Calendar - Exchange

And it's back for a slightly different element in events, DoNotForwardMeeting:

7/25/17 5:15:46.659 PM CalendarAgent[375]: -[SOAPParser:0x7fb067310860 parser:didStartElement:namespaceURI:qualifiedName:attributes:] Type not found in EWSCalendarItemType for DoNotForwardMeeting (t:DoNotForwardMeeting)

I'm having issues with Calendar saying "There was an error attempting to send your changes to the exchange server"

Using Microsoft Exchange with OS 10.11.6

Also having issues! My mail doesn't get new email and the is constantly saying "Downloading Messages"

Hello,

I can confirm this appears to be an Office 365 issue with Mac OS X 10.11/10.10 and initial work I've done it looks to be an Exchange Mailbox/User issue - it doesn't look like you can fix it from the client side, it has to be done on the Office 365 side. (Possibly they have done some back end changes that have broken compatibility with Mac OS X Calendar).

I did a test by deleting the user and recreating it and importing all their data, this works however it is a tedious process to link everything back in, I have raised it with our local Au providers (Telstra) to get them to investigate and work on it. As a side test I cleared the entire calendar out and put in a single event - this then breaks the Calendar app so it doesn't look to be data/event related either, so appears to be more mailbox/user related.

I don't have much help to offer other than stating that I'm seeing the same issue since March 30 2016. So far MS Office 365 support has not been helpful ("It's only affecting Apple Calendar.app, that's incompatible and we do not support. Call Apple Support.").

There is also a thread over at MS Office 365 community: https://community.office365.com/en-us/f/153/p/437730/1114367

The problem seems to be related to additional elements in Exchange WebServcies.

I updated https://community.office365.com/en-us/f/153/p/437730/1114537#1114537

issue report.

Microsoft has opened a new incident on this topic, EX44658.

Tenant administrators of Office365 can see details here: https://portal.office.com/ServiceStatus/ServiceStatusDetails.aspx?ids=EX44658&ty pe=0&xid=UYUGYxjoxyt94zF515JWpItSzhYu9HvMiBYe0MfeFVo%3d

In case you are not a tenant administrator, here is a summary of the current status as per the Microsoft ticket:

| Current Status: Engineers are reviewing options to deploy the fix

| for the affected users, which is expected to take an extended

| period of time. The functionality will be restored for affected users

| as soon as the fix reaches their environment.

|

| User Impact: Affected users are unable to synchronize Exchange

| Online calendar when connecting via Exchange Web Services (EWS).

| This issue only affects calendar synchronization between Exchange

| Online and the email app on Mac OS X.

| [..]

|

| Preliminary Root Cause: A recent update was deployed that caused a

| configuration issue affecting calendar synchronization via EWS.

(I won't be copying all updates from MS here, this is just a copy&paste to let users who are reaching the thread here via search know that MS is actively working on fixing things.)

I also have this. Calendar was not syncing last night. I removed the account and added it back, and now I have the error symbol against that calendar and lots of the same messages in the log.

Seems maybe some comms problem going to the server as well, the error symbol pops up "Calendar cant refresh events in the calendar".

I have so much trouble with my Calendar under OSX (Yosemite and/or early ElCap), but the apps under iOS just seem to always work. Maybe those teams should share code.

Same Problem

The key error is:

2016-04-05 10:59:32.420 CalendarAgent[12027]: -[SOAPParser:0x7fe9bd99c010 parser:didStartElement:namespaceURI:qualifiedName:attributes:] Type not found in EWSCalendarItemType for IsMeetingPollEvent (t:IsMeetingPollEvent)

And no amount of "clearing caches, removing calendar files, resetting Echange account in system preferences" helps.

What a bummer. I now have to use Outlook mac app to manage my calendar 😟

Dear Jobs, NO!

Don't let any of the OS X Calendar.app coders near the iOS app source code!

I need my iPhone calendar, now that OSX Calendar.app is broken.

I must say that Microsoft is doing a nice job of handling the incident. Update posted yesterday evening for tenant administrators of Offie365:

| Current Status: Engineers have begun to deploy the fix to the affected

| infrastructure. Users will begin to experience service restoration as soon

| as the fix reaches their environment.

|

| User Impact: Affected users are unable to synchronize their Exchange

| Online calendar when connecting via Exchange Web Services (EWS).

| This issue only affects calendar synchronization between Exchange

| Online and the email app on Mac OS X.

|

| Scope of Impact: Your organization is affected by this event. Impact is

| specific to a subset of your users.

| Incident Start Time: Tuesday, March 29, 2016, at 10:47 PM UTC

| Preliminary Root Cause: A recent update was deployed that caused a

| configuration issue affecting calendar synchronization via EWS.

Hi Guys - I'm technical, but no to the level of some of you on this thread so excuse the simplistic question....

Is this a fix that will be deployed to Office 365 by Microsoft that will assist "all" end users in any org? Or is this a fix that will be sent out in the next batch of releases that my company can then choose to apply or hold/wait to install? We're an Office 365 shop and I'm not totally up on where the software actually resides in the new O365 cloud infrastructure.

My hope is that this is something Microsoft will fix and can push without the involvement of my IT department.

Thanks.

Disclaimer: I'm not involved with or speak for Microsoft.

The fix which Microsoft rolls out on Office 365 is done without the support from tenant administrators. That's the whole point of Office 365: you don't need to care about systems administrations tasks (other than configuring your users etc). 🙂

I'm now running OSX10.11.5beta and the problem has resolved. Not sure whether that's the beta or the Microsoft patch mentioned above finding its way to my server.

The problem cleared for me too. I updated to 10.11.5 and reactivated the calendar in internet accounts. I had to shut down Cal and restart it in order to get the calendar to appear but it is not updating.
