I’ve read all the current threads and tried all the suggestions to make this work properly and reliably, yet it simply doesn’t.
I’ve been using eM Client a long time, dating back to 7.xxx and currently on 10.3.2412
The Airsync operation with the Outlook.com calendar works sometimes for reasonably decent stints, but those have become less and less lately, and typically fails at the most unfortunate moments.
When it fails it sometimes pops an error stating “em client [AirSync] Synchronizing folder ‘[email protected]/Calendar’ failed due to the following error: Exception of type ‘MailClient.Protocols.Common.HttpResponseException’ was thrown.”
But other times the calendar simply goes blank and/or has some appointments but adds, moves and changes don’t show up on my other devices (meaning it isn’t uploading/syncing new data).
I obviously like eM Client better than anything else, having been such a long time user. But this has become beyond frustrating. The calendar sync function is just too unreliable which makes it completely useless for something as important as a calendar. It has gotten SO BAD that I’ve had to resort to using Outlook again.
Hence my question: Will Outlook.com Calendar Sync ever get fixed?
Try the latest version just released V10.3.2545 which now sends messages again via SMTP instead of AirSync so might also help with your issue with the Calendar AirSync problem.
Interesting Outlook Calendar wasn’t mentioned, only messages and I don’t think Calendar uses SMTP on the MS side. But release notes are typically incomplete and certainly worth a try.
I like to keep eM Client up to date, and it’s funny the update function in my installed version thinks I’m up to date. But I’ll manually download and install this update to give it a try, even though I’m skeptical. I’ll report back once I install it and give it some time to prove itself for awhile under normal use conditions.
When it fails it sometimes pops an error stating “em client [AirSync] Synchronizing folder ‘[email protected]/Calendar’ failed due to the following error: Exception of type ‘MailClient.Protocols.Common.HttpResponseException’ was thrown.”
I personally carn’t replicate that specific (Response Exception was thrown error) with my Outlook.com eg: IMAP account using eM Client on Windows 11 or Mac Sequoia, but I have seen it happen with another user on this forum.
So I can only suggest next, if you still get the same error with the latest V10.3.2545 version try removing and readding your Outlook account via “Menu / Accounts” using the automatic account wizard and if that fixes the problem.
Note: If you do try removing and readding your Outlook account make a manual backup first via “Menu/ Backup” incase you need to restore for any reason. You can see when the backup is complete in Show Operations via clicking the drop-down on the right of Refresh top left.
If removing and readding your Outlook account made no difference, then if you have a current active paid Pro or Personal version, suggest to go to the VIP support page and login and lodge a support ticket to be investigated.
Things seem to have settled down the past 24-36 hours. I will keep monitoring to see how things go over the long term, but I’m somewhat hopeful I can stop using Outlook and go back to eM Client full time again, for now.
There was no change with Outlook.com calendar which is still based on Airsync protocol (there is no other way how to access it). The problem is that Airsync servers are often failing or not responding, but having logs is always helpful for diagnosing the issues.
It sure would be nice if this issue was fixed, or at least remove this function from the eM Client official feature set list since it appears that this will never get fixed.
The details about my specific issue is in my original post as the first message of this thread.
Calendar AirSync has been unreliable for quite awhile. The claim about not being able to fix a Microsoft outage is understandable but is definitely not the issue as Outlook always works, while eM Client works only occasionally, blanking out my calendar more times than not. eM Client is simply not a reliable AirSync client.
Calendar and Contact entries usually don’t sync until one of the brief instances when eM Client AitSync actually does what it’s supposed to do, sync, but it usually doesn’t.
And all my iDevices work flawlessly, and every other email client I’ve tried. eM Client, running on two difference Windows 11 machines, is the only one I have trouble with using the Calendar and Contact sync with Outlook.com
Worse, eM Client clears all the Calendar items before it tries to sync and just spins. So I lose everything between failed syncs. That makes it pretty useless for this purpose.
Below are the most recent errors, but there are a few others that show up if/when I add something to either the Calendar or Contacts with the hope they would sync with my other devices.
[AirSync] Synchronizing folder ‘[email protected]/Calendar’ failed due to the following error: Exception of type ‘MailClient.Protocols.Common.HttpResponseException’ was thrown.
This ongoing problem, syncing calendar and contacts with Outlook.com, is so disappointing.
After using eM Client for so many years, I’m being forced to go back to using Outlook while searching for a working alternative. It pains me to lose eM Client as I’ve enjoying using it but this problem is simply too much to deal with.
First of all, why can’t eM Client get sync working again as it did in the past?
Second, why must eM Client clear the entire calendar before syncing, which it doesn’t reliably do, thereby losing access to everything while it tries (and fails) to sync? At least it doesn’t do this horrible thing with Contacts.
This is so sad for me, but this issue has been going on unaddressed for far too long and has rendered eM Client pretty useless for my purposes at this point.
