Mail merge will not initialize my document

Office 2016.

When trying to do a mail merge, when it comes time to select the document to use, if I select "existing document", then navigate to the document location, select the document, a message appears "trying to initialize and verify", then it just spins without ever loading the document.

If I select "new document", a message " trying to initialize MS WORD" appears. Then no further action, until I have to restart OUTLOOK.

I can open WORD separately with no problem.

Although when I try to open my merge document, I see a message for READ ONLY as the document is locked by another user. But there is only me on this computer.

Any solution/reason?

Start the mail merge in Word, not from the data source application.

If you want to send the Newsletters as an attachment to email messages, use the Merge with Attachments facility of my Merge Tools Add-in that is contained in the MERGE TOOLS ADD-IN.zip file that you can download from:

 https://mergetoolsaddin.com/

Extract the files from the archive and read the:

“READ ME – Setting up and using the Merge Tools Add-in.pdf

to see how to install and use the various tools.

Using those tools, it is possible to perform the following types of merge that cannot be done with Mail Merge “out-of-the-box”:

  • Merge to e-mail messages either with or without attachments, with the documents created by the merge being sent as either Word or PDF attachments or as the body of the e-mail message .  The email messages can, if necessary, also be sent to CC and BCC addresses and the subject of the message can include data from a field in the data source.
  • Merge to individual documents in either Word or PDF format with the filenames being supplied by the data in one of the fields in the data source
  • Many to One type merges, which can be used for creating documents such as invoices where there are multiple records in the data source that have common data in one of the fields
  • Merging to a document that will include a chart that is unique to each record in the data source
  • Merging a document with Content Controls
  • Merging a document that contains Legacy FormFields
  • Duplex Merges
  • Merging to a printer that will collate and staple the output created from each record in the data source.

The requirements for using the system are:

  • The mail merge main document must be of the Letters type, though that does not mean that the output cannot be sent as an e-mail message where relevant.
  • For the Many To One, Merge with Attachments and Merge to Individual Docs utilities, the data source may be either a table or query in an Access database, or in the form of an Excel worksheet. For the Chart Merge utility, see the Mail Merging with Charts document that is included in the Merge Tools Add-in Zip file for additional requirements for the data source for use with that utility
  • For a data source in the form of an Excel worksheet, the field names must be in the first row of the worksheet and there must be a field name in all of the cells in that row that are within the range of columns that contain the data.
  • For both types of data source, the field names must contain only alphanumeric characters (No @,#,$,%,&,(,), etc) and the field names must not start with a numeric character (0-9). The number of characters in the field names, including spaces, must not be more than 40.

The MergeTools Add-in will NOT work with the “New Outlook”, which is just a re-badged version of Windows Mail and like its predecessor, it does not support automation and hence will not send the messages created by the MergeTools Add-in.

Be aware, that any messages that you had tried to send with the “New Outlook” will have been placed in the Outbox of the original Outlook and they will be sent as soon as you revert to that version of Outlook.   If you do not want that to happen, you should put Outlook Off-line, or disconnect your computer from the Internet.

    IMO it's not depending on exact version as my colleague faced it 2-3 months before me and there where like 3 updates in mean time.

    Does anyone exactly know since which version the problem started?

    @Gabriel Bratton: Is there any progress about a fix?

    If the issue started recently try reverting to the build that was available before it started. Builds to revert are on Update History, Update history for Microsoft 365 Apps (listed by date) - Office release notes | Microsoft Learn.

    To revert do these steps:

    1. Open a Command Prompt in Administrator context.
    2. Type or paste the two commands into the Command Prompt window and press Enter after each:

    cd %programfiles%\Common Files\Microsoft Shared\ClickToRun

    officec2rclient.exe /update user updatetoversion=16.0.xxxxx.xxxxx

    Hi,

    Yes - RMB -> run as administrator.

    I am using Windows 11 Pro 24H2 26100.2605 and Office 2021 latest build from January 7th 2025.

    What I did before

    1. In programs menu - fix my office installation
    2. Run Outlook in safe mode -> reboot
    3. Run Word in safe mode -> reboot

    Remove all addons from outlook

    (these steps are worth to try however my friend from next desk didn't perform them and "run as administrator" way worked for him also and he was strugling with mail merge for two months)
