Using Microsoft Azure-Exchange on-line, users are able to book an already booked time slot.

Example:  John has placed a series on the Excellence board room to have training in the room for one month continuously.  However, Karen was able to book the room when he already had it booked.

How can we disable the ability to double book? Thanks

Dear Experts, I have a synchronisation problem between our "one and only" DC (WS 2016 Std.) and also "one and only" Exchange 2016. We are opening and editing contacts in AD but they are not automatically synchronized with our exchange. Both are new installation and maybe I've made something wrong or didn't understand the way they are communicating. Please be indulgent, I'm not the best SYS Admin ;-)

Have a great stressfree day and thank you for reading my problem

Best Regards Olivier

Hi experts,
We are in the process of moving user mailboxes from on-prem to Exchange Online, are the mailbox rules (client and server side) moved over automatically?

Thanks all
This is SBS2011 which has Exchange 2010 running on the same server.
I would like to let my associate be the Exchange Admin to fully manage Exchange 2010 on his own PC without working on SBS2011.
Is this possible?
I think the challenges are
1. How can I assign him Exchange Admin privilege? He should not be assigned domain admin.
2. What software should I install on his PC?
3. Anything else?
Please help

I had this question after viewing can I disable Delivery Status Notification for delayed messages and/or undelivery messages?.

Does anybody have any experience with Dells Archive Manager?  

Currently we are migrating our client from Exchange 2003 to O365.   Alot of their historical data (Email's) are sitting on their old 2003 server running Dells Archive Manager.  Recently they had an issue where their email was being stripped of attachments and missing attachments.   We resolved this by running a few SQL commands to remove stripping and we made the attempt to re-hydrate their email.   Apparently it semi worked.   The catch was the attachments re-hydrated within Archive Manager, it did not fully move the regenerated emails with attachments to their physical exchange box.  

What I would like is to get Archive Manager totally out of the picture and move everything from within AM's storage and migrate it over to O365.    Is this even possible to do?  Right now they can access any attachments in their email pending the servers up and AM is up and running.   I was told there was a way to point Archive Manager to O365 but my boss wants it out of the picture.   Can someone advise on how to fully migrate this?
I work for a school and it's important that all correspondence to parents about their child is also copied to a central mailbox that stores information about students organised into student subfolders.

Teachers often forget to CC this mailbox so I wrote a Mail flow rule that automatically copies the email to StudentInfo if the recipient is one of 1600 email addresses. Unfortunately the rule couldn't be created as it contained 75000 characters and the maximum number of characters allowed is 8192.

I could split the rule into 10 smaller rules A-C D-F etc but then I thought is this the most efficient way to achieve this?

Can anyone suggest a better/simpler way of achieving this? Otherwise I'll just get on with creating the ten or so mail flow rules. Thanks in advance.
Is there a fast way to see who/what changes were made in our Exchange 2016 environment...instead of waiting 24 hrs for the Admin Audit log to arrive via email?
Hi expert,

I try to open automatic replies via owa, however it is showing not available, but previously it is working.

Please help thanks!

In preparation for our Office 365 move, I am upgrading our Exchange 2010 to SP3 and then installing the latest roll up. Currently we are on SP2.

I attempted the install for SP3 and it has come up with an error about it not being able to locate a domain controller which is 2003 or later during the readiness check. We recently upgraded our domain controllers to 2019 and demoted the 2008 R2 controllers. We still have one of the 2008 R2 vm's. The domain forest level is 2008 R2. Turns out 2019 isn't compatible with Exchange 2010 as i believe the schema needs to be updated.

Would i be OK joining the 2008 R2 server back to the forest as a controller and then performing the Exchange SP3 upgrade. Then demoting the controller again?


Currently we have two Exchange servers in DAG and two Domain Controllers in one data-center with dedicated Rack.

We would like to completely migrate the Exchange and AD to new data-center. The plan is to deploy/mounted the new rack in old Data-center, to migrate the data from old rack. As, There would not be any site-2-site or VPN link for connectivity between the data-centers.

After the migration the new rack will be moved to new data-center and Exchange will be running from here.

Please suggest an plan to achieve the AD and Exchange Migration and then power-up the servers in new data-center .
Can we still get first-class support from Microsoft if we're more than 4 CU behind the latest? Even if we ignore their suggestion to go to the latest CU?
Hello- I am new to O365 administration. I have been test migrating G-Suite gmail date via IMAP with my O365 staff account and I want to permanently delete my mail box and then create a new mail box to have a 100% clean / new mailbox to perform another email migration test from G-Suite. What is the easier way to do this AND to preserve the O365 account? I have One Drive data I need to keep on this account.

I was looking over this, but I'm concerned it will delete my user account and One Drive data:

Good day,

We are running into some issues when attempting to complete a full VSS backup of one of our Exchange Servers.

The job will complete with warnings, but then we cannot truncate our logs.

Windows 10 Professional 1909
Exchange 2016 CU12

I just installed my new Windows 10 Professional computer this past week and I am trying to install all the applications back.

One application is the Exchange 2016  Management Tools.

When the setup does a system check it found a few items that needed to be completed prior to the install.

I resolved 3 of the 4

The 4th one I thought would be easy it says computer needs to be restarted first.

So I restarted the computer and the check still says it needs to be restarted.

I restarted several times 4 to be exact and still no luck.

I update my computers /servers using WSUS and it shows no pending updates for this computer.

I found a couple of scripts and ran them but no luck they just say TRUE    so I ran it against a few other computers and it shows same results TRUE so not confident that is checking correctly

Any ideas ?
I have Exchange server with 200 emails accounts  if I remove all the emails of 100 emails accounts that can reduce the size of the EDB  database (those 100 emails are not in use but we need them there)
