SCCM Syncing O365 updates takes a long time

Question

Hello, I was syncing some Office 365 updates in my 2103 SCCM environment. However, the synchronization takes a long time. I started at 18:00 yesterday and it is still synchronizing updates now (it’s 11:30 now). It did have some progress as it has already processed 88% of items (6026 ot of 6771).

One thing I suspected was that we’ve set the supersedence rules to wait 24 months before a surperseded Software update is expired. Is it the reason why it takes so long? Thanks.

Answer 1

24 months? Why would you do that? Also, limit the syncing to relevant products and classifications only.

Answer 2

Hi, @CUCOOPE

After doing some lab tests and reviewing the past ones, here is some information can be used as a reference:

1) When only choosing Office 365 Client in the Product tab, there are 256 items and it only took about 2 minutines to sync.


2) When choosing more pruduces, we had 401 items need to be processed and it took about 3 hours.

Then I compared the two synchronization processes and found that the update will be skipped if it is up to date or was superseded, this action generally takes half a second.

And the updates that need to be synced each will take about 20-30 seconds.

Therefor, if there is no error in the wsyncmgr.log or synchronization continues and completes, it is normal to process 6771 items and take such a long time.

And this also shows that only when there are too many superseded updates, the synchronization time will be greatly affected.
The "months to wait before a superseded software update is expired" means how long that superseded software updates will exit in the console.
It is suggested to view the current wsyncmgr.log, if there are not too many superseded updates, setting this time to 24 months will not affect much.
Or you can adjust the settings if you need.
