Office 365 is growing rapidly and companies
are moving more of their social and collaboration needs to the cloud. Users are
uploading more documents to SkyDrive Pro, teams are building numerous team
sites to work with internal teams as well as with external customers and partners,
and companies are establishing their corporate intranet sites.
Based on feedback
and reports on how customers use the service, we’ve made the following
improvements to SharePoint Online:
upload experience: increased file upload limit from 250MB to 2 GB and expanded support
for a broader range of file types.
collection and list lookup limits: increased site collection limit from 3,000 to
10,000 and list lookup threshold to 12 lookups.
Improved self-restoration: increasing
recycle bin retention duration and turning versioning on by default for new
SkyDrive Pro libraries.
These updates will
be rolling out live worldwide over the coming weeks without interruption. Let’s
dive into the details.
Improved file upload
file upload limit to 2 GB
the default SkyDrive Pro storage per user, from 7 GB to 25 GB, with the
ability to further increase to 50 GB or 100 GB. To complement this, we’re also
increasing the per file upload limit, from 250 MB to 2 GB. Users will now be
able to upload and share larger files like CAD drawings, video files, larger
project documents and more-both to their personal SkyDrive Pro and to team site
document libraries. And it is possible to upload more than one file at a time
via drag and drop, the standard file upload dialog box or via SkyDrive
Pro Sync for Windows.

and .dll are now acceptable file types
Online now accepts a broader range of file types, specifically .exe and .dll. This
value is already an option for SharePoint on-premises admins who can add or
remove blocked file types from central administration via the Blocked File Types page. For SharePoint
Online, our telemetry shows that customers want to store these files in the
cloud along with their other content. This
change will eliminate a number of sync failures customers have seen due to
unsupported file types.

Online blocked file type list.
Increased site collection and
list lookup limits
site collection limit to 10,000 site collections per tenant
next few weeks we will be increasing the number of site collections (groups of
websites organized into a hierarchy) each customer can create. Office 365 Enterprise
customers* can create up to 10,000 site collections from within their
SharePoint Online Admin center (If they want to create more than one site
collection at a time, they can do so using the SharePoint
Online Management Shell); the previous site collection limit was 3,000/tenant.
This increase will enable greater flexibility for how you govern and allocate
your SharePoint Online investment across your company.

Government) – Office 365 Small Business and Midsize Business remain at a single
site collection and twenty site collections respectively.
lookup threshold increased to 12 relations
SharePoint to create sophisticated business solutions that reflect the people,
processes and products of their business. These solutions often take
dependencies on information stored in disparate sets of data (or lists). The
sets of data are often managed by different people/groups. Thus, when you
combine lists’ information in a smart way, you achieve critical mapping and preserve
the integrity of your data. To improve the usability of list lookups in
SharePoint Online, we’re increasing the relationship threshold of list lookups
from 8 to 12 relations. This means you can now create more relational
dependencies, thus improving the depth and accuracy of your custom solution

Bin has been increased to 90 days
To help customers recover previous versions or deleted
documents, we’re increasing the time a file will remain in all available
recycle bins (at the site and the site collection level, including your
SkyDrive Pro). Previously, the recycle bin was emptied automatically every 30
days. Now customers will have 90 days to recover deleted documents, lists, list
items, sites, or even full site collections.

will enable versioning by default on newly created SkyDrive Pro libraries, with
10 versions being retained. Versioning helps with deletion errors and
overwriting scenarios. It empowers users to self-restore. It also supports
managed work streams of documents, in which you require declaration of minor or
major revisions with the ease of restoring a known previous version. You can
also programmatically version documents as a step in an approval workflow or
when a document is checked in after edits are completed.

Internet Explorer 10 fix for “Open with Explorer
View” on Windows 7
We also want to highlight an
important related fix. Customers who use Internet Explorer 10 on Windows 7 and
have previously run into issues using the “Open with Explorer View” can now download a hotfix
from the Windows team (x86 & x64-based versions). Once the hotfix is in
place, you’ll be able to successfully open a SharePoint Online document library
in Explorer just like any other desktop folder on your Windows device, and then
drag and drop files between your desktop and SharePoint Online.
There’s a lot of growth in the
SharePoint Online stratosphere. We hope you take advantage of your Office in
the cloud-build solutions, upload business files, share and collaborate with
your peers-and discover the power of working better together.

Q. Does this announcement apply to Office
365 dedicated subscribers?
A. No. The Office 365 dedicated plans are not receiving

Q: Doesn’t allowing EXEs and DLLs subject the server to
remote execution attacks?
A: No. SharePoint will not execute any arbitrary EXEs or
DLLs uploaded by a user to a team site or to their SkyDrive Pro.
Q: Doesn’t allowing EXEs and DLLs subject unknowing
users to potentially sync malicious files from a team site to their desktop?
A: There are multiple layers of defense that make such
an attack unlikely and mitigate its effectiveness:
1. SharePoint will
only accept uploads from authenticated users reducing risks that an outside
attacker could post any malicious files.
2. SharePoint has an
antivirus scanning engine built in to detect malicious files.
3. If user’s attempt
to execute a malicious file in their synced folders, Outlook and Windows have
warning pop-up dialogs requesting consent from the user before the malicious
file can execute.
a. Many users also
have antivirus scanning applications on their client computers and therefore
would detect and quarantine any malicious files.
Finally, should admins have cause to worry about these scenarios, they can
enable auditing to any document library to detect which end user initially
uploaded the malicious file.
