1], and sent to [entered my own external email address, call it me], redirect the email to [chosen an exact user from the list, call it user2] for moderation"
user1 sends the email to me, and i get it immediately (never goes to user2 for moderation)

2. another test.  when a message is sent, from users inside the organization, to recipients outside of the organization, send it to [user2 internal user] for moderation"
any user sends any email outbound, the external recipient receives it immediately

3. another test.  "when a message is sent, containing [hello] in the subject, redirect it to [user2] for moderation"
user1 (or anyone) sends an email with [hello] in the subject, it goes right away without moderation (brackets not important)

so, what are some things i can look at as to why exchange isn't acting on hub transport rules?
Can someone please show me how to export the data from the PowerShell script below to a file?  I cannot for the life of me get it done.  Only a blank file is produced.

Have also tried the export-csv cmndlet with same results.

The data comes up on the screen just fine.

Running the script on an Exchange 2013 server.



$Mbx = Get-CASMailbox -Filter {HasActiveSyncDevicePartnership -Eq $true -And -not DisplayName -like "CAS_{*"}; $mbx | foreach {$name = $; $device = get-MobileDeviceStatistics -mailbox $_.identity; $device | foreach {write-host $name, $_.devicemodel, $_.devicephonenumber, $_.deviceid, $_.FirstSyncTime, $_.LastSuccessSync} | out-file -filepath C:\Temp\ActiveSyncDeviceInfoTake1.txt -inputobject $Mbx -encoding ASCII -append -width 120 }
we used to be able to delete emails from public folders on exchange 2013.  we can no longer do that.  Recently converted to mapi settings in exchange but cannot definitively say that is when this started.  This is a manual background maintenance task which is performed whenever there is time.  We cannot even delete one email from public folders.  Deleting from mailboxes still works.  Move will put the email in the new folder but not remove it from old folder.  User accounts have owner rights on the folder and are god mode exchange administrators.  Using both outlook 2013 and 2016.  Exchange version is 15.00.1365.001   which should be CU 19 for Exchange 2013.  This is all on premise.  error message runs through list of things like do less than 4000, make sure you have rights ...

Is there a possible way to find the number of users/mailbox using the digital certificate from outlook client for encryption purpose? It is Exchange on-premises solution.
Any thoughts on that information fro server side?

First Sorry for my English i don't practice so ...

I have a problem :

I want to export all the subfolders in the Inbox Folder to a separate pst

I have found a PS command to list the subfolders :

foreach-object { Get-MailboxFolderStatistics -Identity <MailboxID> -FolderScope Inbox | select-object Name }

Open in new window

This works perfect so i thinked that this going to work :

foreach-object {foreach-object { Get-MailboxFolderStatistics -Identity <MailboxID> -FolderScope Inbox | select-object Name } | New-MailboxExportRequest -Mailbox <MailboxID> -IncludeFolders "Inbox/$_" -FilePath \\Mypath\inbox-$_.pst }

But i see that we can't include pipe into pipe ...

That's where i'm stucked !

Can anyone help a PS/Exchange newbie ?
Recently our company deployed iPhone 8plus with company email. Basically, functions of sending and receiving email is working fine. then I found the Draft folder was not sync'd.
So I went into Settings -> Accounts & Passwords -> Fetch New Data. It's confirmed the corporate email was set to "Push" automatically. Then I taped into corp email and did not found Draft folder under "PUSHED MAILBOXES". There are only Inbox, Sent, Trash, Junk...etc.

Below is the version of iOS and activesync:
Device OS: iOS 11.3.1 15E302
ActiveSync version:      14.1

Appreciated if someone could help to advise what I miss or it's by design that Draft is no longer sync'd

My understanding with DMARC is it allows you to configure your DNS to instruct e-mail servers that receive e-mail from senders from YOUR domain/e-mail server on how to handle a failed DKIM or SPF.
However, what if those recipient servers have their own e-mail gateway that is set to "allow" failed DKIM or failed SPF.
Does the DNS rule at your domain win over the recipient's server's inbound rules?

Can Microsoft 365 office 2016 be used to create an Outlook profile on local exchange server (2013)?
Slow Office365 Tenant to Tenant migration.

I want to migrate slowly from O365 Tenant A (Exchange Online) to a separate O365 Tenant B (Exchange Online).

Users at the original tenant use the DNS domain, users at the the second tenant use the DNS domain

Some challenges are:
- I migrate and cutover User1 to Tenant B. Now he is using the domain How the users not migrated will send emails to User1? One idea that I have is to setup the targetaddress field of that mailbox, so it will forward the emails for that account. And in this way the non-migrated users will be able to send emails seamless to the migrated users.

- Now User1 needs to send emails to Non-Migrated users... What would be the idea here? I Can create a temporal contact on Forest B for all the accounts (and delete them gradually when these mailboxes are migrated). Another option in my mind could be to always send emails to the addresses ending with until the migration is completed. But is anyone of these ideas going to break the autocomplete/cached names in Outlook?.

Any others alternative for this?
Exchange 2010 Mobile phone sync issue

"You have 10 phone partnerships out of the maximum allowed 10 partnerships. After you reach the maximum, you can't create additional partnerships until you delete existing ones from your account. To do so, sign in to Outlook Web App, click Options > Phone > Mobile Phones, and delete any unused partnerships."

I have checked this via OWA as advised, and via the Exchange 2010 Management Console, however there are only 3.

How can I fix this (also, I don't have access to my clients phone, so I'm hoping I can fix this server side)
there is a exchange mailbox database DB10 that the mailboxes are evacuated from. to the newly created database.

When a send a meeting request from my calendar on my Mac,  using an Exchange account, the meeting requests are not delivered
We have a geographically diverse environment with three separate organizations operating together under the same umbrella.

Each of the three has their own O365 tenant.

For corporate reasons, we do not want to fully migrate two of the tenants into a third.

What would we like is to have something like a federated address book, so that contacts and resources could be easily shared between all three. We would like these contacts and resources sync'd so that we do not have to rely upon manual creation and duplication within all three enterprises.

Does anyone have any suggestions on how this sharing of contacts and meeting resources can be accomplished with minimal maintenance?

Thanks in advance for any help!
Hello, all.

We have recently migrated to O365 Exchange Online in hybrid mode.

We have two on-prem Exchange servers. One is Exchange 2007, on which is configured SMTP relay. Another is Exchange 2013 which is used for hybrid management of groups and resources.

We would like to decommission the 2007 and retain the 2013 for management.

Can anyone recommend how best to move SMTP relay to the Exchange 2013 server? Of what other considerations should we be aware when consolidating servers in this situation? Thanks in advance for any guidance and tips!
Public Folder Migration from Exchange 2010 to Exchange Online (365)
With 45GB of Public Folders to migrate, how would you split up the Public Folder Mailboxes?

Are smaller mailboxes quicker?
Are too many mailboxes slower?

Is 1.9GB too small?
Is 4GB to large?

Thank you

I have created a DDG in exchange 2016 under the same OU in which all users is placed, & set a rule the for users whose department is IT move under this DDG, but no user is moving into DDG , Please help.
We have a VDI environment with roaming profiles. We have recently migrated to O365.

Can someone recommend best practice for VDI and Outlook Cached Exchange Mode (CEM)? We have some users with mailboxes 30-50GB in size. That size prevents using cached exchange mode because of the non-persistent VDI. Online mode, also, results in slow Outlook performance.

I have read some accounts of using a network share map for .ost for use with VDI profiles. Is this advisable? Does anyone have any experience doing so?

Or what is considered best practice for CEM and VDI?

Thanks in advance!

However, while i am creating a new user its not take default policy automatically, we have to add it manually. Is there any way to apply default policy one new accounts automatically while creating?
