2048249 - EWS account.: Reply to all button missing in some messages (even when there are more than 1 recipient (to and cc)

Status: RESOLVED FIXED

(MailNews Core :: Networking: Exchange, defect, P1)

Description

[Vasilis Lourdas]

Attachment: Screenshot

Steps to reproduce:

I just upgraded to v.152 today and in a few messages, althrough there are more than 1 recipient (to and cc), the Reply to all button is missing from the action buttons in the upper right corner. The folder is a EWS account.

I will attach a screenshot.

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:152.0) Gecko/20100101 Thunderbird/152.0

Actual results:

No Reply to all button.

Expected results:

The Reply to all bytton should be there, since the message contains many recipients (to or cc).

Confirming the same behavior on windows 11 clients. Again, it's strange that the issue does not appear in all cases.

Comment 2

[Eleanor Dicharry]

Was able to reproduce reliably on my Mac.

Comment 3

[Eleanor Dicharry]

Looks like this is dependent on which version of thunderbird originally downloaded each message, which is why the behavior is not uniform across messages.

It appears that Exchange servers may not return all requested metadata fields
in the SyncFolderItems EWS operation, so despite the performance hit, we must
perform message synchronization in multiple steps.

This was backed out three times?

How is this possible?

Teething problems from moving to git...

It's now backed out. Which was the fix for the bug.

Comment 8

[Francesco]

Well, a change from TB 152 was backed out, so you have a two affected versions now.

Comment 9

[Eleanor Dicharry]

The fix for this is in today's daily.

Vasilis - Manual intervention is required to fix the data in user profiles affected by this bug. Can you open an affected account with today's (2026-06-26) daily and repair any affected folders. After a repair, the reply all button should be back for all multi-recipient messages (as well as the recipients list in the message table view).

(The repair button is in folder properties)

Upon further inspection, I don't think bug 2029133 is related to this one, so I'm removing it from the see also.

It appears that Exchange servers may not return all requested metadata fields
in the SyncFolderItems EWS operation, so despite the performance hit, we must
perform message synchronization in multiple steps.

This is the original change ported for the release branch.
