HI, I was trying to find the autofill information in an Outlook that is Exchange 365 I figured it would be in suggested contacts, but it isn't.  Can someone guide in finding/exporting/importing this much needed part of Outlook?

Thanks a ton.

trying to make connector in 365 using a powershell script but cannot get it to make the connector use ip address range instead of domain for "how to identify your partner organisation"

there seems to be no documented way of doing it from the syntax of the command "New-InboundConnector" found here

so i am stumped. would love to know how to do it please...


my script is as below currently.

this is what it produces   this is what it does produce (wrong)

Cannot access Exchange 2013 Admin Center. It states  

This organization's certificate has been revoked. Certificate is good until 2020 and the binding is set to that too. Not sure what is next?
Hello, quick question  I just setup a new Exchange 2016 server and i'm getting a lot of 5.3.0 Too many related errors, HARD bounce.
I wonder if this is because the servers do not have a connector between each other.  Do they need one by chance?  Thanks!
I have Exchange 2007 and I'm going to migrate it to Office 365. In the end I want the users in the on premises AD to be the same on the Office 365 so that when I need to create a new user or reset someones password I only need to do it on the on premises AD and have at the same time SSO. There are about 20 users in the exchange server so I want to do it during the weekend in one batch only. What is the better option? Stage or cutover migration? Which is more complex?
Exchange 2007 SP3 RU22 moving to Exchange 2013 (then 2016).  Just about ready to install 2013 and move the mailboxes but need to change it so all clients are using Outlook Anywhere.  Currently have 100 Outlook 2010 clients (Moving to Office 2016 after Exchange 2013 is stable).  Setup Outlook anywhere a while ago and that works but I've only seen it in action on laptops we setup and nothing is done special during each ones setup to make it work.  LOL, I guess I did a good job with that setup...  Too bad I didn't really grasp the full inner workings of it.  My problem now is, how can I switch (and confirm) all my Outlook clients use Outlook Anywhere?  Is that just a DNS adjustment?  Sorry, not an DNS or Exchange expert but have successfully moved from 2003 to 2007 years ago.  Would I just setup the current FQDN of server.domain.local to point to in my DNS?  Or would I change it in Exchange at the receive connectors?  Is there a way to tell which clients are using Outlook anywhere and which aren't?  I have two receive connectors in Exchange 2007 (not sure why I even need both), one named Default of and one named Client of server.domain.local.  When I look at server settings in Outlook on a desktop in the office it's pointing to server.domain.local.  Is there a simple central way to change this without my clients knowing?  If so, they'll most likely just get a certificate warning because of the change? My .com has a valid cert.  Main point is to …
Recently had some email messages that were being sent via Exchange through smtp relay from another system, and the reply address or from was always

During a brief period, instead of, this was replaced with, and then switched back.

Looking at the message headers, I noticed the Return-Path was changed during this period listing

Would there be a valid reason why an admin would change this?

Thanks in advance
After removing our on premise exchange server, we no longer have the ability to edit the "Send on Behalf of" or "Send As" properties of our Active Directory synced distribution lists or mail enabled security groups.
If we create a distribution list, or group in Office 365, we can edit these fields in Office 365.  
Currently, we are looking at deleting our on premise groups/distribution lists, and recreating them in Office 365. (If there is a better way, without using 3rd party tools, please let me know!)

I can use the powershell command "get-adgroup" to find the groups. (I plan on doing distribution lists first, and then mail enabled security groups later, as I have to verify they're not in use for local shares.) and I can use "get-adgroupmember" to find the members of the group.

For ease of creating the new distribution lists in the cloud, it would be nice to have the distribution group name, and email, followed by all members of the group in a file. (Or files.) So that it can be read, while creating the new groups in Office 365.

What is the easiest way to accomplish this?

Thanks for any assistance.
Preparing to upgrade from Exchange 2007 SP3 RU22 sitting on a 2008 Standard server in a 2003 forest/domain functional level.  Used ASDI Edit to locate the schema version and have Forest RangeUpper 14625 and Domain ObjectVersion of 11221, but have Forest ObjectVersion as <not set>.  My understanding is I should be seeing 11222? Should I be concerned?  Can I introduce Exchange 2013 to my domain without finding that number?  I plan on upgrading the domain/forest functional level to 2008 before installing Exchange 2013.  The attached screenshot shows what I see in ASDI Edit.  Am I looking in the wrong place or is something wrong with my setup?View in ASDI Edit

Exchange replication passive service down (accidentaly rebooted active server) how do ,I restart replication from command line
In exchange server I want that if any message arrive with prefix [SPAM] in the subject line; the message must move to spam/junk folder of the respective recipient.

we have been seeing constant increase in OST growth for users.

we are working on get to online mode , but as of now we are trying to get the fast growth of OST to slow down

upon investigating we saw users have lot of shared mailboxes.

while doing research i found this

The users whose .ost files are bloating, do they have shared mailboxes in their outlook?
ANSWER IS yes: if the shared mailboxes are added as "Open these additional mailboxes"  
 If they are added in this manner one may  want to remove the shared mailboxes from there and
 Add them as Email accounts

When we have shared mailboxes opened as additional mailboxes their data is added to the .ost of the user's mailbox. If we add the shared mailboxes as seperate email accounts they will have their own .ost files.  

my question: if we add shared mailbox as additional email accounts, in that situation shared mailbox has seperate .ost file and user mailbox will have seperate .OST file then in both case it adds to same  i.e

shared mail box ost size + 10gb , user mailbox size = 12 gb total 22 gb if we add shared mailbox as additional mailbox still it will be 22 gb

what is the difference

2nd question:

Depending upon the size of respective user’s mailboxes, which is the best option shoudl we go for  rebuilding profile rather than compacting them as it would take hrs.which option works best here to get rid of corrupted fragmented OST file

BTW, users can work while compacting is under way?…
Hi, I would like to search message log in my Exchange 2013, specifically I need to track sender smtp's ip address.

Thank you very much
i have on premise AD and ADFS server.

we have mailboxes in office 365 having E3 licenses.

we dont have any on premise exchange servers.

we had 1 user who went on to soft delete, the user had left sometime back and company decided to hire him back.

generally we have AD policy where after 90 days of user leaving on premise AD account is permanently deleted and user goes into soft delete in office 365.

i saw user isn deleted state in azure AD , so i restored the user, but the user account is in blocked state in office 365

do i need to recreate the account in onpremise AD ?

I'm migrating Exchange 2007 to Office 365 in a very small organization with 20 mailboxs and about 30 users. Besides Exchange Online they'll be using Sharepoint and Skype for business (no migration need for these two). I'm undecided to sync the AD with Office 365 and manage the user creation on premises or use seperate accounts for the domain accounts and for the Office 365 users.

What would you recommend? What are the best practices here?

I've a problem applying a new SHA2 Cert (from 123-Reg) to Exchange 2010

I created the request via the Certificate MMC as a custom request because this SBS 2011 server is SHA1 by default.   Right clicked the Certs and installed both the Intermediate and the actual cert for the host

When I looked in the EMC I didn't have the option to complete the Cert request, so I looked in IIS, the option was there and it completed as expected.

When I opened EMC to assign the Cert to the services SMTP etc, the Certificate page didn't load and generated error object get exchange certificates not found.  upon running Get-ExchangeCertificate from powershell the same error is displayed.

I could assign the new cert to the default web site via ISS, which took care of OWA etc but still not the SMTP services etc

I found that if I remove the new cert from IIS - the EMC worked again and the old certs are shown as normal..

hope that's enough info, any help or ideas would be appreciated?  

Thanks TC
I have a unique issue here and I am no understanding autodiscover and outlookanywhere config enough to get around it.

I have 2 sites with 1 Exchange 2013 box with all roles in each as my production environment. It is fully configured and functioning externally and internally.

My box at the primary site(second site is not internet facing) is sitting on a clustered storage space which is degraded and will not rebuild on the replacement disk, backup attempts crash the cluster disk so day by day data is further compromised by the minute.

My only choice was to attempt to install another box in the primary site and move the mailboxes.

I have deployed a new bow (Exchange 2013 CU21 all roles) and moved my mailbox for testing successfully. Internally everything functions fine for my account, externally autodiscover, owa, outlookanywher do not work.

I dont' seem to be visualizing the proxy functionality correctly or have made changes on the new CAS which is breaking the functionality.

Current config is as such:

= Have changed nothing on the degraded primary site server or the remote sites CAS/Mailbox server
- This may be where I screwed up, but it tested fine internally so I thought the changes had no affect due to the proxying
          - Changed all web services URL's on the new primary site machine to match the degraded machine in preparation for the cutover after the mail box moves were completed.
                    - eg. degraded server autodiscover is …

How do you give a user full mailbox FOLDER access of another user without managing the permissions in Outlook, so via powershell as an admin.


Set-MailboxFolderPermission -Identity William.Tell:\Inbox\SharedFolder -User -AccessRights Owner wont allow the Joe Smith to expand the folder.

I don't want to give Joe Smith any access to view any other content other than whats in that specific folder.

Thanks in advance
There are multiple ways to add an extra mailbox to Outlook. The methods I am aware of are:

1. Auto mapping - Grant full access to a mailbox in Exchange and the mailbox is added automatically in Outlook.
2. Add the mailbox as an extra account in Outlook (options -> info -> add account).
3. Use the "Open additional mailboxes" in the E-mail profile.

I've never found clear explanation when to use a certain method and when not and what are the (dis)advantages of each method. Can somebody point me to a website that explains this or explain this to me?
i have a Exchange 2016 Installation (Hyper-V) I would like to connect from external via Outlook Pop account to get ans send the mails. What do i have to do to make it possible?

I just need update about O365 in hybrid mode with On-Premise Exchange. Two years ago I remember that some permissions like "send as" is not working if the concerning mailboxes are not in same side (one is on premise and other on O365). I heard that this issue has been fixed or improved now. Is that true? Just out of curiosity which Powershell cmd should be run to give "send as"permission?

Have a failing cluster disk with an Exchange 2013 CU16 Std VM on it. Pool will not rebuild on new disk and will only attach if the failing disk is in the array.

Storage was reporting no errors and only found due to failing backups, so backups are not current.

I have decided to install a new Exchange box and attempt to move the mailboxes. Issue is I onlu had access to Exchange 2013 SP1 and CU21 and the failing server is CU16 which is not available.

I do not want to even think about attempt installing CU21 on the failing space. My question is whether it is advisable or is a problem to install CU21 on the new machine and migrate the mailboxes with the version mismatch.

I am stuck, storage will not stay stable for backups, VM moves, or even attempting to copy the vhdx. I know the mailbox moves are high I/O but I don't seem to have a choice to to attempt it.

Will the 16 - 21mismatch be a problem?
