I'm having the same issue. I've sent support ticket yesterday with this issue with .grp file containing email message to which responding is causing problem you are also facing (with also screen recording showing this behavior in browser). Today I had another call from another client describing the same issue.

Okay, won't open a duplicate ticket for this then. If you could shared the response that would be great.

We have the same issue, I've received several support notifications of the same error in replying to an email thread.  In our case it was replying to an email chain with multiple email addresses.  We are also on version 7503.

7503 Here as well, inconsistent but multiple users getting this message when replying and cannot send.

Yes we are facing same problem

7503 same and server getting out of working if the first message wil be answered. After that, all services smtp, imap, mapi, pop still stop working one after one.

Same issue with Build 7503. This needs a fix ASAP, we've got a lot of annoyed customers. 

Webio were you able to get a resolution to your ticket?

Nope. Not yet.

Hello SmarterUsers,

We had our first complain about this today. We also need a fix ASAP. Other than that what would be the solution, rollback to previous update ?

EDIT: It also prevent to save the reply as a Draft.

EDIT2: The only way to reply to these messages is to completly remove the original message content from the reply.

EDIT3: could this be related to this changelog entry (7503) ?

Fixed: Replying to a message that uses @media or @ms-viewport in background style tags does not populate the editor. (Note this is a workaround until Froala publishes their fix for the issue.)

Kind regards

Same problem here as well (now ongoing for more than a week) - I would say this is a top priority fix and a build should be made available asap, preferably today/tomorrow. It practically breaks the main functionality of sending emails.

Does someone tried to return to previous version? Today I had to restart my system and now I'm getting every few minutes MailService.exe crash. When I disable remote access to protocols and webmail it looks like service is not crashing so IMHO this is related to some one thing which maybe got corrupted somehow but I don't see in logs (maybe I just don't know where to look) anything which could help me.

EDIT: I've tried to find previous build. Are there any links for previous build available on ST page?

For us, we unfortunately can't go back to the previous release because we announced to some customers that the issues they were having with PLAIN auth since a few months were finally fixed (in 7503).

So downgrading could maybe help with this reply issue but will bring back the other problem.. that is really unconvenient.

For the previous builds, log into your account on smartertools website and on the top right menu (after you're logged, there is a legacy builds menu link).

Yes, actually it seems all previous releases, event recents are already considered legacy...

We have sent a few custom Builds out that have a fix for this issue as well as some other tangential issues. We will have a release out this week, but if you want a custom Build prior to the release (which will come Wednesday or Thursday) please message me. I'll start a ticket with you and get you the Build. 

Hello Derek,

We have an open ticket for this and really need a custom build that fixes this particuar issue which is new from latest update. As being said before in this thread, it's the whole purpose of the product that is defect at the moment => our customers = angry :/

Kind regards,

Sébastien

Hi, Sebastien -- I've replied to your ticket and included the Build link. 

I'm having the same issue. I would like the custom Build link as well please.

From what I was able to test, I think I can confirm the custom build (7308) fixed the issue on our side.

Test build seems to have resolved here as well, at least with the emails I personally had trouble with before.

Great to hear, guys. Thanks for posting. 

Thanks! This addressed my issue. In addition to fixing this issue (failing to send from webmail and unable to save to drafts), it also fixed an issue where Outlook 2019 (using MAPI) would no longer update folders. There were no errors, it would say the folder (Inbox, Deleted Items, etc) was up to date, but it was not... and then in my deleted items there seemed to be a lot of Modification Resolution emails with logs that ended with 2 entries: 

18:28:25 HRESULT: 0x80040115

18:28:25 HrConfMsgAutoResolved failure

Please provide custom build to fix the issue 

Thanks

Binesh

Hi!

Still no new build for this issue? I really hope this gets fixed this week, it's a pretty major bug. 

The yesterday version 7516 fix all by us, without disconnecting outlook accounts, only install update, ready

Build 7516 (Jul 30, 2020) seems to work OK and the issue has not reappeared so far.

Is it possible this error is back in ver 7619? One of our members is unable to reply to emails because of the array dimensions error. That's the first complaint I've seen out of 15 email addresses we host. Using Windows shared server on Hostek.com. Smartermail ver. 7619
