Office 365 – Shared Mailboxes Pre-Migration Checks

Posted by on 24 Jan, 2015 in Microsoft, Office 365 | 0 comments

We had a hybrid deployment of Exchange 2010 and office 365. During the testing phase I found that if you have shared mailboxes/calendars that need to be accessed by both on premise exchange users and the users that have been migrated to office 365 then you will need to leave the mailboxes on the on premise server as they can then be accessed by both on premise exchange users and office 365 users (as long as they are on the network where the on premise exchange is located).

The other issue I found was not just migrating shared mailboxes but ANY mailbox to office 365 is that if you have the emails forwarded to another email address the forward is removed so make sure that you make a note of any forwarding on the mailboxes before you start the migration!

Office 365 – Emails sent from iPhone not being received

Posted by on 24 Jan, 2015 in Microsoft, Office 365 | 0 comments

While testing the migration to office 365 I found that once a test mailbox had been migrated and I set up an account on my iPhone 4s (firmware version 7.1) I could not send emails. It worked fine with our on premise Exchange server 2010 account. I was creating and sending the emails and it was no longer in the outbox. The emails were never received and they did not appear in the sent Items. It turned out that there was a bug in the firmware and once I upgraded to version 7.1.2 it worked fine. If you are on version 8 of the firmware it was working fine on version 8.02.

Office 365 – Error When Sending Emails as a Shared Mailbox

Posted by on 24 Jan, 2015 in Microsoft, Office 365 | 0 comments

Setup

  • Hybrid deployment using office 365 and Exchange 2010

 

Issue

After migrating a shared mail box to office 365 from an on premise exchange server I received the following bounce message in outlook when trying to send emails as the shared folder. i.e. send emails as sales@mydomain.com.

 

The following recipient(s) cannot be reached:

     xxxxxxxxx.xxxxxxx@gmail.com on 05/12/2014 15:17

           This message could not be sent. Try sending the message again later, or contact your network administrator. Error is [0x80070005-00000000-00000000].

 

Solution

 

I checked the following to resolve the issue:

  • First of a checked permissions and the users permissions had copied over. They had full access and send as permissions to the shared mailbox.
  • I deleted the cached “from” email address in outlook and the issue was still there
  • I logged into the outlook portal and the email worked fine which made me think the issue was with the outlook profile. I re-created the profile and the issue still remained.
  • I did a little googling and found a couple of possible solutions
  • After setting up a test shared mailbox and migrating that to office 365. It worked fine. After checking the settings on both mailboxes I found the solution for me to be down to the shared mailbox being hidden from the exchange address list. To disable the setting you cannot just tick the box in the office 365 admin portal or in the exchange 2010 hybrid deployment’s office 365 server as you will receive the following error messages:

 

Office 365 admin centre error

The action ‘Set-Mailbox’, ‘HiddenFromAddressListsEnabled’, can’t be performed on the object ‘(Shared Mailbox)’ because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization.

shared_mailbox2

As the changes are synched from AD to disable the setting you need to log into your AD Users and Groups, enable the advanced feature and open up the properties of the shared mailbox. Then select the attribute editor and find the setting:

 

msExchHideFromAddressLists

 

shared_mailbox3

 

Set the value to FALSE and sync the changes up using the DirSync tool. Once complete wait a few minutes then restart outlook (or download the address book changes) and it should work fine.
