20120113 - Planned Network Maintenance: OCS upgrade to Lync Secure IM
Subject: 13 January 2012 Planned Network Maintenance: OCS upgrade to Lync Secure IM
Details:
- Scheduled start date and time: 01/13/2012 01:00 AM CT
- Scheduled end date and time: 01/13/2012 05:00 AM CT
- System(s) Affected: Microsoft Office Communicator (OCS) which is your Instant Messaging Service will be offline for up to two hours during the maintenance window.
- Expected Impact: For up to two hours during the window, you will not be able to send or receive Instant Messages using OCS. During this time we will be upgrading your OCS service to the latest version, Lync Secure IM. All control panels will be automatically updated to reflect the new services and options. Pricing will NOT change as a result of this upgrade.
- Action required: Both the OCS and Communicator client will work before and after the maintenance. Users on different client versions may have difficulty sending files to each other so we recommend updating your entire organization at once. The Lync client will be available for download within your control panel today alongside the OCS client. Users may upgrade to the Lync client before this maintenance but some new features will be inoperable until the maintenance is complete.

We Answer Your Questions: FAQ
Q: What is the maximum e-mail attachment size?
A: The ETRN.com e-mail servers do not limit the size of individual e-mail attachments. The ETRN.com e-mail servers do impose a 400 MB maximum total message size limit. Individual customers can choose a smaller message size limit. We can also customize the handling of "over-sized" e-mails. Please contact us to discuss your specific needs. A couple of important facts:
1. Attachments are typically encoded in what is called Base64[1]. As a result, the actual length of MIME-compliant Base64-encoded binary data is usually about 137% of the original file size.
2. E-mails often contain both plain text and HTML components. This also increases the overall size of the e-mail.
