Calendar Invites Time Off with MAPI

Problem reported by Liam Dwyer - 3/9/2021 at 10:21 AM

Resolved

I have discovered an issue with meeting invites (currently it seems to be affecting GotoMeeting invites). This has been noticed in Outlook 2016 and SmarterMail Build 7699 (Jan 29, 2021). Have not update SmarterMail to latest version due to image display issues.

The meeting shows the correct time in Webmail.

The meeting shows the correct time on mobiles using EAS

The meeting shows the correct time in Outlooking using EAS

The meeting time is OFF by one hour later in Outlook using MAPI.

The two tests with Outlook are on the same computer. All timezones on Server, Smartermail, PC and Outlook are set correctly to the same timezone - Eastern Time (US and Canada).

Thanks

Liam

Here is some further troubleshooting. These excerpts are from one of the problematic appointments taken from the calendar .json file on the server.

The first section is from the main portion of the appointment. Times are showing correctly.

{
  "id": 2951213,
  .....
  "dt_start": {
    "dt": "2021-03-11T09:30:00-05:00",
    "tz": "Eastern Standard Time",
    "has_time": true
  },
  "dt_end": {
    "dt": "2021-03-11T11:00:00-05:00",
    "tz": "Eastern Standard Time",
    "has_time": true
  },

This portion is from the "mapi_properties" section of the appointment. Some lines have been removed for display. As you can see, one of the groups of times are off by 1 hour later.

"mapi_properties": {
    ....
    "0x00600040": "2021-03-11T14:30:00",
    "0x00610040": "2021-03-11T16:00:00",
    .....
    "0x92250040": "2021-03-11T14:30:00",
    "0x92240040": "2021-03-11T16:00:00",
    ....
    "0x91340040": "2021-03-11T14:30:00",
    "0x92060003": 90,
    ....
    "0x9310001F": "https://global.gotomeeting.com/join/######";,
    "0x93130040": "2021-03-11T15:30:00",
    "0x93120040": "2021-03-11T17:00:00",
    "0x0E1F000B": false
  }

Looking forward to a response.

Thanks

Liam

Same problem here on Build 7642. I've submitted ticket 048-27DBB1FC-0B08 in hopes of getting advice on which later build is most problem free but corrects this problem so I can update.

I've tried right up to the current release and they all exhibit the same problem.

Just saw this for the first time.

EAS user "A" sent invite from Outlook (EAS) to user "B" on Outlook (MAPI) integration. User B sees the invitation correctly in SM web interface. But in Outlook (MAPI) the time is +1 hour ahead.

This strange bug magically went away on Sunday morning after the clocks changed again for Daylight Savings. Considering this bug only appeared a couple of weeks ago, I am wondering if Smartermail has some internal issue with the proper dates for Daylight Savings. It was behaving as though internally SmarterMail thought the time change was two weeks too early.

Anyway, for now the issue has gone away. I suspect it will be an issue again in the fall :/

This issue is still occurring for us. In US DST started on 14 March, but in our country it only starts on 28th of March. The bug is wreaking havoc here - hopefully it will be fixed before DST actually fixes is (if it does).

In our case we`re seeing times off by 1 or 2 hours. If we knew for sure that at least the bug is always 1h off, then at least we could use the appointments as they are, but we never know if what we see is 1h or 2h off..

Hi all,

This issue was addressed in SmarterMail Build 7751:

Fixed: Adding an appointment via webmail is off by an hour in Outlook (MAPI).

Please let us know if the problem persists post-upgrade!
