When you send pictures or other files by text from Teams, mobile carriers apply some limits. Keep these in mind so your attachments arrive.

• Size: attachments can be up to 3 MB.
• One at a time: send one attachment per message so you stay under the carrier's size limit.
• File types: the file types that can be delivered are decided by the mobile carriers. Common picture formats are the safest choice.
• File names may change: carriers sometimes rename files in transit, so the recipient may see a string of letters and numbers instead of your file name. The file itself is not affected.
• Links instead of pictures: depending on the carrier, an attachment may arrive as a link inside a text message.
• Storage: attachments are kept for one month. Save anything you need to keep longer.

If a picture message isn't going through, try a smaller file, then contact CallHarbor Support.
