36	36
37		-The message redelivery overview can be found in the Manage phase of eMagiz. Within Manage you can navigate to Explore -> Redelivery to access the overview. In this overview you can search on the queue name or on the original ID (as can be found in the error message under the header called jms_messageId).
	31	+The message redelivery overview can be found in the Manage phase of eMagiz. Within Manage you can navigate to Error Message -> Message Redelivery to access the overview.
38	38
39		-{{info}}Note that the overview is sorted ascending on date. This means that the oldest message is shown on top and the latest message is shown at the bottom of the list.{{/info}}

41		-[[image:Main.Images.Microlearning.WebHome@intermediate-message-redelivery-redelivery-in-manage-gen3--message-redelivery-overview.png]]
	35	+Once the overview contains messages it will look something as follows. For each message we have a timestamp and two IDs.
42	42
43		-On top of that you have the option to "Retry all", "Delete all" messages or "Refresh" the view. As the naming implies the "Retry all" button will retry all messages that are currently available in the message redelivery functionality. Note that for each message that generates a new error a new entry will be created in the message redelivery functionality. The "Delete all" button removes all messages from the message redelivery functionality. With the "Refresh" button you can refresh the overview to see whether new messages arrived on the queue.

45		-By selecting a specific message your view changes as detail information of your selected message will be shown. In this additional overview you see the message, its headers, some metadata, and various options to execute on message level.
	39	+By selecting a specific message and pressing the Details button eMagiz will search for the accompanying error message from the error message dashboard. If eMagiz can find the accompanying error message eMagiz will show you the error message details.

48	48
49		-After you have selected the specific message you have several additional buttons available. On message level you have the "Retry" and "Delete message" button. They work in a similar fashion as the retry and delete buttons on the overview level only these buttons work **on message level**.
	43	+Note that there is not always an accompanying error message to be found. In those cases eMagiz will show you an empty error messages pop-up.
50	50
51		-By pressing the "Show error message" button you can view the accompanying error message that caused the message to end up in the message redelivery functionality.

	47	+When you want to redeliver a message you simply select the message and press the button Redeliver. In case all errors originate from the same cause and the cause is resolved you could opt for the option "Redeliver All". This will redeliver all messages at once.
54	54
55		-{{warning}}Error messages are only kept for a period of four weeks (when the limit on a hourly basis is not exceeded within this time period). Should eMagiz not be able to retrieve the error message you will be notified on this.{{/warning}}
	49	+[[image:Main.Images.Microlearning.WebHome@intermediate-message-redelivery-redelivery-in-manage--redeliver-options.png]]
56	56
57		-On top of that we have functionality that allows you to save the test message and link it to the correct flow so you can use it as a test message in your flow testing functionality. For this the button "Save as test message" is used. On top of that you can also "Download" your message if there is a need for it.
	51	+Note that when the message could not be redelivered after you press the redeliver button the old message will disappear from the screen and a new message corresponding to the new error will appear again in your list.

61		-Note that there is not always an accompanying error message to be found. In those cases eMagiz will show you an empty error messages pop-up.
	55	+When you determine that it is not relevant anymore to redeliver a certain message you can have the option to remove a message by selecting it and pressing the button "Remove". On top of that you have the option to "Remove All". This will remove all messages at once.
