[ms office - o365] Office 365 ProPlus Client 1910 Update - Internet Bandwidth

[smarties11]

Hi All,

 

I deployed the 1910 update (monthly channel) for Office365 ProPlus client on Thursday morning, through SCCM.

 

We've noticed that since then, our Internet connection has become increasingly slower. I've looked at the bandwidth utilisation using PRTG, and we're at 95mb+ pretty much solidly since the update was approved. I've looked at our SmoothWall and am seeing a lot of hits to officecdn.microsoft.com and officecdn.microsoft.com.edgesuite.net. I'm just working my way through the SmoothWall bandwidth reports to confirm for certain, but I'm 95% sure that this Office update is the cause.

 

Has anyone else seen this?

At least it worked. SCCM seems to be struggling with the 1910 updates this month. It may be bits related.

 

Have you set your deployment to go out to MS if the content isn't avaliable?

Can office updates use the same p2p sharing system WU uses?

Apologies for the delayed reply. We didn't have the deployment set to go out to Microsoft if content isn't available, however this is what was happening. We were seeing the update fail on lots of clients with error 80070057, and those that were succeeding were download from MS instead of SCCM, presumably because for some reason the clients believed the copy on our SCCM server to be bad. We pulled the update and our bandwidth usage returned to normal levels once those clients that had already started updating had completed.

 

There is now some recognition of the issue on MS Support, apparently they have replaced the update now with one that works, but those clients that have already updated 'may not be able to update further'. They are promising further information on this soon.

Thanks @smarties11 I've been chasing this issue for the last week.
