Delete all items in SyncIssues/Conflicts folder on ExchangeOnline server

Hi,

We running some problem in our organization, where a user mailbox folder size - SyncIssues/Conflicts - has almost 33 GB, and it's growing slowly! (mailbox size 100GB)
Sure the Outlook app always downloading the full folder, and reaching the 50 GB .ost limit.
Setting up the app to cache mail from 6 month, but i think this just not a permanently solution here.

In Outlook Online headind the Settings/General/Storage, i want to empty the hole folder with the option, but it's clearly doing NOTHING.

Search the solution overall 3 days and won't get any.
I tried to connect the EXO services whit PowerShell (i'm the administrator, and i have rights), i see the folder, but can't clear it. (-DeleteContet)
Also trying the MFCMapi app, (it's really cool app btw) but i needed to realise this clearing the local folders, not the server foldelrs.

Pff....
Have you guys any, any advice here?

Thank you very much,
Martin

Hi,

maybe a bit stupid question at first:

Have you checked what is inside the syncerror/issues folder? What are the messages there telling? Because there must be a reason for this HUGE amount of data inside that folder. So that could be the first thing to check.

Than the -deletecontent command could be a possible way. What command have you tried? and what error returned?

MFCMapi is realy good. For EXO you can also try "EWS EDITOR". It can do nearly the same. But you have to setup EWS impersonification first!

Hi Michael,

Thanks for the respond!
Yes i checked and it's weird, the mails in the folder is similar some mails in the Inbox folder.

Maybe someone made a rule to forward mail to this folder, i will check it...

The EWS Editor maybe the solution here i think, thank you very much for the suggestion.

I get the app, and make a session with my admin acc. to the user mailbox, and seeing the Conflicts folder, but i running some problem again.

When i want to Empty->Hard delete, the folder, after some "loading" time, i get a Timeout message.

Maybe be the problem is that, i want to delete a huge amount of items?
Can i set the delete process number, example 10.000 item or something?

Thanks,
Martin

@Sp3ar

I tried to connect the EXO services whit PowerShell (i'm the administrator, and i have rights), i see the folder, but can't clear it. (-DeleteContet)

Also trying the MFCMapi app, (it's really cool app btw) but i needed to realise this clearing the local folders, not the server foldelrs.

I am puzzled by these above sentences: From the first sentence, I know that you want to delete those emails from Server side, it will also sync to client side. But from the seconded sentence, you said that you need to release the local folder but remain the server folder.

Here are my suggestions to delete emails:

From the client side, since you could use MFCMapi, why not open Outlook and delete emails from mailbox directly? Both of them could delete email from local cache then sync to server side.

From the Exchange online side, Search-Mailbox cannot used to delete email from a specific folder. You need to EWS to delete email from this mailbox, if your want to do that, I will help you add the dev tag on this thread.

If it doesn't work on your mailbox, could you provide more detailed information about it? It will help us to narrow down this issue.

Hi Kyle,

Thanks for the respond!

I want to delete the mails from the server yes, cause the client always download the full ~33 GB folder.

The using behind of MFCMapi is just a trying point, i realise that is just for the loacal files.

What MichaelHahn-1668 above suggested and so as you, the EWS Editor could be a possible way, but when i want to Empty->Hard delete, the folder, after some "loading" time, i get a Timeout message.

That's because of the lot of amount of items?

Thanks!

I tested MFCMapi in my lab, delete action will sync to server side when you open Outlook and sync with Exchange server:

You can open Outlook and OWA at the same time, then use MFCMapi to delete an email from Inbox, you will see this email disappear from Outlook then disappear from OWA.

About the using of "EWS Editor" is related with Exchange development, I will help you add the correct tag on this thread.
