Its amazing how Microsoft has managed to manipulate and mislead both its partners and paying customers. The list of annoyances and limitations are pretty big misses by my measure.
- Unable to preview PDF documents direclty from the library. PDF documents must be downloaded before they can be viewed.
- Limit of 5000 items per library. Exceeding the configured limit results in the ability to control configuration items, like cascading permission changes.
- Explorer view issues, these are many and highly inconvient.
- Drive mappings to libraries do not stay connected even with SSO. You are forced to visit the library from IE before the WebDAV session can be reestablished.
- Bulk data uploads.
- Limited to 100 items using Upload Multiple Documents.
- Upload speed limit of around 300KB/s when using Explorer View or Upload Multiple Documents.
- Inability to assign multiple email aliases from secondary domain suffixes when no on-premise Exchange server is configured and SSO with AD Sync is also enabled. To enable additional aliases from domains other than the primary requires editing your user objects with ADSIEdit….
- You cannot email external users when you have the same domain enabled with NO services associated. Example, domainabc.com is hosting additional mail for a subset of users via third-party POP service. You configure this domain but don’t enable any services. When you email users at the configured domain all mail is returned undeliverable.
Single Sign-On / AD Sync
- Microsoft AD Sync has to be installed on a 32bit server. In most cases you need an additional Windows license so you an install AD Sync on a 2008 32bit server.
- Cannot disable sync once its enabled.
- ADFS Proxy cannot be installed on Windows 2008 w/o Hyper-V. The ADFS 2.0 installer has a very specific OS SKU requirement.
