  • Force Mailbox Migration With Bad Items To Complete (2020)

    It used to be easy to complete an Exchange Server > Exchange Online move request that had bad items, but this has changed recently.

    Teams Calendar Fails To On-Premises Mailbox

    Article Depreciated: Microsoft now auto-hides the Calendar icon in Teams if your on-premises Exchange Server is not reachable via AutoDiscover V2 and at least Exchange Server 2016 CU3 or later. Once you move your mailbox to Exchange Online (or a supported on-premises version), assuming you did not do any of the below, your Calendar icon…

  • Read Only And Document Download Restrictions in SharePoint Online

    Both SharePoint Online (including OneDrive for Business) and Exchange Online allow a read only mode to be implemented based on certain user or device or network conditions. For these settings in Exchange Online see my other post at https://c7solutions.com/2018/12/read-only-and-attachment-download-restrictions-in-exchange-online.

  • Too Many Folders To Successfully Migrate To Exchange Online

    Exchange Online has a limit of 10,000 folders within a mailbox. If you try and migrate a mailbox with more than this number of folders then it will fail – and that would be expected. But what happens if you have a mailbox with less than this number of folders and it still fails for…

  • Exchange Move Requests | Large Items | And Setting TCP KeepAliveTime To A Large Value

    I have seen this situation a number of times. A large mailbox (or mailbox and archive) wont move to the target because the process of checking what the changes are in the mailbox take too long, the network or Exchange Server times out the users move and then reports the mailbox is locked. The fix…

  • CRM Router and Dynamics CRM V9 Online–No Emails Being Processed

    This one is an interesting one – and it was only resolved by a call to Microsoft Support, who do not document that this setting is required. The scenario is that you upgrade your CRM Router to v9 (as this is required before you upgrade Dynamics to V9) and you enable TLS 1.2 on the…

  • Read Only And Attachment Download Restrictions in Exchange Online

    Microsoft have released a tiny update to Exchange Online that has massive implications. I say tiny in that it take like 30 seconds to implement this (ok, may 60 seconds then). When this is enabled, and below I will describe a simple configuration for this, your users when using Outlook Web Access on a computer…

  • Public Folder Migrations and the Changing Cmdlets

    To complete a public folder migration from Exchange 2013/2016 to Exchange Online you need to run Set-OrganizationConfig -PublicFolderMailboxesLockedForNewConnections $true But if you look at lots of the documentation that is out there with their tips and tricks etc. you will see that lots of them say: Set-OrganizationConfig –PublicFoldersLockedForMigration $true So very near – but its…

  • Test Connectivity Website and TLS 1.2

    An excellent resource for Microsoft Exchange Server and Exchange Online administrators and consultants is the Remote Test Connectivity website at http://exrca.com or https://testconnectivity.microsoft.com/. Here I am going to document an error that indicated that the Exchange Server (in this case) was not working, but we could see that the phone was connecting fine to the…

  • Public Folder Sync–Duplicate Name Error

    I came across this error with a client today and did not find it documented anywhere – so here it is! When running the Public Folder sync script Sync-ModernMailPublicFolders.ps1 which is part of the process of preparing your Exchange Online environment for a public folder migration, you see the following error message: UpdateMailEnabledPublicFolder : Active…

  • Azure Information Protection and SSL Inspection

    I came across this issue the other day, so thought I would add it to my blog. We were trying to get Azure Information Protection operating in a client, and all we could see when checking the download of the templates in File > Info inside an Office application was the following: The sequence of…

  • CannotEnterFinalizationTransientException On Exchange Move Request

    Did not find a lot on the internet on this particular error, so I guess it does not happen very often, but in my case it delayed to move of the mailbox in question by a week or so until I could resolve it. When a mailbox is moving to a different Exchange organization (cross-forest…

  • Anonymous Emails Between On-Premises and Exchange Online

    When you set up Exchange Hybrid, it should configure your Exchange organizations (both on-premises and cloud) to support the fact that an email from a person in one of the organizations should appear as internal to a recipient in the other organization. In Outlook that means you will see “Display Name” at the top of…

  • Send-On-Behalf Permissions in Exchange Online

First, Send-On-Behalf is changing so that it is supported across a hybrid Exchange Server to Exchange Online connection. At the time of writing this is…

  • New Underlying Search Functionality in Exchange Online

    Mentioned during Microsoft Ignite 2017, there is a new search functionality in place within Exchange Online. Not all mailboxes are able to make use of the new functionality, such as hit highlighting and search results being shown in-line with the results highlighted in context with the results. The reason that the functionality is not available…

  • 420 4.2.0 RESOLVER.ADR.Ambiguous; ambiguous address

    This error can turn up in Exchange Server when Exchange Server is trying to resolve the object that it should deliver a message to. Exchange queries Active Directory and expect that if the object exists in the directory, that the object exists only once. If the object exists more than once, this is the error…

  • Exchange Online Migration Batches–How Long Do They Exist For

    When you create a migration batch in Exchange Online, the default setting for a migration is to start the batch immediately and complete manually. So how long can you leave this batch before you need to complete it? As you can see from the below screenshot, the migration batch here was created on Feb 19th,…

  • Office 365 Retention Policies and Hybrid Public Folders

    If you create an Office 365 Retention Policy (in the Security and Compliance Center) that applies to all Exchange Online content then you might find that after the retention policy has been deployed (a day or so later usually) that the policy is in error and there is a message at the top of the…
